I say tear that sucker apart and do whatever it takes for it to sound right. A guitar is nothing more than a tool used to get a job done. When I got my 1969 Silvertone from some jackass Ebayer who beat the living shit out of it (several cracks in the headstock and the body itself beneath the pickguard where you can’t see it) I was not surprised when there was intermitant tonality and static from bad pots. The tuners were also bad so I had to make a choice to either accept playing out of tune with shitty tone (keeping the guitar in its original ‘vintage condition’), or mess with the wiring and replace the tuners in which case I would need to permanently modify what once was possibly a re-sale valuable vintage guitar. Sure I felt guilty at first, drilling out bigger holes in the headstock- but that feeling evaporated quickly once I bypassed all those crappy volume & tone pots and jammed with a freakin’ awesome sound that’s at least a hundred times better. Then I even went a step further and took one of the pickups I wasn’t using and silicone glued it into a cheap ESP guitar and it sounds great. So by treating my guitars as they should be, a piece of electronic equipment, I ended up with two awesome sounding guitars whereas before I had none.
