Guild M-75 response
I have one of these from early 70's, mine has the master volume, and phase switch. These are great guitars, and won't kill your shoulder after a full night gigging!
I did some changes to mine, though the original Guild pickups are excellent, mine came with a Seymour Duncan of unknown vintage in the bridge position, one of the coils was open, and the pots were scratchy. I took all the electronics out, and completely re-did everything, pots, wiring, tone caps, everything. I put a Kent Armstrong P90 on the bridge, and a DeArmond goldtone humbucker on the neck, and re-wired the mini-toggle for series or parallel operation for the Dearmond.
Blues spoken here!
This was not a collector grade guitar to begin with, but for sure is now one of the nicest players I own.
