Contact paper is used for matte finished basses. It will provide a non-porous surface for Thumb Fin to attach to. Contact Paper can be removed without leaving residue on the surface.

Easy to use! Just peel off the backing and place where you want on the bass!

I have tested it on a 1/100 Ball Family Reserve bass, so I trust that it doesn't damage the surface.

Complete your setup

Three steps, no tools

Most thumb rests mean drilling into your instrument. Thumb Fin doesn't.

01

Clean the surface

Wipe the spot and the suction cup with a soft cloth. Matte finish? Apply the contact paper first.

02

Press it on

Place it where your thumb naturally rests and press firmly. Move it anytime: no screws, no adhesive.

03

Play, relaxed

Your thumb rests in a relaxed, natural position, so you can focus on your playing, not your hand.

Bass thumb rest FAQ

Will Thumb Fin damage my bass?

No. Thumb Fin mounts with a suction cup, so there's no drilling, no screws and no adhesive. It comes off without leaving a mark, and you can move it to another instrument anytime.

Does it work on matte or satin finishes?

The suction cup needs a smooth, non-porous surface. On gloss finishes and pickguards it sticks directly. For matte or satin finishes, apply our contact paper first to give it a surface to grip.

Where should I put my thumb rest?

Wherever your thumb naturally rests while you play. Many players mount it on the pickguard. Because it's suction-mounted, you can try a spot, play for a while, and move it until it feels right.

Which version should I choose?

The Original is the first Thumb Fin shape and our tallest profile. The Low Profile sits 4mm lower. The Contoured Low Profile is also 4mm lower, with more concave sides. Not sure? The Combo 3 Pack includes one of each.

Does it work on guitar too?

Yes. Thumb Fin works on bass, guitar, ukulele and more. Anywhere with a smooth surface where your thumb wants to rest.

How do I keep it holding well?

Wipe the spot and the suction cup clean, then press it on firmly. If it ever starts to lose grip, clean both surfaces again and re-press it.
