I'm building a Fender clone P/J using Peavey forum pickups and pots. I picked a trashed early '90's Peavey forum and scavenged the keys, pickups and electronics, and am going to use them in my P/J build, but really dont know what I have here. The Pbass pickup looks pretty standard, but the Jazz pickup is actually a split design housed in a Jazz cover. They sounded great on the Forum bass but the neck had a busted truss rod, and was hopelessly warped Are they both humbuckers? are the pots 500K? One of the pots is scratchy and I want to replace it, or maybe go with Volume/tone concentrics. Any info out there on these pickups/electronics? Or any suggestions on replacing the pots?
