gonna swap out the hum buckers in the minijazzmaster with gfs surf 90’s next week. annoyingly there is wiring ambiguity, three wires, white, red, bare, the diagrams on the gfs site show white, red, black. can deduce the bare one is the black one but don’t really know for sure.
gfs pickups now have quite a good thing where once you have soldered in the wires, you can detach the pickup and slot any of their others in, making it really easy to try out different ones. they have loads i’d give a go, gold foil, lipstick, filtertrons. they are about as cheap as it gets, but the surf 90s are great, so might give some others a shot
