Collection: Bass Thumb Rests

Thumb Fin is a patented suction-cup bass thumb rest that you can add without drilling, screws or adhesive. Choose the Original, our tallest profile; the Low Profile, 4mm lower; or the Contoured Low Profile, 4mm lower with more concave sides. Each comes in six colors and mounts in seconds on gloss finishes and pickguards.

Playing a matte or satin bass? Add our contact paper for a surface the suction cup can grip. Not sure which shape fits your hand? The Combo 3 Pack includes one of each.
