Guitars like the strats, mustangs, jazzmasters etc with the pick ups attached to the inside of the pick guards are among the easiest to modify but saying that, the thing you have to remember is that you can’t wire them up wrong and burn something up! It either works, doesn’t, or hums like crazy. I bought a Gibson SG at a really good price at a guitar expo and stuck in SD Antiquity Pearly Gates and now this fairly cheap guitar is my best sounding and at about $300 I bought top of the line Billy Gibbons killer pick ups. Dave, you’ve opened the door to some fun and exciting guitar times ahead, keep it going!
