Gary Moore has Peter Greene's old Les Paul that has a unique wiring setup. It was sent to a shop in the 60's for a repair and the tech re-wired it "wrong". It has a neat out of phase tone when both pups are engaged, he can get different sounds by backing off either of the pups and get a unique tone not normally found in Les Pauls.
I got close to the tone a few years ago with a PRS/Boss BD-2/Marshall setup. Use a neck Humbucker for thickness.
