My only attempt at DIY was a complete a disaster. It started when I when I wanted to change the cheap Chinese jack installed on a cheap Epiphone Dot because it had shorted out. First, problem, working with a hollow body is a *****. To make matters worst I decided to replace the pickups, volume and tone pots--two each-- and rewire everything. Soldering ground wires on the back of the volume pots turned into one of the most aggravating things I ever did in my life (and believe my wife keeps me busy). Why can't they include a loop specifically for grounding on these things? To this day after spending more on parts than the damn guitar is worth it makes a nice wall deco. I will never attempt to do that to one of my better guitars. About the only thing I will do is polish them and adjust the truss rods. Kudos to all of you who know what your doing. I'm really impressed.
