I've got an Ibanez RG 652, and it's quite possibly the most perfect guitar I've ever owned. Except for the pickups. They are DiMarzio Fusion Edge. They are not in the DiMarzio catalog, but online sources say they are roughly equal to the Titan. They're not bad, and I could live with them, if they didn't turn muddy under distortion. I have a SH5 custom in a different RG that I absolutely love, and the knee jerk reaction is to put one in here. The problem is, this RG has an ash body, and I've heard many people say that the Custom doesn't play well with brighter woods. Custom 5 maybe ? Thinking of a 59 for the neck either way. Opinions ? Options ?
