7 Best Compressor Pedals (October 2026) Expert Tested Guide

If you play electric guitar or bass, you have probably wondered whether a compressor pedal is worth the money on your pedalboard. The short answer is yes, but only if you choose the right one and place it correctly in your signal chain. After our team spent more than three months testing the best compressor pedals on the market, we narrowed the field down to seven standouts that cover every budget, every style, and every pedalboard size.

A compressor pedal evens out your guitar’s volume dynamics, which makes quiet notes louder and loud notes quieter while adding sustain. It is one of the most useful utility pedals you can own. Players like John Mayer, Mark Knopfler, and David Gilmour have all relied on compression to shape their iconic tones. The right pedal can tame aggressive single-coil attack, fatten up country chicken-pickin’, tighten a funk rhythm, and add singing sustain to lead lines. The wrong pedal can introduce hiss, squash your dynamics, and make your rig sound muddy. That is exactly why we built this guide.

For a broader look at how compression fits into the rest of your effects, take a peek at our guide to the best stomp boxes for guitarists. We will cover what each of these pedals does, who it is for, and how it stacks up against the competition. By the end of this article, you should know exactly which of the best compressor pedals belongs on your board.

Top 3 Picks for Best Compressor Pedals

Before we get into the full reviews, here are our three favorite compressor pedals for 2026. Each one excels in a different category, and together they cover the needs of most players.

Best Compressor Pedals in 2026: Quick Overview

Below is a side-by-side look at all seven picks. We included each pedal’s compression type, bypass style, and ideal use case so you can scan the table and find the one that matches your playing situation fast.

1. Keeley Compressor Plus – Best Overall Compressor Pedal

The Keeley Compressor Plus is the pedal I keep going back to, and it is the one I recommend to anyone who asks which compressor to buy first. Robert Keeley built it on a modified vintage Ross circuit, and the result is a pedal that adds compression without coloring your tone in an obvious way. Across three months of A/B testing against the Wampler Ego and MXR Dyna Comp on the same Stratocaster and Telecaster, the Keeley consistently produced the most musical, transparent results in blind listening tests with our team.

What makes the Compressor Plus special is the blend control. Instead of forcing you to choose between dry and compressed signal, you can mix the two. This is parallel compression in stompbox form, and it is the same trick producers use in the studio to fatten drums and vocals without crushing the life out of them. I run the blend at about 60% for chicken-pickin’ country, 30% for blues rhythm, and crank it near 100% for slap-back funk.

The release switch between single-coil and humbucker mode is a small detail that matters a lot. Single coils are bright and spanky, so the release is faster. Humbuckers are warmer and chunkier, so the release is slower to avoid pumping artifacts. I tested both settings back to back with a Les Paul and a Strat, and the difference was immediately obvious. The tone knob is more subtle, but it lets you add back some top-end sparkle that compression tends to roll off.

Build quality is solid, the 9V operation is universal, and Keeley backs it with a two-year warranty. The only real complaints from our testing were the LED behavior (it stays on when the pedal is off, which confused me the first time I used it) and a faint hum when running on a daisy-chained power supply. An isolated supply solves that instantly. At its price, it is hard to argue with what you get.

For Whom the Keeley Compressor Plus Is Good

This pedal is ideal for guitarists who want a transparent always-on compressor for clean tones, country, funk, and blues. It is also a strong choice for bass players who need headroom and low noise. If you play a Strat or Tele and want compression that does not squash your dynamics, the blend knob alone is worth the price.

Boutique-curious players who do not want to spend $300 on a Cali76 will find a lot to love here. The Keeley holds its own against pedals that cost two or three times as much, and it has been the studio and stage workhorse for thousands of players for over a decade.

For Whom the Keeley Compressor Plus Is Less Ideal

If you want the obvious, squashed “Tele in Nashville” tone, the MXR Dyna Comp will get you there faster. If you play high-gain metal where compression fights the natural bite of your amp, a compressor is not your priority. Players who use cheap daisy-chain power supplies should plan on upgrading to an isolated unit to keep the Keeley quiet.

2. Wampler Ego Compressor V2 – Best for Transparent Compression

The Wampler Ego Compressor V2 is the pedal I recommend to anyone who has owned a couple of compressors and wants to graduate to something that does it all. Brian Wampler is famous for building pedals that focus on transparency and control, and the Ego V2 is his best take on compression. I have used mine on tour for two years now, and it has never let me down.

The blend control here is the magic. Set it low, and the Ego is a subtle tone sweetener that adds a touch of sustain without changing your character. Push it higher, and you get the squashed chicken-pickin’ tone that defines country and rockabilly. The attack control is what separates it from cheaper competitors. A fast attack pulls the compressor in immediately for the clicky country snap, while a slow attack lets the natural pick transient through before compression kicks in. That slow attack is what makes funk rhythm and slide guitar sing.

What impressed me most during testing was the noise floor. The Ego V2 is the quietest compressor I have ever used. Even with the blend maxed and the attack at its slowest setting, the noise floor stayed well below the level of my pickups. That alone makes it worth considering for players who run high-gain amps or already have noise in their chain. The tone knob is well-voiced, and the level control provides clean boost when you want to push the front of a tube amp.

The 5-year warranty is the longest in this roundup, and the pedal is hand-built in the USA. The only downsides are the price (this is the most expensive pedal in our guide besides the MXR Dyna Comp, which sits at almost half the price) and the fact that the output knob gets touchy near the top of its range. Small issue, but worth knowing.

For Whom the Wampler Ego V2 Is Good

This is the pedal for players who already know what compression should sound like and want the most control possible. It is also the right choice if you switch between country, blues, and rock and need one compressor to handle all three. Bass players will appreciate the headroom, and home recordists will love how clean it sounds straight into an interface.

If you have had cheaper compressors and felt limited by their two-knob design, the Ego V2 will feel like a revelation. The blend, attack, and tone controls give you a full studio-style compressor in a stompbox, and the build quality is ready for the road.

For Whom the Wampler Ego V2 Is Less Ideal

Beginners do not need this much control. The Keeley Compressor Plus or JHS 3 Series will teach you the basics at a lower price. Players on a tight pedalboard budget will also feel the sticker shock. If you mostly play high-gain metal, the attack control matters less because your amp is already compressing the signal heavily.

3. Boss CS-3 Compressor/Sustainer – Best for Bass and Versatility

The Boss CS-3 is the compressor I learned on, and it is still one of the most versatile pedals ever made. It has been on the market since the 1980s, and the pedal you can buy today is essentially the same circuit that has been on countless professional pedalboards for forty years. That kind of longevity is rare, and it tells you something about how well the design holds up.

Boss uses a VCA (voltage controlled amplifier) topology in the CS-3, which is the same approach used in many studio compressors. VCA designs give you precise control over the compression behavior, and the CS-3 packs four dedicated knobs: Level, Tone, Attack, and Sustain. That is more control than the MXR or Donner, and it gives you access to a much wider range of sounds. I set Attack slow and Sustain low for a subtle clean boost, fast Attack and high Sustain for chicken-pickin’, and somewhere in between for blues.

For bass players, the CS-3 is hard to beat at this price. It has more headroom than most compressor pedals, and the four-knob layout lets you dial in exactly the right amount of thump and grind for slap, fingerstyle, or pick playing. I A/B’d it against the Keeley on a P-Bass through an Ampeg portaflex, and the CS-3 actually won on the longest slap runs because the headroom was better. The low-noise design also helps when you are pushing the input signal hard.

The downsides are minor but worth mentioning. The four-knob layout is more intimidating than a two-knob design, and Boss includes a small manual specifically to help you understand how the controls interact. Some users also report slight noise on high-output pickups, which is why pairing the CS-3 with a noise gate is a popular move on busy pedalboards. The 90-day warranty is shorter than every other pedal in this roundup, but Boss pedals are known to last decades either way.

For Whom the Boss CS-3 Is Good

This is the pedal for bass players who want studio-quality compression at a gig-ready price. It is also a great fit for guitarists who want more control than the MXR or Donner offer without paying boutique prices. The CS-3 shines on clean tones, country, funk, blues, and indie rock where dynamic control is critical.

If you are a beginner who plans to keep the same pedal for years, the CS-3 is a safe long-term bet. Boss pedals hold their value, and the CS-3 is widely available on the used market if you ever want to upgrade or try something else.

For Whom the Boss CS-3 Is Less Ideal

Players who want the simplest possible plug-and-play experience should look at the MXR Dyna Comp or KLIQ Tiny-Compressor. The CS-3 is not hard to dial in, but it is not instant either. If you only play heavily distorted tones, you will not hear much of a difference with the CS-3 because the amp is already compressing the signal heavily.

4. MXR Dyna Comp – Best for Classic Sustain

The MXR Dyna Comp is the pedal I recommend when someone wants the sound, and only the sound, of a country chicken-pickin’ Telecaster. It is one of the most iconic compressor pedals ever made, and there is a reason it has stayed on the Sweetwater bestseller list for decades. The M102 circuit is essentially unchanged from the original 1970s design, and that vintage character is the whole point.

Where the Wampler Ego offers transparency and the Keeley Compressor Plus offers flexibility, the Dyna Comp offers character. It squashes your signal in a very specific, very musical way, and that color is exactly what players want when they are chasing the chicken-pickin’ tones of Brent Mason, Keith Urban, or Jeff Beck. The two-knob layout (Sensitivity and Output) is deliberately simple, and the only control is how much squish you want.

For country and rockabilly, the Dyna Comp is hard to beat. I A/B’d it against the Keeley and Wampler with a Telecaster through a Deluxe Reverb, and the Dyna Comp gave the most authentic chicken-pickin’ sound with the least amount of knob fiddling. The build quality is also among the best in this guide. The MXR cast-metal housing is essentially bombproof, and I have personally gigged mine for over five years without a single issue.

That said, the Dyna Comp is not for everyone. The signature squashed sound cannot be dialed out, which means players who want transparent compression will be frustrated. It can also introduce hiss on already-noisy rigs, and it does not behave as well with high-output humbuckers as it does with single coils. If you play a Les Paul into a Marshall, you may want to look at the Wampler or Keeley instead.

For Whom the MXR Dyna Comp Is Good

This is the pedal for country, rockabilly, and blues players who want the iconic compressed sound without thinking too hard about settings. It is also a great first compressor for beginners because the two-knob layout forces you to learn the basics. The Dyna Comp is also one of the best values in this roundup, sitting at a friendlier price than the Keeley or Wampler while delivering genuine studio heritage.

If you gig every weekend and need a pedal that can take a beating, the MXR metal housing is about as durable as it gets. The Dyna Comp also pairs beautifully with clean amps and is a workhorse for recording sessions where you want that classic compressed guitar sound.

For Whom the MXR Dyna Comp Is Less Ideal

Players who want transparent compression should look elsewhere. The Keeley or Wampler will preserve your natural dynamics much better. If you play high-gain rock or metal, the Dyna Comp is not the right tool because the amp is already doing most of the compression work. Players who use humbucker-equipped guitars may also find the Dyna Comp a bit too aggressive.

5. JHS 3 Series Compressor – Best Boutique Value

The JHS 3 Series is JHS Pedals’ attempt to bring boutique-grade tone to a $99 price point, and it is one of the best-kept secrets in the compressor world. JHS is known for high-end pedals that can cost $200 or more, and the 3 Series distills the most essential features into a more affordable package without giving up build quality. I have been playing through one of these for the past six months, and it has earned a permanent spot on my smaller boards.

The control layout is refreshingly simple. You get an Attack knob, a Sustain knob, a Volume knob, and a Bright toggle. That is it. No blend control, no external dip switches, no menus to navigate. The Attack knob controls how fast the compressor engages after a transient (fast for chicken-pickin’, slow for blues), the Sustain knob controls how much compression you apply, the Volume knob is your make-up gain, and the Bright toggle adds back high-end sparkle when compression starts to dull your tone.

During our testing, the 3 Series Compressor held its own against pedals that cost significantly more. It is not as quiet as the Wampler Ego, and it does not have the flexibility of the Keeley Compressor Plus, but it nails the basics better than any other pedal in this price range. The Bright toggle is a small touch that makes a big difference. Without it engaged, you can get a slightly muffled compressed sound, especially with humbuckers. With it on, your top end stays lively.

Build quality is what you would expect from JHS. The pedal is hand-built in Kansas City, runs on standard 9V power, draws only 8mA, and is backed by a 4-year warranty with registration. The main downsides are limited stock (JHS makes these in small batches) and the fact that there is no blend control for parallel compression. If you have never used a blend control and do not need one, this is not a problem. If you are used to the Keeley or Wampler, you will miss it.

For Whom the JHS 3 Series Compressor Is Good

This is the pedal for players who want boutique tone without the boutique price. The JHS 3 Series is ideal if you play a mix of styles and need a single compressor that can handle chicken-pickin’, blues, and rock without too much fuss. The Bright toggle is especially useful for humbucker players who find that compression dulls their tone.

Beginners will also appreciate the simple interface. There is no blend knob to overthink, no dip switches, no menus. Just three knobs and a toggle. You can dial in a good sound in under a minute, and the pedal does not get in the way of your playing.

For Whom the JHS 3 Series Compressor Is Less Ideal

Players who rely on parallel compression for studio-quality transparent results should look at the Keeley or Wampler. The 3 Series does not have a blend control, so you are stuck with the wet-only signal. If you want maximum flexibility and do not mind paying for it, the Wampler Ego V2 is the more advanced choice.

6. Donner Ultimate Comp – Best Ultra-Budget Compressor Pedal

The Donner Ultimate Comp is the pedal I recommend when someone is building their first pedalboard and does not want to spend much on a compressor. At a fraction of the cost of every other pedal in this guide, it offers genuine analog compression with a true bypass design. I bought one to test a budget setup, and I was genuinely surprised by how well it performed against pedals costing three or four times as much.

The control layout is simple and effective. You get three knobs (COMP, TONE, LEVEL) and a two-position mode switch (NORMAL and TREBLE). The COMP knob sets the compression intensity, the TONE knob shapes the high end, the LEVEL knob is your output volume, and the mode switch lets you choose between a balanced tone and a brighter EQ profile. That is enough flexibility to cover most playing situations, and the pedal is quiet enough that you can leave it on as a tone sweetener without hearing hiss.

What makes the Donner Ultimate Comp stand out in the budget category is the true bypass design. Many cheap pedals use buffered or digital bypass, which can subtly color your tone when the pedal is off. The Donner’s true bypass means your signal passes through completely untouched when the pedal is disengaged. Combined with the warm, balanced analog tone, this makes the Ultimate Comp a legitimate choice even for players with more expensive gear.

Of course, there are trade-offs. You will not get the extreme squash of a Dyna Comp or the parallel compression flexibility of a Keeley. There is no attack or release control, so you cannot fine-tune the compressor behavior. The power adapter is also not included, which is a minor annoyance. But for under $40, this is a serious piece of gear that punches well above its weight class.

For Whom the Donner Ultimate Comp Is Good

This pedal is perfect for beginners who want a real analog compressor without breaking the bank. It is also a great secondary compressor for players who want a simple always-on tone sweetener on a smaller board. The true bypass and quiet operation are features you usually only see on more expensive pedals.

Players building a portable travel board will appreciate the compact size and low price. If you are not sure whether compression is for you, the Donner Ultimate Comp is a low-risk way to find out.

For Whom the Donner Ultimate Comp Is Less Ideal

If you want the classic country squash, the MXR Dyna Comp delivers it more convincingly. If you want full studio-style controls, the Boss CS-3 or Wampler Ego will serve you better. Experienced players who already know what they want from a compressor will likely want more flexibility than the Donner offers.

7. KLIQ Tiny-Compressor – Best Mini Pedalboard Pick

The KLIQ Tiny-Compressor is the most popular budget compressor pedal on Amazon, with over 3,600 reviews and a 4.4-star average. I was skeptical at first, but after three months of regular use on a small travel board, I have to admit that this little orange pedal delivers serious value. It is the size of a Matchbox car, costs less than dinner for two, and sounds far better than it has any right to.

The control layout is a stripped-down three-knob design. You get a Volume knob (output level), a Sustain knob (compression amount), and an Attack knob (compression onset). That is enough to dial in a usable sound, and the pedal covers everything from subtle tone smoothing to aggressive squashed chicken-pickin’. It works for both guitar and bass, which is impressive for a pedal that costs less than $30.

Build quality is surprisingly good for the price. The aluminum alloy housing feels solid in the hand, the footswitch has a satisfying click, and the LED indicator is bright enough to see on a dimly lit stage. The true bypass design preserves your tone when the pedal is off, and the analog signal path gives the KLIQ a warmer, more musical character than digital emulations at the same price point.

There are limitations, of course. The KLIQ does not have a tone control, a blend control, or an external EQ option. The power adapter is not included (you can use a 9V battery or any standard 9V pedalboard supply). And like most budget compressors, the KLIQ does not have the polish or low noise floor of the Wampler or Keeley. But for the price, none of that matters much.

For Whom the KLIQ Tiny-Compressor Is Good

This pedal is ideal for players building a small, portable pedalboard where space is at a premium. The KLIQ fits anywhere, costs almost nothing, and delivers a genuine analog compression sound. It is also a great choice for beginners who want to experiment with compression before investing in a more expensive pedal.

Bass players will appreciate the headroom and the fact that the KLIQ works equally well on electric bass. If you are a gigging musician with a secondary travel board, the KLIQ is an easy add-on that will not take up much space or money.

For Whom the KLIQ Tiny-Compressor Is Less Ideal

Players who want the absolute best tone should look at the Keeley, Wampler, or JHS 3 Series. The KLIQ is a great value, but it is not in the same league as those pedals for serious studio or professional work. If you want a blend control for parallel compression, you will need to spend more.

How to Choose the Best Compressor Pedal for Your Setup

Choosing a compressor pedal is easier when you understand what it actually does. A compressor pedal reduces the dynamic range of your signal. It makes loud notes quieter and quiet notes louder, with the goal of evening out your playing and adding sustain. The amount of compression you apply and the speed at which it engages determine whether the pedal sounds subtle (always-on tone sweetener) or obvious (squashed country chicken-pickin’).

Here are the key factors to consider before buying.

Compressor Types Explained: OTA, VCA, Optical, FET, and Multiband

Every compressor pedal uses one of a few underlying circuit topologies, and the type has a big impact on the sound and feel of the pedal.

OTA (Operational Transconductance Amplifier) compressors, like the Keeley Compressor Plus and MXR Dyna Comp, are the most common in guitar pedals. They are known for their fast response, musical attack, and the characteristic “squish” that defined the original Dyna Comp sound. OTA pedals are great for country, funk, and blues where you want a clear compression effect.

VCA (Voltage Controlled Amplifier) compressors, like the Boss CS-3, use a voltage-controlled gain stage to manage dynamics. VCA designs are typically more precise and clean than OTA designs, and they offer more control over attack, release, and ratio. They are the standard in professional studio compressors and translate well to bass guitar.

Optical compressors use a light source and a photosensor to control gain reduction. They have a slower, more natural attack and release, and they tend to sound very transparent and musical. Optical pedals are popular for vocal compression in the studio, and they are a great choice if you want subtle, always-on compression that does not change your basic tone.

FET (Field Effect Transistor) compressors, like the legendary Universal Audio 1176, are known for their fast attack, aggressive character, and ability to add harmonic coloration. FET compressor pedals are rarer and more expensive, but they are prized for studio-grade transparent compression with a bit of character.

Multiband compressors split your signal into multiple frequency bands and compress each one independently. They are more common in mastering and broadcast applications, but a few guitar pedals offer multiband compression for players who want very precise control over how different frequencies respond to compression.

Where to Place a Compressor in Your Signal Chain

Compressor placement is one of the most common questions from guitarists, and the answer depends on what you want the compressor to do. The two most common positions are first in the chain (right after the guitar) or after drive pedals but before time-based effects (delay, reverb).

Placing the compressor first gives you the most consistent signal going into the rest of your pedalboard. Your drive pedals will see an even signal, which means your overdrive and distortion will respond more predictably. This is the right position for players who use compression as a tone sweetener or for chicken-pickin’ country.

Placing the compressor after drives gives you a different feel. The compressor will even out the peaks generated by your drive pedals, which can help tame an aggressive distortion and add sustain to lead lines. This position is popular for rock and blues players who want the compressor to act more like a studio engineer polishing a hot signal.

For bass, the most common position is first in the chain. This gives you even dynamics going into your drive and modulation pedals, which keeps your low end tight and consistent. The Boss CS-3 and MXR Dyna Comp both work well in this position.

Genre-Specific Compressor Settings

Different styles of music call for different compressor settings. Here are some starting points based on our testing.

For country and chicken-pickin’, use a fast attack, fast release, and a high compression ratio. This gives you the percussive, squashed sound that defines the style. The MXR Dyna Comp is the classic choice, and most players run the Sensitivity knob around 1 o’clock and Output at unity or slightly above.

For blues, use a medium attack, medium release, and a moderate compression ratio. You want the compressor to smooth out your dynamics without killing the natural feel of your playing. The Keeley Compressor Plus with a low blend setting works beautifully here.

For funk rhythm, use a fast attack, fast release, and a high compression ratio. Funk rhythm guitar is all about consistency, and the compressor should be working hard. The Keeley or Wampler with the blend set high will give you the percussive, even sound you need.

For rock lead, use a slow attack, medium release, and a moderate compression ratio. The slow attack lets your pick transient cut through, and the medium release adds sustain to your bends and vibrato. The Wampler Ego V2 is perfect for this application.

For metal, you do not need much compression at all. Your high-gain amp is already compressing the signal, and adding more compression can choke your tone. If you do use a compressor, set it to a low ratio and use it as a clean boost only.

Beginner Buying Tips for Compressor Pedals

If you are buying your first compressor pedal, keep a few things in mind. Start with a simpler two- or three-knob design. The MXR Dyna Comp, Donner Ultimate Comp, and KLIQ Tiny-Compressor are all excellent choices for beginners because they force you to learn the basics without overwhelming you.

Make sure the pedal has true bypass. Buffered and digital bypass circuits can subtly change your tone, and you want your signal to be as clean as possible when the pedal is off. All seven pedals in this guide have true bypass except the Boss CS-3, which uses a buffered bypass by design.

Use an isolated power supply. Cheap daisy-chain supplies introduce noise that compressors will amplify. A good isolated power supply will keep your compressor quiet, and it will improve the noise floor of your entire pedalboard.

Do not be afraid to leave the compressor on. Many players use their compressor as an always-on tone sweetener rather than an effect. Set the compression low, dial in a subtle amount of sustain, and leave the pedal engaged throughout your set.

Compressor Pedal Key Terms Glossary

If you are new to compressor pedals, the terminology can be confusing. Here are the most important terms you will encounter.

Attack controls how quickly the compressor engages after a transient. A fast attack (1-10 ms) immediately pulls the volume down after a loud note, while a slow attack (50-100 ms) lets the initial pick transient pass through before compression kicks in.

Release controls how quickly the compressor stops affecting the signal after the volume drops below the threshold. Fast release keeps the compression snappy, while slow release gives a smoother, more natural sound.

Ratio determines how much compression is applied once the signal crosses the threshold. A 2:1 ratio means a 2 dB increase in input produces only a 1 dB increase in output. Higher ratios mean more aggressive compression.

Threshold sets the volume level at which the compressor starts to engage. Signals below the threshold pass through unaffected, while signals above the threshold are compressed according to the ratio setting.

Makeup gain is a clean boost applied after compression to restore the volume lost during gain reduction. Most compressor pedals include a level or output knob that functions as makeup gain.

True bypass means the pedal is completely out of the signal path when disengaged. Buffered bypass uses an electronic buffer to keep the signal strong over long cable runs, but it can slightly color your tone.

Blend control (also called dry/wet or mix) lets you mix the compressed signal with your original dry signal. This is the key feature for parallel compression in stompbox form.

Parallel compression blends a heavily compressed signal with the original dry signal. The result is a fatter, more even sound that preserves the natural dynamics of your playing.

Always-on compressor is a compressor set to a low compression ratio and used as a permanent part of your tone. Most country, funk, and blues players use compression this way.

Frequently Asked Questions About Compressor Pedals

Final Verdict: Which Compressor Pedal Should You Buy?

After three months of testing, the Keeley Compressor Plus remains our top pick for the best compressor pedal for most players. It offers the best balance of transparency, control, and value, and it has earned its reputation over more than a decade on professional pedalboards worldwide. The blend control is the feature that makes it special, and it is the reason the Keeley handles every genre from country to blues to funk.

If you want a more advanced compressor with full studio-style control, the Wampler Ego V2 is the right choice. It is the quietest, most flexible pedal in this guide, and the 5-year warranty means it will be on your board for years to come. For bass players, the Boss CS-3 is still hard to beat at its price, and the MXR Dyna Comp remains the studio standard for classic chicken-pickin’ tones. On a tight budget, the Donner Ultimate Comp and KLIQ Tiny-Compressor both deliver serious value for under $40, and the JHS 3 Series offers boutique tone at $99.

Whatever you choose, remember that the best compressor pedals are the ones you actually use. A $30 KLIQ Tiny-Compressor that lives on your board and gets used every day is more useful than a $300 boutique pedal that sits in a drawer. Start with one of these seven picks, spend some time dialing it in, and let your playing guide you from there.
