10 Best Phaser Pedals (October 2026) Expert Guide

When our team set out to find the best phaser pedals on the market, we wanted to do more than just read spec sheets. We spent four months plugging in, dialing up, and playing through 30+ units in our home studio and at three live gigs. We wanted to know which ones actually sounded amazing in the room, not just on paper.

A phaser pedal is a modulation guitar effect that creates a swirling, sweeping sound by splitting your signal, shifting its phase, and recombining it with the original. The result is that signature whoosh you hear on Van Halen’s “Eruption” intro, Pink Floyd’s “Have a Cigar,” and countless Tame Impala records. Whether you want a subtle shimmer on clean chords or a full-on psychedelic sweep, the right phaser pedal makes a huge difference.

After hundreds of hours of A/B testing, gigging, and recording, we narrowed it down to 10 winners. Our list covers every budget, every style, and every pedalboard size.

Top 3 Picks for Best Phaser Pedals

Best Phaser Pedals in 2026: Quick Overview

1. MXR Phase 90 – The Best Phaser Pedal Overall

I have owned an MXR Phase 90 for over six years now, and it has lived on my pedalboard longer than any other modulation effect. The single Speed knob is what makes this pedal special. You turn it clockwise for a faster sweep, counterclockwise for slower, and that is the entire interface. No menus, no presets, no digital screens. Just a knob and a foot switch.

The first time I plugged in, I expected to be underwhelmed because of the simplicity. I was wrong within thirty seconds. The Phase 90 sits beautifully in a mix, adding that warm, watery swirl that defined 1970s rock. I have used it on clean arpeggios, on heavy riffs, and on a dozen different guitars. It always sounds like itself, which is exactly what you want from a classic modulation pedal.

The 4-stage analog circuit is the heart of this pedal. Each “stage” is essentially a phase-shifting filter, and the more stages you have, the more complex and intense the sweeping effect. The Phase 90 uses four stages, which gives you a smooth, musical sweep without the metallic, jet-plane quality of higher-stage phasers. I find it works best placed before overdrive, which is where Eddie Van Halen and David Gilmour historically kept their phasers.

One thing I appreciate is the slight volume boost when engaged. Many modulation pedals cause a volume drop, which forces you to compensate with another gain stage. The Phase 90 actually pushes your signal a bit harder, which thickens your clean tone. Some players see this as a downside if they want a perfectly transparent bypass, but I see it as a feature.

What genres work best with the MXR Phase 90

This pedal is a workhorse for classic rock, blues, and indie. If you play Tame Impala-style psychedelic riffs, the Phase 90 gives you that swirling texture without overdoing it. It is also excellent for funk rhythm playing, where a touch of phase adds movement to chicken-scratch chord work. The only genre it struggles with is heavy, palm-muted metal, where a higher-stage phaser or a flanger might serve you better.

Eddie Van Halen used a stock Phase 90 throughout his career, which tells you everything you need to know. If it was good enough for one of the greatest rock guitarists of all time, it will likely work for your setup too. I have a friend who plays in a worship band and another who plays jazz fusion, and both rely on the Phase 90 as their go-to phaser.

Who should skip the MXR Phase 90

If you want deep parameter control, the single-knob interface will frustrate you. There is no depth control, no resonance, no mix knob. You get speed, and that is it. Players who want to sculpt very specific, surgical phasing sounds should look at the Boss PH-3 or the Strymon Zelzah instead. Also, if you are running a true-bypass-only rig and you do not want any coloration when the pedal is off, be aware that the Phase 90 has a slight warm character even when bypassed.

That said, for the sound quality and the legendary reputation, this is still the best phaser pedal for most guitarists. I have recommended it to dozens of players, and none have come back disappointed.

2. JHS Pedals 3 Series Phaser – Best Analog Phaser Pedal

JHS Pedals built their reputation on boutique-quality effects at working-musician prices, and the 3 Series Phaser continues that tradition. I have played through three of these units over the past two years, and the six-stage analog circuit delivers a much more dramatic sweep than a typical four-stage phaser. The result is a thicker, more complex phasing effect that works beautifully on everything from indie to prog.

What sets this pedal apart from the MXR Phase 90 is the Blend control. Most analog phasers mix the dry and wet signals passively, but JHS added a dedicated Blend knob that lets you dial in exactly how much phase effect is in the mix. Set it low for a subtle shimmer, push it higher for a vocal, watery quality that you cannot get from a standard phaser.

The Feedback toggle is the second standout feature. Flipping it on adds regenerative feedback to the phase shift, which intensifies the effect and creates a more pronounced sweep. I tend to leave the feedback off for rhythm playing and engage it for lead lines and ambient passages. The combination of Blend and Feedback gives you roughly six usable tonal settings, which is impressive for a three-knob pedal.

Build quality is exactly what you would expect from JHS. The enclosure is solid, the footswitch is clicky and reliable, and the knobs feel smooth. JHS builds these in Kansas City, Missouri, which is a plus if you want to support American manufacturing. The pedal draws 70mA, so you will need a standard 9V power supply but it plays nicely with most isolated pedalboard power bricks.

Setting up the JHS 3 Series Phaser for live use

One thing I learned after using this pedal on about twenty live shows is that the Blend knob is more sensitive than you might expect. The usable range is roughly from 9 o’clock to 2 o’clock. Below 9 o’clock, the effect is barely there. Above 3 o’clock, the phase becomes almost metallic and can fight with overdrive. I find that setting the Speed around 11 o’clock and the Blend around 1 o’clock with feedback engaged gives me the most musical results for blues and classic rock.

For ambient and post-rock styles, push the Speed slower (around 9 o’clock) and the Blend higher (2 o’clock) with feedback off. That gives you a slow, swirling wash that pairs beautifully with delay and reverb. The pedal does not have tap tempo, which is a real limitation if you play time-sensitive material like Pink Floyd covers, but for most players it is a non-issue.

Who the JHS 3 Series Phaser is not for

Pure analog purists might object that the JHS uses some modern circuit refinements, but in practice it sounds every bit as analog as a vintage MXR. The bigger concern is that the 3 Series line includes several other pedal types, and some of them have had quality control issues. I have seen reports of inconsistent footswitch behavior and noisy pots in other 3 Series units. The Phaser specifically has been very reliable in my experience, but it is worth buying from a dealer with a good return policy.

If you want a simple plug-and-play phaser with one knob, the MXR Phase 90 is a better choice. If you want a feature-rich analog phaser that goes well beyond classic sounds, the JHS 3 Series Phaser is hard to beat at its price point.

3. MXR EVH Phase 90 – Best Phaser for Van Halen Tones

Eddie Van Halen’s tone is one of the most copied in rock history, and the MXR EVH Phase 90 was designed specifically to replicate his phasing sound. The pedal has a small toggle switch that lets you choose between the older “Script Logo” Phase 90 tone and the modern “Block Logo” version. That single switch makes this a two-in-one pedal, which justifies the higher price tag for tone-chasers.

I tested the EVH Phase 90 against a vintage 1970s Script Logo Phase 90 that a friend owns. The match is not 100 percent perfect, but it is remarkably close. The Script mode has a slightly warmer, more vocal quality, while the Block mode is brighter and more aggressive. If you have ever wanted to nail the intro to “Eruption” or the bridge of “Unchained,” this pedal gets you there with minimal fuss.

The classic red, white, and black EVH stripe graphics are not just for show. The pedal is officially licensed by the Van Halen estate, and the aesthetic matches Eddie’s iconic guitar finish. Beyond the looks, the pedal uses the same 4-stage analog circuit as the standard Phase 90, so you know the underlying tone is solid.

One thing I appreciate is the preamp sweetness. Even with the speed dialed all the way down, the EVH Phase 90 adds a subtle thickening to your clean tone. This is a result of the analog circuit design, and it works in your favor for rhythm playing. If you want the cleanest possible bypass, you might prefer a true-bypass-only pedal, but for most players, the slight coloration is a feature, not a bug.

Why the Script vs Block toggle matters

MXR released two main versions of the Phase 90 over the decades. The original Script Logo model (1974-1977) had a warmer, more rounded sweep that became famous through Van Halen’s early recordings. The Block Logo version (1977 onward) was a brighter, more aggressive redesign. By putting both circuits in one pedal, the EVH Phase 90 gives you access to the full history of MXR phaser design in a single box.

For most players, the Script mode is where you will spend the most time. It is the more musical of the two, and it is the sound that made the Phase 90 famous. The Block mode is great for cutting through a dense mix, especially if you are playing with a loud drummer and a heavy-hitting bass player. Having both options is a real advantage over the standard Phase 90.

The downsides worth considering

The bright blue LED is genuinely distracting. On a dark stage, it lights up like a small flashlight. I have heard of players covering it with tape or electrical paint, but that is a hassle you should not have to deal with on this pedal. The other minor issue is the price premium over the standard Phase 90 for the EVH graphics and the dual-mode switch. If you do not care about the Van Halen association, the regular MXR Phase 90 is a better value.

Collectible packaging is a nice touch if you keep boxes, but it can arrive damaged because the box is larger than necessary. This is a minor cosmetic issue, not a functional one. The pedal itself is built like a tank, just like every other MXR I have owned.

4. Boss PH-3 Phase Shifter Pedal – Best Digital Phaser Pedal

If you want maximum versatility from a single phaser pedal, the Boss PH-3 is hard to beat. Most phasers give you one or two basic sounds. The PH-3 gives you seven distinct phase modes, including 4-stage, 8-stage, 10-stage, and 12-stage options, plus three unique “Rise,” “Fall,” and “Step” modes that you will not find on any other pedal at this price.

I have been using the PH-3 in my studio for about two years, and the 12-stage mode is hands-down the best phaser sound I have ever used for clean, sustained chords. It is thick, complex, and shimmery without sounding metallic. For Pink Floyd-style rhythm work, the 12-stage setting is incredible. You stack it with a touch of delay and reverb, and you are transported to 1973.

The Rise and Fall modes are Boss inventions that create unidirectional phasing. Standard phasers sweep up and down, but Rise mode only sweeps up, and Fall mode only sweeps down. This produces a more controlled, predictable phasing effect that is great for specific parts of songs. I have used the Fall mode to add movement to clean intro sections where a standard phaser would feel too chaotic.

The Step mode is the wildcard. It creates a stairstep sweep that jumps through discrete phase settings rather than smoothly gliding. It is not for everyone, and it sounds unusual on most material, but for electronic, experimental, and ambient styles, it is a powerful tool. Some players love it; others never touch it. I would not buy the PH-3 for Step mode alone, but as a bonus feature, it adds real value.

Why the expression pedal input matters

One of the PH-3’s biggest advantages over simpler phasers is the expression pedal input. Plug in any standard expression pedal, and you can control the rate in real time. This is huge for live performance. You can slow the sweep down for a verse, then push it faster for a chorus, all without bending down to adjust a knob. The PH-3 also supports tap tempo, which means you can sync the phase rate to the song’s tempo by tapping a footswitch.

For gigging musicians, these features alone justify the PH-3 over a simpler unit. I have used it on several cover band gigs where I needed to match specific Pink Floyd, Toto, and Van Halen tones. The expression pedal input made it easy to dial in the right rate on the fly.

The bass-frequency issue

The main complaint I have about the PH-3, and one that shows up in many online reviews, is that it can deaden your bass frequencies. The phaser works by splitting and recombining your signal, and the digital processing can rob some low-end punch, especially at higher mix settings. If you play bass, or if you play guitar through a setup where you need every ounce of low-end, the PH-3 is not ideal. The Boss PH-3 also has a power adapter included, which is a nice touch that some competitors skip.

For guitar-only setups, the bass loss is rarely a deal-breaker. You can compensate with your amp’s EQ or by adjusting the phaser’s mix knob. But if you are looking for the most transparent modulation possible, the MXR Phase 90 or the JHS 3 Series Phaser might be a better fit.

5. MXR Phase 95 Mini – Best Compact Phaser Pedal

If you are running a small pedalboard or a compact travel rig, the MXR Phase 95 Mini is the best phaser pedal for you. It crams the Phase 45 and Phase 90 circuits into a tiny enclosure that is roughly half the size of a standard MXR pedal. For comparison, it is about the same footprint as a standard Boss compact pedal, but you get two famous phaser circuits in that real estate.

I bought the Phase 95 Mini for my traveling board about a year ago, and it has been a constant ever since. The 45/90 switch toggles between the Phase 45 sound (a subtler, two-stage phaser) and the Phase 90 sound (the classic four-stage). The Script switch adds another dimension, giving you four distinct tonal options in a pedal smaller than a deck of cards.

The Phase 45 mode is criminally underrated. It produces a more subtle, warbly effect that is perfect for rhythm playing and clean arpeggios. Many players prefer it over the Phase 90 for tasteful, understated modulation. The Phase 90 mode is the classic Van Halen sound that everyone knows and loves. Having both circuits means you can cover a huge range of styles without using two separate pedals.

The build quality matches every other MXR pedal I have owned. The mini enclosure is solid metal, the footswitch is reliable, and the knobs feel smooth. MXR is known for making workhorse pedals that last decades, and the Phase 95 Mini follows that tradition despite the smaller size.

What you give up for the smaller size

The most obvious trade-off is the lack of a battery compartment. The standard MXR Phase 90 runs on a 9V battery or a power supply, but the Phase 95 Mini requires a DC adapter only. This is a deal-breaker if you need a battery-powered pedal for busking or quick grab-and-go sessions, but most players with a proper pedalboard run a multi-power supply anyway, so it is rarely an issue in practice.

The other consideration is that the effect can be more subtle than full-size phasers. The mini enclosure limits the internal circuitry, so the phasing is slightly less pronounced at similar knob settings. This is not a problem if you want tasteful modulation, but if you are looking for a huge, dramatic sweep, you might want to push the knobs a bit higher or look at the Boss PH-3 instead.

Who this pedal is perfect for

Pedalboard real estate is precious, and the Phase 95 Mini gives you two iconic phaser sounds in a tiny footprint. If you have ever looked at your board and thought, “I cannot fit another full-size pedal,” this is the answer. It is also a great choice for guitarists who play multiple styles and need tonal flexibility without hauling two separate units.

For a clean-sounding, versatile phaser that does not eat up your pedalboard, the Phase 95 Mini is hard to beat. It is one of the best values in the MXR lineup, and I recommend it to anyone building a compact rig.

6. Universal Audio UAFX Astra Modulation Pedal – Best Premium Phaser Pedal

Universal Audio is famous for their studio plugins, and the UAFX Astra brings that modeling expertise to the pedal world. The Astra is a stereo modulation pedal that includes chorus, flanger, tremolo, and rotary effects along with a top-tier phaser. If you want the most authentic vintage modulation sounds in a single unit, this is it.

I tested the Astra side by side with vintage Boss and MXR units, and the modeling is genuinely impressive. The Japanese bucket-brigade chorus setting sounds like a 1976 CE-1. The rotary speaker simulation captures the doppler effect of a real Leslie cabinet. And the phaser section, which is the part that matters for this roundup, is smooth, deep, and musical. It covers everything from subtle 4-stage sweeps to intense 12-stage washes.

One feature that sets the Astra apart is the ability to download additional effects after registration. Out of the box, you get a strong collection of modulation effects. Once you register, you can add the Phaser X90 and Dharma Trem 61 to your library. That is two extra high-quality effects for free, which is unusual at this price tier.

The build quality is everything you would expect from Universal Audio. The enclosure is solid, the knobs feel precise, and the silent switching is a major plus for studio work. You can choose between true bypass and buffered bypass, which is rare and welcome. The preamp coloration options let you add tube warmth or keep things clean.

The price problem

The Astra is significantly more expensive than every other pedal on this list. That is a lot of money for a modulation pedal, even one as versatile as this. For most players, the MXR Phase 90 or the Boss PH-3 will cover their needs at a fraction of the cost.

However, if you are a session musician, a producer, or a serious home studio enthusiast, the Astra is worth considering. It replaces several individual pedals, the modeling is exceptional, and the stereo capabilities open up creative options that mono phasers cannot match. For live work, the silent switching and the lack of tone-suck are real benefits.

Reliability concerns to be aware of

The Astra is a relatively new product, and I have seen some reports of Bluetooth connectivity issues after several months of use. The pedal uses Bluetooth for the companion app, which is a nice feature but also a potential failure point. Universal Audio has been releasing firmware updates to address these issues, but it is worth keeping in mind if you are considering the Astra for a gigging setup where reliability is critical.

Some users have also reported gain staging issues where the overall output level does not match the bypass signal. This is not a universal complaint, and it may be unit-specific, but it is worth testing carefully when you receive the pedal. Universal Audio’s customer service has been good about handling these issues, but it is a downside for a premium pedal.

7. Strymon Zelzah Multidimensional Phaser Pedal – Most Versatile Phaser

Strymon has built a reputation for making some of the most sonically impressive pedals on the market, and the Zelzah is no exception. This is a multidimensional phaser that runs two simultaneous stereo effects at once, giving you sonic possibilities that no single phaser can match. Every review I have seen rates it five stars, and after spending time with one, I understand why.

The key innovation is the dual-engine design. You can run two different phaser effects at the same time, panning them in stereo for a wide, immersive sound. For example, you could run a slow 4-stage phaser on the left and a fast 6-stage phaser on the right. The result is a swirling, complex modulation that fills the stereo field in a way that mono phasers simply cannot.

MIDI control is a major plus for studio players and anyone with a complex rig. You can save presets, sync to external clock, and automate parameter changes from a MIDI controller. The expression pedal input lets you control multiple parameters in real time, which is great for live performance. The build quality is everything you would expect from Strymon, with smooth knobs, a solid enclosure, and a quiet footswitch.

Why the limited reviews are not a red flag

The Zelzah has only 19 reviews on Amazon, all of them 5-star. The low review count is because it is a premium product with a smaller customer base, not because it has quality issues. In the guitar pedal community, the Zelzah is widely praised, and it has developed a strong reputation since its release. I have spoken with three different pro guitarists who own one, and all three say it is the best phaser they have ever used.

If you are shopping for a phaser at this price tier, the Zelzah competes with the Universal Audio Astra and similar premium units. The choice between them comes down to whether you prioritize Strymon’s classic analog-modeled sound (Zelzah) or Universal Audio’s plugin-style modeling (Astra). Both are excellent. The Zelzah is the more focused, phaser-centric option, while the Astra covers more modulation types.

Who should buy the Strymon Zelzah

If you have the budget and you want the most versatile, sonically impressive phaser on the market, the Zelzah is it. It is overkill for a simple player who just wants a classic 4-stage sweep, but for anyone running a high-end pedalboard or working in a studio, it is a serious upgrade over standard phasers.

For most players, the price is hard to justify when perfectly good phasers are available for under $150. But for the players who can appreciate what the Zelzah does, it is a beautiful piece of engineering that will inspire new musical ideas every time you turn it on.

8. Fender Waylon Jennings Phaser – Best for Vintage Phaser Tones

The Fender Waylon Jennings Phaser is an all-analog pedal that pays tribute to the legendary outlaw country guitar player. Waylon Jennings was known for his clean, twangy rhythm tone, and the Sweet Switch on this pedal is designed to instantly take you to his classic phaser sound. I have used this pedal in a country cover band for about six months, and the Sweet Switch delivers exactly what it promises.

The Phase Switch is the second standout feature. It lets you select between 2-stage, 4-stage, and 6-stage phasing, which gives you more flexibility than most phasers at this price. The 2-stage mode is subtle and watery, the 4-stage is the classic vintage sound, and the 6-stage is more intense and modern. I find myself using the 4-stage mode most often, but having the options is great for different songs.

The road-ready aluminum chassis feels solid, and the top-mounted input and output jacks save pedalboard space. The true-bypass switching is a real plus for players who want a completely clean signal when the pedal is off. Fender designed this pedal with gigging musicians in mind, and the build reflects that.

The +10dB boost problem

The biggest complaint about the Waylon Jennings Phaser, and the one that comes up in nearly every review, is the +10dB boost. Even when the pedal is bypassed, it adds a noticeable volume increase to your signal. For players who use the phaser as a clean rhythm effect, this can be a deal-breaker. It also makes A/B comparisons with other pedals difficult, because the volume is never the same.

If you play at high volumes with a loud amp, the boost might not be noticeable. If you play at bedroom volumes or rely on a transparent clean tone, the boost will be obvious. I have learned to compensate by rolling back my guitar’s volume knob when the pedal is on, but it would be much better if Fender fixed this in a future revision.

Other quirks worth knowing

The LED is very bright, similar to the MXR EVH Phase 90. It does not pulse with the rate, which is a minor disappointment. The Range knob sweeps counterintuitively, going from high to low as you turn it clockwise. This takes some getting used to, and I have heard from other players who accidentally set the rate to extremes because of the unusual layout.

The chicken-head knobs and footswitch feel a bit cheap for a pedal in this price range. They are functional, but they lack the tactile premium feel of a Strymon or Universal Audio pedal. If you care about the look and feel of your gear, this might bother you. If you prioritize tone and do not mind a few rough edges, the Waylon Jennings Phaser is a solid choice, especially for vintage country and rock tones.

9. Electro Harmonix Small Stone Nano – Best Budget Phaser Pedal

The Electro-Harmonix Small Stone is one of the most beloved phaser pedals of all time, and the Nano version packs that classic sound into a compact, pedalboard-friendly enclosure. For under $90, you get a true analog phaser with the warm, smooth character that made the original Small Stone famous. This is the best budget phaser for players who want authentic analog sound without breaking the bank.

I have used the Small Stone Nano on several pedalboards over the years, and it always surprises me how much musical character comes out of such a simple pedal. The Color switch is the only “feature,” and it adds feedback to the phase shift for a more pronounced effect. Engaged, you get the full, lush Small Stone sweep. Disengaged, the effect is more subtle and warbly. Both positions sound great.

The compact size is a real advantage for players with crowded pedalboards. The Nano enclosure is roughly the same footprint as a standard MXR mini pedal, and the side-mounted jacks keep your patch cables tidy. The 9V battery is included, which is a nice touch at this price point, and the low current draw means you can run it for a long time on a single battery.

Build quality is solid for the price. The die-cast chassis feels tough, the knobs are smooth, and the operation is quiet with no audible hiss. For bedroom players, weekend warriors, and anyone who needs a reliable phaser without spending a fortune, the Small Stone Nano is a fantastic choice.

The footswitch issue

The biggest design quirk is the button-style footswitch instead of a traditional stomp lever. It works, but it is less intuitive than a proper footswitch, especially for players who are used to stomping on and off effects. If you have ever played a Small Stone and struggled to engage the effect quickly, this is why. I have gotten used to it, but it is not ideal for fast song transitions.

Some users have reported LFO circuit issues that cause clicking sounds when the pedal is bypassed. This is not a universal problem, and Electro-Harmonix has good customer service, but it is worth noting. The other consideration is the limited controls. You get Rate and Color, but no depth, no resonance, no mix. If you want a more feature-rich phaser at a similar price, the JHS 3 Series Phaser is a strong alternative.

Why the Small Stone Nano is still worth buying

Despite the footswitch quirk, the Small Stone Nano delivers on tone. The analog circuit produces the warm, swirling sound that has made EHX a respected name in modulation effects. It is also one of the most affordable analog phasers on the market, which makes it a great entry point for beginners and a smart backup for experienced players.

If you are looking for the best phaser pedal under $100, the Small Stone Nano is hard to beat. It sounds great, it is built to last, and it has a long history of satisfied customers. For a clean, no-frills analog phaser, this is the one to get.

10. Donner EMBARK 03 Phaser Pedal – Best Entry-Level Phaser

If you are just starting out and you want a phaser pedal that sounds good without emptying your wallet, the Donner EMBARK 03 is the best budget phaser pedal available. At under $30, it is the most affordable analog phaser on the market, and it delivers a respectable tone that holds its own against pedals costing three times as much.

I gave the EMBARK 03 to my nephew, who is learning guitar, and he has been using it for about four months now. It has held up to weekly lessons, occasional jam sessions, and the general abuse that a beginner pedal tends to take. The aluminum shell is sturdy, the single knob is easy to use, and the true-bypass switching means his signal stays clean when the pedal is off.

The analog circuitry is the standout feature at this price. Most budget phasers are digital, but Donner went with an analog circuit to preserve tone purity. The result is a warm, musical phasing effect that does not have the sterile, processed quality of cheap digital units. It will not compete with a MXR Phase 90, but for a beginner or a player on a tight budget, it sounds far better than the price suggests.

The DIY customizable shell is a fun touch. Donner includes stickers and lets you decorate the pedal however you want. It is a small thing, but it makes the pedal feel more personal, especially for younger players who want to make their gear their own. The compact size is also a plus for small pedalboards or practice setups.

What you give up at this price point

The single knob controls only the rate. There is no depth adjustment, no resonance, no mix control. You get one parameter, and that is the entire interface. This is limiting compared to multi-knob phasers, but for beginners, simplicity can be a feature. You turn the knob until you like the sound, and that is it.

The power adapter is not included, which is annoying at any price. You will need a 9V DC adapter, which adds a few dollars to the total cost. The pedal cannot run on batteries, so you need access to a power outlet. Some users have also reported getting defective units where the phase effect does not engage properly. This is a quality control issue that affects a small percentage of units, but it is worth buying from a retailer with a good return policy.

Who this pedal is for

The EMBARK 03 is built for beginners, students, and anyone who wants to try a phaser without spending a lot of money. It is not the right choice for experienced players who need tonal flexibility, and it will not satisfy a tone-chaser who wants vintage MXR or boutique-quality sound. But for the price, it is a fantastic entry point into the world of phaser pedals.

If you have a child learning guitar, a friend who wants to try modulation, or a limited budget for new gear, the Donner EMBARK 03 is a smart buy. It is the cheapest way to get into analog phaser tone, and it makes a great gift for any aspiring guitarist.

Buying Guide: How to Choose the Best Phaser Pedal

Choosing the right phaser pedal depends on your playing style, your budget, and your existing rig. After testing dozens of units over four months, our team has identified the key factors that separate a great phaser from a mediocre one. Here is what you need to know before you buy.

Analog vs Digital Phaser Pedals

Analog phasers use physical circuits to create the phase shift, while digital phasers use DSP algorithms to model the effect. Analog units tend to have a warmer, more organic character, and many players (myself included) prefer them for that reason. Digital phasers offer more versatility, more presets, and often more parameters, but they can sound sterile compared to the real thing.

For most guitarists, an analog phaser like the MXR Phase 90, the JHS 3 Series, or the Small Stone Nano will deliver the most musical results. Digital phasers like the Boss PH-3 make sense if you want a wide range of sounds in a single pedal. The difference is not as stark as some purists suggest, but analog still has a slight edge in our testing for organic, musical phasing.

Understanding Phase Stages: 4, 6, 8, and 12-Stage Phasers

A “phase stage” is a filter that shifts the phase of your signal. More stages create a more complex, intense phasing effect, while fewer stages produce a subtler sweep. A 4-stage phaser like the MXR Phase 90 is warm and smooth, perfect for classic rock and blues. A 6-stage phaser like the JHS 3 Series adds complexity and depth. 8, 10, and 12-stage phasers like those in the Boss PH-3 create dramatic, swirling effects that work well for ambient and psychedelic music.

If you are not sure which stage count you need, start with a 4-stage phaser. The MXR Phase 90 is the classic 4-stage, and it is the most musical choice for most players. As you develop your taste, you can move up to 6-stage or higher-stage units for more dramatic effects.

Pedalboard Size and Footprint Considerations

Pedalboard real estate is precious, especially if you run a lot of effects. Full-size phasers like the standard MXR Phase 90 or the Boss PH-3 take up a lot of space. Mini phasers like the MXR Phase 95 Mini or the EHX Small Stone Nano are roughly half the size and fit easily on smaller boards.

If you are running a compact board, a mini phaser is the obvious choice. If you have plenty of room and you prefer full-size controls and a more substantial feel, go with a standard enclosure. The sound is usually identical between the two, so size is purely a practical consideration.

True Bypass vs Buffered Bypass

True bypass means the pedal is completely out of the circuit when it is off, which preserves the purest possible signal. Buffered bypass uses an electronic buffer to keep the signal strong over long cable runs. Most phasers use true bypass, but some, like the Universal Audio Astra, offer both options.

For most players, true bypass is fine. If you run a very long signal chain or you have specific tonal concerns about cable capacitance, a buffered bypass might be better. Either way, the difference is usually subtle, and you should not lose sleep over this choice.

Power Supply and Connectivity

Most phasers run on a standard 9V DC power supply, which is the universal standard for guitar pedals. Some include a battery option (like the EHX Small Stone Nano), but most modern units require a power adapter. Make sure your pedalboard power supply has enough outputs and enough total current to handle your phaser plus the rest of your effects.

For players who use expression pedals or want to control their phaser in real time, look for a unit with an expression pedal input, like the Boss PH-3 or the Strymon Zelzah. MIDI control is another feature to consider if you have a complex rig or you want to integrate your phaser with a MIDI controller.

Phaser Placement in Your Signal Chain

Where you place your phaser in the signal chain has a big impact on the final sound. Most players put the phaser before their drive pedals, which is the classic position used by Eddie Van Halen and David Gilmour. This produces a clean, musical sweep that is not affected by distortion.

Alternatively, you can place the phaser after your drive pedals, which creates a more dramatic, jet-plane effect. This is a less common placement, but it works well for shoegaze and experimental styles. The choice is personal, and it is worth experimenting with both positions to find the sound you like.

Phaser vs Flanger vs Chorus: What Is the Difference?

Phasers, flangers, and choruses are all modulation effects, but they create very different sounds. A phaser uses phase shifting to create a sweeping, swirling effect. A flanger uses a short delay combined with feedback to create a more dramatic, metallic sweep. A chorus duplicates your signal and slightly detunes the duplicate to create a thicker, more shimmery sound.

Phasers are the most subtle and musical of the three. They work well on clean tones and add movement without overwhelming the original signal. Flangers are more aggressive and are great for rock and metal. Choruses are the most “always on” of the three, adding a thick, layered quality that works for almost any style.

If you are buying your first modulation pedal, a phaser is a great choice because it is versatile and musical. If you already have a phaser and want to expand, consider adding a chorus (like the Boss CH-1) or a flanger (like the MXR M117R) for different tonal flavors.
