I hate to make anouther one of these threads, but here goes. I'm curently playing on a Schecter Diamond Seven. It's a seven string, and it only has two pick-ups, and a three way switch. Both are EMG-HZ's and the tone is okay. I was thinking about switching the two pick-ups out. I would like to have a warm sounding pick-up for the neck, and a sharper one for the bridge. Would mixing pick-ups cause problems, and do you have any suggestions for pick-ups that would fit in the seven-string cavities? Thanks.
