I can't seem to leave well enough alone. I'm always fiddling and tweaking my guitars. Even the acoustics I'll try different bridge pins, strings and the like. I have an old beater I'm going to do a neck reset, refret and refinish. Not because it needs it so much as I want to learn how and can't resist messing around with it. I'm always swapping pickups, bridges and moding my electrics. Usually nothing that can't be reversed though.
