Nice item! I like the suction cup attachment so I can put it exactly where I want with no damage to my bass.
Lots of colors available, but no purple?
With this I am off the sharp edge of a pickup, and able to hit string exactly where I want. Shipped super fast.
I ordered it and received it very quick. It sticks perfect on my sterling base.
I have a few basses I've tried the Thumb Fin out on.
It allows me to hit the sweet spot pretty consistently, and is easy to attach and detach as needed. Just have to remember to keep the suction cups clean.
I'll keep using the Thumb Fin.
Great product, allows me to experiment without making permanent changes to my Bass.
