V8 Sorry, I might not have expressed myself clearly. I have one guitar with normal-sized humbuckers, and I will be getting another guitar that also has normal-sized humbuckers. Thus my thinking to change the new one into something with P90ish or Singlish pickups (in sound only, I'm not entertaining the idea of routing the body cavities).
I like the filtertron idea, are they standard humbucker-sized?
