Here is how to add a no-damage thumb rest to any Fender bass. This one is made from a piece of maple scrap and two SS screws from the hardware store. You can wrap the original screws in tape and store them in the control cavity. Walnut also makes nice thumb rests. Just a few minutes on the belt sander.

I loves me my thumb rests, I never got the hang of using the E string.
