I have owned this bass for a while and can't imagine what it was like not to have owned it. The growl of this bass is distinct even from other warwicks; also, you can get a growl no matter where you go on the fretboard. It's incredibly punchy but still with enough bottom end beef. Overall this is an excellent bass, it sounds just as good as some more exspensive basses. I have people all the time asking me what kind of wood it's made out of and how Exquisite it's looks are.


warwick thumb fretless

Great bass right out of the box. I put rotosound flatwounds on it. The sound was just what I was looking for. Thank you warwick!


It's cool

Features are awesome! The neck that goes through the entire guitar is cool. Sound is deep and precise.


duh, its a warwick

come on, warwicks are the best. i love their thumbs man. its like a musical heaven in your hands. and to that dumb guy below me... fretless basses aren't supposed to have frets. it gives them a unique tone, and sounds great wen doing slides. the only thing is its harder becuz you have to play right where the fret SHOULD be.


Warwick Thumb BO Fretless 5-string

By Totsh

from Germany

If you need a fretless that growls like a wolf and can sing like a whale - try this bass!The Ovangkol body and neck has very delicate harmonic resonance. The lows are very clear, the upper mids and highs are well defined - be the backbone of your band or jump to the frontline and blow the people away with a great lead-bass-sound. The pickups provide a broad range of sound textures.The deep brown oil finished wood feels just like velvet and is looking great. The polished ebony-fingerboard is not just good looking, it plays like a dream. The possible adjustment (bridge-, nut-, and saddle-height, string-spacing, trussrod) will definetly meet your needs. Think of a Warwick as a Mercedes or maybe a Porsche amongst the basses - the quality concept "Made in Germany".A slight drawback is the weight of the bass (ca. 3.7 kilos) and the electronics cover - the tabs of it can break to easy.


One of the best basses created

It's all around awesome, good tone, good feel, good everything. Plus its got a bass boost which is awesome if u play funk/metal or metal...or funk.

First thing that amazed me was the incredible highs. That fretless "mwah" opens some crystal-clear notes. Down low, there really is a "warwick growl". Yeah, at first i was skeptical of that overused phrase too, but man is it accurate. Fantastic neck thats easy to move over and get precise tones. The range of sounds you can get from messing with the treble/bass knobs is a great feature, but it would have been better if an extra "mid" knob had been added, or if the pick-up select knob had more effect. Overall, incredible instrument.


Warwick, they're the best

By bassthug20

from Crescent City, CA

I have the thumb bolt on, have had it for over 2 years, couldn't imagine getting rid of it. Whenever I got to a music store and play a different bass it just doesn't feel right. The sound is awesome, the look is great, and the playability is the best. All in all, if you have the money I wouldn't hesitate in buying it.

I loved it was great...i owned many other fretless basses and Warwick puts out the best ever...any bass by warwick is great. Great sound, tone, easy to play and you get your money worth.


Best bass i had ever played

By warwickskickass

Both electronics and wood make the best combination for any style of music. This was the best money I had ever spent ever on anything.


The one bass you need

By Günter Haika

from Austria

Bought some, sold some. But I'll definitely hang on to this one.
(My arsenal: Warwick Thumb for fretless, Modulus VJ4 for fretted. All others don't get used much.)
Got the SE version with passive Bartolini J-PUs and active MEC electronics, Ovangkol body. Before I found this bass, I tried a Corvette fretless with Humbuckers, which has many more sound options, but I wondered who'd ever need those? Then I tried this one: the sound is just right, the stacked 2-way EQ control knob gives just enough tonal variety for me. This bass sounds great, nice growl, lots of power. Action out of the box was higher than expected, but easily playable, so I left it. And yes, as some forum posts indicate: the neck likes to dive. Buy a good, wide leather strap, and tis is not a problem.
Any other noteworthy features? Oh, right: NO FRETS! (It IS a feature!)
Heavy, flawlessly crafted, beautiful wood. Feels indestructible.
Got a great deal on mine, but even MSRP is ok for this quality instrument.
