Simple, Yet Works Great
Ease of use. Does not mark bass. Especially helpful for me when playing up by neck.

Satisfied with the Product
Using on a Hofner 500/1. The pickup position doesn't leave a lot of room to rest the hand. The comfort and playability are much improved with the Thumb Fin. Would give this product a 4.5 if able. Will consider addition for other basses.
Maybe explore some optional colors - black, white, silver?

Happy customer!
Ordered one of these for my Fender Fullerton P-Bass Uke as I didn’t want to drill any holes into the small acoustic body. Found this gadget online and love the simplicity of it! (Only wish I’d thought of it myself). The yellow I ordered is a great colour with my bass’ sunburst finish, and I’ve had no issues with it moving so far whilst playing (albeit practicing and not gigging). Such a super easy way to add a useful function and a pop of colour. Thanks all!
