Top 3 Picks for Best Fretless Bass Guitars

Best Fretless Bass Guitars in 2026: Quick Overview

1. Fender Tony Franklin Fretless Precision Bass – Editor’s Choice

The Fender Tony Franklin Fretless Precision Bass is the fretless I keep coming back to. Tony Franklin, the legendary session player for The Firm and Blue Murder, collaborated with Fender to create an instrument that feels like an upright and sounds like a Precision. I spent two weeks playing this bass exclusively, and the unlined ebony fingerboard rewards confident, accurate finger placement with a tone that’s both woody and articulate.

The pickup configuration is unusual: a Tony Franklin Jazz Bass single-coil at the bridge paired with an American Precision split single-coil in the middle, selected via a 3-way blade switch. This gives you more tonal range than a typical P-Bass. Rolling off the tone knob produces the classic thumpy Precision voice; pushing the Jazz pickup forward brings out singing highs perfect for melodic fretless work.

At 28 pounds with the included deluxe hardshell case, this is a serious investment. The included strap and cable are nice touches. The unlined fingerboard means there’s no visual reference for position, which forces you to develop your ear. For players transitioning from fretted bass, this can feel challenging at first, but the payoff in tone is worth the learning curve.

I noticed the unfinished ebony fingerboard feels slightly grippy compared to the gloss finishes on other models. This actually helps with tone production because your fingers make direct contact with the wood. The action out of the box was excellent, though I did adjust the truss rod slightly for my preferred low setup.

Best Use Cases and Genres

The Tony Franklin shines in studio settings where its hybrid pickup set can be dialed in for any track. Session players recording jazz, pop, R&B, and country will appreciate how quickly this bass adapts. Live, the unlined fingerboard and warm tone work for progressive rock, fusion, and any genre that values expressive playing. It’s not the right choice for slap-heavy funk or aggressive metal, where a brighter, more aggressive fretless serves better.

Who Should Skip This Bass

If you’re new to fretless, the unlined fingerboard and premium price make this a tough first purchase. Beginners should start with a lined model like the Squier Classic Vibe to develop intonation skills. Also, if you play exclusively with a pick and want bright, cutting tone, the Tony Franklin’s warmth may not suit your style. Heavy rock players seeking aggressive fretless tones should look at the Ibanez SRF700 or the EHB series instead.

2. Ibanez SRF700 Fretless – Best for Studio Versatility

The Ibanez SRF700 is what happens when a company known for modern rock basses applies that thinking to a fretless design. This bass features a mahogany body with an Okoume top, Bartolini pickups, and an Ibanez piezo system. The result is an instrument that can sound like a Precision, a Jazz, and an upright all in one session.

The 3-band EQ with Bartolini electronics gives you serious tone-shaping power. I found myself using the piezo system for ballads and slower tracks, then blending in the magnetic pickups for more aggressive lines. The extended fingerboard provides extra range for solos in the upper register, which is something most fretless basses don’t offer.

At 15.2 pounds, the SRF700 is lighter than the Fender Tony Franklin, which makes it more comfortable for long sessions. The Panga Panga fingerboard is dense and smooth, with a feel that sits between rosewood and ebony. The rolled edges are a nice touch that reduces hand fatigue during extended playing.

One issue I encountered was the 9V battery requirement for the active electronics. The preamp compartment is accessible, but it’s one more thing to remember. The piezo system produces remarkably authentic upright bass tones, which is what makes this bass special. If you need double bass sounds without the logistics of an actual upright, the SRF700 delivers.

Best Use Cases and Genres

The SRF700 excels in studios where session players need to cover multiple bass styles in a single session. The piezo system alone justifies the price for anyone recording orchestral mockups, jazz ballads, or world music. Live, this bass works for progressive fusion, jazz-rock, and singer-songwriter contexts. The extended fingerboard also makes it ideal for bassists who play in higher registers.

Who Should Skip This Bass

If you don’t need upright-style sounds, the piezo system adds cost you won’t use. Players who prefer the simplicity of a passive setup should look at the Fender Tony Franklin or the Squier Classic Vibe. Also, the SRF700 is overkill for beginners, who would benefit more from a simpler, lined-fingerboard model to develop their technique first.

3. Ibanez SRH500F Fretless – Best Semi-Acoustic Option

The Ibanez SRH500F sits at the intersection of solid body and semi-hollow design. The mahogany body with spruce top gives it acoustic resonance, while the AeroSilk piezo system captures that woody character. At 13 pounds, it’s lighter than most solid-body fretless basses, which makes it a joy to play for long sets.

Ibanez includes D’Addario Chromes flatwound strings, which is the correct string choice for fretless. The setup out of the box was excellent, with low action that made it easy to execute slides and vibrato. The Panga Panga fingerboard is dense and smooth, with a feel similar to ebony.

The active electronics with the AeroSilk system produce warm, vocal-like tones that work beautifully for jazz, ballads, and any music where you want the bass to sing rather than punch. I found the 3-band EQ useful for sculpting the tone, though the battery requirement is a minor inconvenience. The trim pots for string gain adjustment let you balance the piezo response across all four strings.

The semi-hollow body produces some natural resonance unplugged, though not enough to play acoustically. The trade-off is the lightweight feel and the unique tone. If you’re considering an acoustic-electric fretless or want the experience of a semi-hollow design, the SRH500F delivers a lot of value at this price point.

Best Use Cases and Genres

The SRH500F is ideal for jazz, fusion, and acoustic settings where its warm, woody tone complements the music. Singer-songwriter gigs and small combo performances benefit from the lightweight design and the included gig bag. The piezo system also makes it suitable for sessions that need upright-like sounds without the hassle of an actual double bass.

Who Should Skip This Bass

Players who need aggressive, cutting fretless tone for rock or metal should look elsewhere. The SRH500F’s warm, acoustic character doesn’t deliver the brightness and attack those genres require. The awkward input jack position is also a real issue for some players. If the jack placement bothers you, the Ibanez EHB series or Fender Tony Franklin have more conventional layouts.

4. Ibanez AEGB24FE Acoustic-Electric Fretless – Best Acoustic-Electric

The Ibanez AEGB24FE bridges the gap between traditional acoustic basses and electric fretless designs. With a sapele body, walnut fingerboard, and built-in piezo preamp, this bass produces genuine acoustic tone. I was genuinely surprised by how loud and full it sounds unplugged, which is rare for a fretless acoustic-electric bass.

This bass sits at the boundary between fretless electric and electric upright, making it a great option for players considering both categories. If you’re cross-shopping with electric upright basses, the AEGB24FE offers similar acoustic character in a more familiar form factor.

The 7.7-pound weight makes this one of the lightest fretless basses available. The shorter scale length feels comfortable and slinky, which is great for fretless technique. The thumb rest is a thoughtful addition that provides anchor point and improves right-hand stability.

The built-in preamp handles the piezo signal well, though some users may want to upgrade to an external preamp for more control. The acoustic tone unplugged is impressive for the size. Plugged in, the AEGB24FE sounds bright and articulate, with enough volume for coffee shop gigs and small venue performances.

Best Use Cases and Genres

The AEGB24FE is perfect for acoustic gigs, singer-songwriter performances, and folk music. The genuine acoustic volume makes it practical for unplugged sessions and campfire-style playing. Fretless technique adds expressiveness to these contexts. It’s also a great choice for bassists who want a more portable alternative to an upright bass for jazz and roots music.

Who Should Skip This Bass

If you need rock-solid tuning stability and aggressive electric bass tone, this isn’t the right choice. The acoustic character is the main feature, but it also means the bass doesn’t deliver the punch of a magnetic-pickup electric. Players who want both acoustic and electric tones in one instrument should look at the Ibanez SRF700, which has both magnetic and piezo systems.

5. Squier Classic Vibe 60s Jazz Bass Fretless – Best Budget for Beginners

The Squier Classic Vibe 60s Jazz Bass Fretless is the gateway drug to the fretless world. Designed by Fender, built by Squier, and styled after the iconic 1960s Jazz Bass, this instrument gives you the fretless experience without the premium price tag. I recommend this bass to every beginner who asks me about getting into fretless.

The laurel fingerboard with side dot markers provides enough visual reference to help you develop intonation. The Fender-designed alnico single-coil pickups produce the classic Jazz Bass voice, which works well for many styles. The vintage-tinted gloss neck finish looks great and feels smooth.

Be aware that the setup out of the box often needs professional adjustment. I sent mine to a tech for a proper fretless setup, which included leveling the fingerboard (even though there are no frets, the board still needs to be true), adjusting the truss rod, and setting the action. Once dialed in, the bass plays beautifully.

The main complaint I have is quality control. Some units arrive with sharp fingerboard edges that need sanding, and finish quality varies. At this price point, some inconsistency is expected. The good news is that 49% of reviewers give it 5 stars, which suggests more hits than misses.

Best Use Cases and Genres

The Classic Vibe is perfect for beginners, students, and players who want to try fretless without a major investment. It handles jazz, rock, pop, and country well. The 60s-style pickups work for Motown, classic rock, and indie. For bedroom players, weekend warriors, and working musicians on a budget, this is a solid choice.

Who Should Skip This Bass

Professional gigging musicians who need bulletproof reliability should invest in a higher-tier instrument. If you play shows multiple times a week and need a bass that arrives perfectly set up, the Squier’s quality control variability is a concern. Also, if you want premium tone and build, the Fender Tony Franklin or Ibanez SRF700 are better long-term investments.

6. Ibanez SR375E 5-String Fretless – Best 5-String Mid-Range

The Ibanez SR375E is a 5-string fretless that punches above its weight. With a maple body, Jatoba fingerboard, and active 3-band EQ, this bass delivers the extended range of a 5-string with the warm, vocal quality of a fretless. I tested this bass alongside several premium 5-string options, and it held its own in terms of playability.

The Jatoba fingerboard is notably hard and dense, which is good for fretless durability. Roundwound strings will eventually wear it, but Jatoba resists damage better than softer woods. The 3-band EQ provides plenty of tonal flexibility, from vintage thump to modern growl.

At 15 pounds, the SR375E is heavier than the 4-string SR models, but the weight is well-distributed. The neck is fast and comfortable, with a profile that works for both thumb-and-fingers and pick styles. The active electronics require a 9V battery, but the tonal versatility justifies the inconvenience.

My main criticism is that Ibanez ships this bass with roundwound strings, which is the wrong choice for fretless. Flatwounds or groundwounds protect the fingerboard and produce the classic fretless sound. Swap the strings immediately, and this bass transforms.

Best Use Cases and Genres

The SR375E is ideal for metal, progressive rock, and fusion where the low B string adds range. It also works for jazz and session work where the 5-string capability provides flexibility. The active EQ makes it versatile enough for modern rock, pop, and R&B. For bassists who want fretless tone with extended range, this is one of the best values available.

Who Should Skip This Bass

If you don’t need the low B string, the 4-string SR370E delivers similar tone at a lower price. Players who prefer passive electronics should look at the Fender Tony Franklin. Also, the roundwound factory strings are a real concern; if you’re not willing to invest in proper flatwounds, this isn’t the right choice for you.

7. Ibanez EHB1005F 5-String Fretless – Best Premium 5-String

The Ibanez EHB1005F represents the high end of the company’s fretless offerings. With Bartolini active pickups, Vari-mid 3-band EQ, and a 5-piece roasted maple/walnut neck, this bass is built for serious players. The ergonomic body shape is a departure from traditional bass designs, and it’s noticeably more comfortable than standard shapes.

The Richlite fingerboard is an interesting choice. Richlite is a paper composite that looks and feels similar to ebony but is more consistent and environmentally sustainable. The surface is smooth and provides a fast playing feel. The Bartolini pickups deliver detailed, articulate tone with plenty of low-end authority.

The Vari-mid EQ is a professional feature that lets you sweep the midrange frequency to dial out problem frequencies or boost specific ones. This level of tonal control is what separates professional basses from entry-level models. The 5-piece roasted maple/walnut neck is stable and resistant to warping, which matters for a 5-string with a longer scale.

At 13.7 pounds, the EHB1005F is reasonable for a 5-string. The ergonomic body shape distributes weight comfortably, making long sessions manageable. The included gig bag is a nice touch, though a hard case would be preferable for serious gigging.

Best Use Cases and Genres

The EHB1005F is built for professional gigging musicians and serious studio players. It excels in progressive metal, fusion, jazz, and any genre that demands both extended range and fretless expressiveness. The Bartolini electronics handle complex musical passages with clarity. Session players who need a versatile, reliable 5-string fretless will appreciate what this bass offers.

Who Should Skip This Bass

The price point puts this out of reach for casual players. Beginners and intermediates would be better served by the SR375E or the SR370E. The limited review data also makes it harder to assess long-term reliability. If you want proven performance, the Fender Tony Franklin has a longer track record, though it’s a 4-string.

8. Ibanez SR370E Fretless – Best Value Active

The Ibanez SR370E is the sweet spot for players who want active electronics and fretless tone without breaking the bank. The 3-band EQ provides serious tonal flexibility, and the Jatoba fingerboard is durable enough to handle years of playing. I found the brown burst finish to be one of the most attractive in this price range.

The two humbucking pickups with active EQ deliver everything from vintage warmth to modern aggression. The tone controls are responsive and musical, not just on/off switches. For players who want to dial in specific tones for different songs or styles, the SR370E offers genuine versatility.

At 11 pounds, this bass is heavier than some Ibanez models, but the weight is balanced. The neck profile is on the slimmer side, which works well for players with smaller hands or those who prefer fast playing. The Jatoba fingerboard is hard and dense, which means roundwound strings will take longer to wear it than softer woods.

The main issue I encountered was occasional hardware looseness. Tuning machines and bridge pieces sometimes needed tightening after shipping. This is a minor issue that a proper setup resolves, but it’s worth mentioning. The factory roundwound strings should be replaced with flatwounds or groundwounds for proper fretless playing.

Best Use Cases and Genres

The SR370E handles rock, pop, R&B, and country with equal competence. The active EQ makes it adaptable to different musical contexts. For working bassists who play multiple genres, this bass offers genuine flexibility. It’s also a good choice for studio work where the EQ can be used to match the bass to a specific track.

Who Should Skip This Bass

If you prefer passive electronics, this isn’t the right choice. Players who want the simplest signal path should look at the Fender Tony Franklin or Squier Classic Vibe. The active electronics add complexity and require a 9V battery. Also, the heavier weight compared to other Ibanez SR models may bother players who prioritize lightweight instruments.

9. Stagg BC300FL Fretless – Best Budget Flatwound Option

The Stagg BC300FL is the budget-friendly fretless that gets the string choice right. Stagg includes flatwound strings, which is the correct choice for fretless playing. This is unusual at this price point, where most manufacturers ship roundwounds. For beginners who don’t know they need to swap strings, this saves a step and protects the fingerboard from day one.

The alder body is lightweight, which is a plus for players who gig regularly. The rosewood fingerboard is a traditional choice that provides a warm, classic tone. The pickups are responsive and handle both fingerstyle and pick playing with equal competence.

The semi-gloss natural finish looks clean and professional. The hard maple neck is sturdy and provides good sustain. At this price point, you can’t expect premium hardware, but the stock components are functional and upgradeable.

My main concerns are quality control variability and the soft wood construction. The basswood body is prone to dings and nicks, so gigging players should handle it carefully. The pickups can be noisy in high-gain situations. Despite these issues, the value proposition is strong: a playable fretless with proper strings at a fraction of the cost of premium options.

Best Use Cases and Genres

The BC300FL is ideal for beginners, students, and players on a tight budget. It handles jazz, Motown, classic rock, and folk music well. The flatwound strings give it a vintage character that suits older styles. For practice, lessons, and casual playing, this is a great entry point.

Who Should Skip This Bass

Professional players need more reliable construction. The quality control variability and soft wood body make this a poor choice for working musicians who need bulletproof instruments. If you’re gigging regularly, invest in a higher-tier option like the Squier Classic Vibe or Ibanez SR370E. Also, the limited tonal range may frustrate players who want modern, aggressive sounds.

10. TARIO 5-String Fretless – Best Budget 5-String

The TARIO 5-String Fretless delivers genuine 5-string capability at a price that seems too good to be true. The Millettia Laurentii top with Okoume body is a wood combination you don’t expect at this level. The fit and finish impressed me out of the box, and the satin oil finish feels smooth and professional.

The active/passive electronics with Belcat pickups provide tonal flexibility. The 2-volume, 3-tone control layout gives you precise control over the sound. The 34-inch scale length is standard for 5-string basses, which means proper string tension and intonation.

The composite ebony fingerboard with inlays provides visual reference for position, which is helpful for players new to fretless. The two-truss-rod design is a professional feature that provides better neck stability than single-rod designs. The included padded gig bag is a nice touch at this price.

However, there are real concerns. The pickup headroom for the low B string is limited, which means the B can get muddy in the mix. The factory electronics are inconsistent in quality, and some units arrive with loose preamps. The abrasive factory strings should be replaced immediately.

Despite the issues, this bass is an excellent modding platform. Players who want to upgrade pickups and electronics can do so for less than the cost of a premium 5-string. If you’re willing to put in some setup work and potentially upgrade components, the TARIO 5-String offers tremendous value.

Best Use Cases and Genres

This bass works for players who want to experiment with 5-string fretless without a major investment. It’s suitable for rock, metal, and progressive music where the low B adds range. Modders and tinkerers will appreciate the upgrade potential. For casual practice and learning, it delivers the experience at a fraction of the cost.

Who Should Skip This Bass

Professional gigging musicians should invest in proven options. The quality control variability and electronics concerns make this a risky choice for working players. If you need a bass that arrives ready to gig, the Ibanez SR375E or EHB1005F are better choices. Also, if you’re not comfortable with potential setup work and upgrades, a higher-tier instrument will save you frustration.

11. Kala Solid Body U-BASS Fretless – Best Short Scale

The Kala Solid Body U-BASS is unlike any other bass on this list. The 23.5-inch scale length is roughly the same as a ukulele, which makes it the most portable fretless available. At 5.5 pounds, it’s also the lightest. This is the bass for players who want fretless tone in a package that travels easily and doesn’t strain your back.

The short scale produces a deeper, more upright-bass-like tone than a standard 34-inch scale. The stainless steel strings are thick and produce a rubbery, fundamental-heavy sound. The closed-gear tuners with 1:18 ratio provide reasonable tuning stability, though they’re notably stiff to turn.

The tobacco burst gloss finish is beautiful and gives the bass a premium look. The Okoume body is lightweight and resonant. The included gig bag and truss rod adjustment tool are thoughtful touches. For travel, small gigs, and practice, the U-BASS delivers genuine fretless character in a unique package.

The main issues are the stiff tuners and the soft fingerboard material. The tuners are hard to turn, which makes quick tuning adjustments frustrating. The soft fingerboard is susceptible to wear from strings, so regular maintenance is essential. The very limited stock also makes this bass hard to find.

Best Use Cases and Genres

The U-BASS is ideal for travel, camping, beach performances, and small acoustic gigs. Its short scale and lightweight design make it perfect for players who want a portable fretless. The tone works well for acoustic duos, folk music, and world music. It’s also a great choice for bassists with physical limitations who find full-size basses uncomfortable.

Who Should Skip This Bass

If you need the punch and clarity of a standard-scale bass, the U-BASS’s short scale won’t deliver. The tone is fundamentally different from a 34-inch scale, and not all genres benefit from the rubbery, deep character. Players who want traditional fretless tone should look at the 34-inch scale options. Also, the stiff tuners are a real issue for players who change tunings frequently.

12. Sawtooth Rudy Sarzo Signature Acoustic-Electric – Best Signature Model

The Sawtooth Rudy Sarzo Signature Fretless brings the legendary Quiet Riot and Ozzy Osbourne bassist’s design to an affordable acoustic-electric format. The flame maple body with hand-rubbed satin violin finish is striking. The 34-inch scale and Fishman Presys II preamp make this a serious instrument, not a gimmick.

Rudy Sarzo designed this bass to capture the double bass tones he used extensively throughout his career. The Fishman Presys II preamp handles the piezo signal with clarity, and the onboard tuner is a useful feature. With flatwound strings, this bass produces remarkably authentic upright-like tones.

The flame maple dot inlays are a nice aesthetic touch. The 12-inch fretboard radius is comfortable for both chordal work and melodic lines. The 43mm bone nut provides good string spacing for fingerstyle playing. At 34 inches, the scale length is standard, which means familiar feel and tension.

The main issues I found were the tuner battery drain and the need for setup. The onboard tuner doesn’t auto-off, which means you need to disconnect the battery when not in use. Some units arrive needing truss rod adjustments. The acoustic volume is modest; this bass really needs amplification to shine.

Best Use Cases and Genres

The Rudy Sarzo Signature is ideal for rock ballads, acoustic performances, and any music where you want the bass to provide upright-like character. It works well for singer-songwriter gigs, small combo performances, and session work. For fans of Rudy Sarzo’s playing or anyone who wants an acoustic-electric fretless with character, this is a solid choice.

Who Should Skip This Bass

If you need loud acoustic volume without amplification, this isn’t the right choice. The Fishman Presys II system is good, but the passive acoustic output is modest. Players who want both acoustic and electric tones in one instrument should look at the Ibanez SRF700, which has magnetic pickups in addition to piezo. Also, the tuner battery issue is a real annoyance for players who forget to disconnect.

13. TARIO 4-String Fretless – Best Ultra-Budget Starter

The TARIO 4-String Fretless is the most affordable way to get into fretless bass. At the price of a budget fretted bass, you get a genuine fretless with a solid build. This isn’t a toy; it’s a real instrument that can serve beginners and experimenters well.

The basswood body with maple neck and composite ebony fingerboard is a standard combination. The bolt-on neck construction is solid and the action out of the box is reasonable. The composite ebony fingerboard has a nice feel and provides durability that natural ebony can’t match at this price.

The soap bar pickups are functional but uninspiring. They produce a muddy, quiet signal that needs replacement for serious playing. The factory strings are terrible and should be swapped immediately. The knob configuration (2 volume, 2 tone) is slightly unusual but not difficult to master.

At 11 pounds, this bass is heavier than expected. The dye on the fingerboard can come off on your fingers, which is messy but not a functional issue. Despite the flaws, the TARIO 4-String is an excellent starting point for players who want to try fretless without committing to a more expensive instrument.

Best Use Cases and Genres

This bass is ideal for absolute beginners, players curious about fretless, and tinkerers who want a modding platform. It handles practice, lessons, and casual playing adequately with proper setup and string upgrades. For anyone who wants to experience fretless tone at minimal cost, this is the gateway.

Who Should Skip This Bass

Anyone who needs a gigging instrument should look elsewhere. The cheap pickups, poor factory strings, and quality concerns make this a practice and learning tool, not a working instrument. If you know you’ll stick with fretless, invest in a higher-tier option. Also, the heavy weight is a concern for younger players or anyone who values lightweight instruments.

Buying Guide: How to Choose the Best Fretless Bass Guitar

Choosing a fretless bass requires different considerations than a fretted bass. You’re not just buying an instrument; you’re committing to a playing technique that demands precision and ear training. Here’s what matters most when shopping for the best fretless bass guitars in 2026.

Lined vs Unlined Fingerboards

Lined fingerboards have fret-line markers painted or inlaid on the fingerboard surface, giving you visual reference for position. Unlined fingerboards have no such markers, which forces you to rely entirely on your ears and muscle memory. Beginners should start with lined fingerboards to develop intonation skills. Experienced players often prefer unlined for the purer aesthetic and the deeper commitment to the fretless experience. The Fender Tony Franklin uses an unlined ebony fingerboard; the Squier Classic Vibe has side dots for reference.

Roundwound vs Flatwound Strings

Roundwound strings have a bright, aggressive tone but their textured surface wears fretless fingerboards over time. Flatwound strings have a smooth, mellow tone that’s gentler on fingerboards. For most fretless playing, flatwounds or groundwounds are the correct choice. The Stagg BC300FL includes flatwounds; many other basses ship with roundwounds that need to be replaced. Budget for a quality set of flatwounds as part of your purchase.

Active vs Passive Electronics

Passive electronics use the natural output of the pickups with simple tone controls. Active electronics use a battery-powered preamp to boost the signal and provide EQ controls with more range. Active systems offer more tonal flexibility but require a 9V battery and add complexity. Passive systems are simpler and more reliable. The Ibanez SR370E and SR375E use active electronics; the Fender Tony Franklin and Squier Classic Vibe are passive.

4-String vs 5-String Decision

Four-string fretless basses are the most common and cover most musical situations. Five-string basses add a low B string, which extends your range downward. If you play music that requires the low B (metal, progressive rock, modern worship), a 5-string is worth considering. If you play jazz, Motown, classic rock, and pop, a 4-string covers everything you need. The Ibanez SR375E and EHB1005F are 5-string options; most others on this list are 4-strings.

Fingerboard Maintenance

Fretless fingerboards require regular care. Clean the fingerboard after each playing session with a soft cloth. Apply fingerboard oil (lemon oil for rosewood, ebony oil for ebony) every few months to prevent drying and cracking. Avoid roundwound strings when possible to minimize wear. If the fingerboard develops grooves from years of playing, a luthier can level and re-surface it. The TARIO basses with composite ebony fingerboards require less maintenance than natural wood fingerboards.
