Hey guys, I've had my black BC Rich P7 Warlock (i.e., this model) for a couple of years now. I bought it second hand for very little money; it was my first 7-string and I still like it very much, despite the fact that it's obviously not the fanciest guitar in the world. I'm thinking about doing a little maintenance and fine-tuning on it and maybe upgrading it in some way. What would be the most useful and efficient thing to do / have done that would improve tone or playability without costing too much? I'm thinking one or two new pick-ups perhaps: would that be worth it or would it be like putting a V8 engine in an old Citroën 2CV? Any suggestions on pickup models? As you may have noticed, I'm not a huge expert on guitar tech (or cars, for that matter).
