I bought a beat-to-crap old MM around 10 years ago, and it's just been sitting in my studio. The finish was mostly sanded off of the body, it was covered in newspaper comics, the bridge was replaced, tuners are different, no P90, etc. Looks like somebody decided to be creative with it in the 80s. The latest price guide says an excellent condition model would be worth around $900. It looks like utter poop and I'd like to restore it *if* it would be worthwhile. Should I even bother?
