If you're looking for a non-mod and easily adjustable thumb rest, you can't go wrong with Thumb Fin. I've been using it for up to a week now and I haven't had any issues with the suction cups. I highly recommend this!
I am a newbie bass player (at 66) so I haven't really settled into the best thumb position yet. The suction cup adhesion method (which holds very well) of Thumb Fin allows me to move around a bit to find the best location and angle for me without drilling holes or otherwise marring my guitar. I am very happy with the purchase.
This type of attachment using plungers works really well on a shiny surface and on a pick guard. But it does not work on a matte finish bass guitar or a bass guitar that is stained. If there are any solutions to this dilemma, please let me know
Incredibly cool gadget. We all need somewhere to put our thumb when plucking, and that’s not ideal on like 90% of bass pickups - this lets you post up where you’re comfortable. Surprised by how sturdy this is for plastic suction cupped to a pickguard, really feels stable. Have and will continue to recommend to friends.
2 quick requests, it would be awesome to put a little lip/ledge on one side so my thumb won’t slip if I sweat, and wooden ones to match a fretboard would be AWESOME
Fantastic product! Holds great, easy to remove if I choose and won't damage my bass!
