Just tear that one up and then buy a new one, it's expendable; look at it as mileage, the secret weapon is in your hands and what comes out of your enormous brain
The problem with SB-1s and SB-2s is that the pickguards are unique and you can't just grab one off the rack.
I have a chewed up SB-1 guard that I may try to use but the jack area is shot. I'll have to swing by my techs shop and see what he has that I can work with.
I got pots and caps to make kinda like a Jazz control area to swap in for experiments.
I have 2 other basses needing work, bad jacks, shielding etc, before the experiments begin.
