Need early M-85 wiring diagram

[mmmalmberg]

I'm re-wiring my M-85, which I'd previously wired about 30 years ago but without a legit reference, and with a humbucker in place of one of the single-coils. I'd like now to get it back to original as closely as possible.

It has two single-coil pickups, 2 vol. & 2 tone pots and a pickup selector switch. I think I'll replace the pots and caps while I'm at it so I need correct values for those as well. If anyone can point me to any of this information I'd be very grateful!

Thanks
Mark M.

What is an M-85?

Sounds like standard Les Paul wiring, in any case.

Thanks for your reply. The Guild M-85 is a bass from the late 60's -early 70's.

The earlier ones like mine have a deep "semi-solid" or "semi-hollow" body somewhat like a Les Paul in shape but nearly 3" deep, and have Hagstrom single-coil pickups, the ones that Darkstars are based on. Mine appears to have a maple body and mahogany neck from what I can tell, under black paint and white binding.

The only wiring access is through the pickup holes.

Someone at Guild (Fender) tentatively confirmed the Les Paul circuit concept. They don't have the diagrams so he was guessing, suggested 250K pots. Not sure what caps were stock so I guess I'll use .047uF.
