I just bought a Schecter Revenger 7 string on Ebay, and I want to replace the pickups. Currently it has Duncan Designed, and I want to replace them with the Dimarzio Air Norton 7 and the D Sonic 7. I've heard that Dimarzios sometimes don't fit guitars that came with Seymour Duncans without some routing, which I'd like to avoid.
So my question is, how do I figure out if I'll have a problem installing the new pickups without having everything in front of me? I was planning on ordering the Dimarzios online and I don't want to get stuck having to ship them back for something else.
Usually, it works the other way around, since Dimarzio uses triangle tabs, and Duncan uses square (which are bigger). Every time I hear about a fitment problem, it is someone trying to put non-Dimarzios into an Ibanez. I bet they'll fit your guitar just fine. If not, a little filing will do the trick.
