I want to replace the pickguard on my Peavy Milestone II which is a basic P-bass. Can I simply use any P-bass pickguard, or do the makes differ slightly? The reason is I can find Fender pickguard replacements abundently, but have rarely seen anything for Peavys, let alone the Milestone II. Also, anyone know anywhere (website) that has these pickguards? I'm looking for a brown or black one...thanks guys!
