So I bought an electric bass guitar and I was used to put my thumb in the wide pickups of my old bass. This one have this basic thumb destroyer ones so Fippity Jippity I make a thumb stand to bass it up like it supposed to.

This thumb rest is for the precision bass only, from Fender to china made, the same screws on the pickguard hold the print.

enjoy!
