Hi Dave and welcome to the forum, it's a bit slow down here in this section.
I know a lot of folk pay way to much (IMHO) for pups re-wires etc for their instruments and always seem to be searching for that "Illusive Sound". Gets very expensive, and for some impossible to remember what the guitar sounded like in the first place. Personally I would take your guitar to a decent shop, and ask to try out a few different amps to see how it sounds through various models. As silly as it seems, I finished up buying a cheap second hand Peavey Amp which to my ears, made the guitar sound great in most settings. I paid what one good pickup would cost, and saved a lot of chopping and changing of parts in the search for personal sound.
