Guys, I play a Sterling ray 4. The position that I get the sound I like is 1/2 way between the base of the neck and pickup. I want to add a thumb rest in this position. I hate to screw one on. Double stick tape will eventually turn loose plus does not look as good. Bass has a black pickguard & I have a black thumb rest. Its not like i am adding one to Fodera. Thoughts?
