Hey, well, this has been a long time coming but my Jaguar refinish is on its way to completion. My plan is to toss the preamp and wire it passively. However, I'm adding a Rickenbacker HB1 (humbucker) between a set of Dimarzio Model Js. I want to set it up so the three switches are neck/middle/bridge on-off, and the former active/passive switch becomes the series/parallel. Here goes, forgive me. -Setting up all three pickups so they can be switched between series/parallel...wait, can this/would I even want this done? Won't the J pups sound better parallel and the HB1 series? Would I then be better off disabling the HB1 and use the Js if I want to switch between series/parallel? ...this question is a train wreck. -About the volume pot -- since by default it is one volume, one tone...is there any reason why I couldn't use a stacked volume pot and have it wired so the J pups use their own control and the HB1 uses the other? I'm concerned about balancing the output of the pickups and this seems like a good way to manage it. Do they even make 500k stacked volume pots? Does this sound needlessly complicated? What am I overlooking?
