i have an epi LP jr. and i'm considering changing the stock pickup to the vintage p90 or the SH-5 duncan custom i saw on the seymour duncan website. would it fit into the carving of the guitar? or should i just settle on the duncan custom?
G-G-G D-E-C C chord
You have to get a p90 made for a humbucker sized hole. Standard p90s dont fit. There are quite a few brands that make humbucker sized p90's e.g seymour Duncan SPH90-1 phat cat, or Bare Knuckle Mississippi Queen.
Your Lp jr. has a humbucker already (right?) so the SH-5 will fit straight in. A P90 would be cool so look around and see what humbucker sized P90's you can find.
