Most of mine are stock, or pretty close. Since I really have only bought used guitars (with only a few exceptions), I bought them chasing something in particular. That something would usually be some sound I was looking for with particular stuff I had in mind with bands I was playing in at the time. Rare exceptions being my taste in sound changing over the years. '60s SGs with DiMarzio Super Distortion pickups were always cheap, and they had a good crunch to them. As I bought better amplifiers, I realized I liked the sound of low output '50s PAF style pickups better, and made the swap. The same goes for my '85 Les Paul that sounded terrible with the Shawbuckers in it. That also now has '59 spec pickups in it. Otherwise, most of my guitars are as exactly as I bought them.
