I want to eventually replace a MII Squier affinity J of mine, that I'm keeping at my high school band room, and I didn't want to go overboard and figured I could get a good MIM J bass, used for around $500. However I'm a HUGE Led Zeppelin and John Paul Jones is my favorite bassist (and the best ever IMHO). I was wondering if I could eventually modify this bass to give the appearance of his '62, however I'm wondering what I would need to do for that. I know the '62s were supposed to have stacked knobs, however I've seen pictures of him with stacked knobs and without? What did his '62 look like? and if so, could I effectively turn a stock MIM standard J bass into something similar to what he used ( I would eventually modify the pickups, to if possible vintage Fenders)? Also did he play his '62 on Heartbraker? It's in my opinion the LZ song that I enjoy the most, so it's what gave me this idea.
