Ok, I bought a Peavey Roto EXP. great guitar, but the pickups are a bit too weak.

Should I put the PAF Pro ('89 model, so it's old) into it at the neck?

Will it be better than the Peavey high output on there?

The PAF is noisy in my Squier (picks up monitors etc., the Rotor doesn't), so will it be noisy in the Rotor too?
Sell BOTH on ebay (seriously) and get yourself either EMG's (many) Bare Knuckles, Swineshead, Lindy Fralin, Seymour Duncuns or Dimarzio's.
