Just bought a pair of mini humbuckers for a project bass. Once fitted, the one at the bridge sounds fine, but the one in the neck only has about half the output.
They measure the same d.c. resistance, so I assumed the obvious, that one coil was reverse phase, so I flipped it, about the same, or slightly worse!
It seems to have about the same magnetic pull as the good one. The pickups look similar to Hofner staple type, I wonder if there are 2 magnets inside, and one is the wrong way round?
I haven't opened it up yet as the cover is soldered on, but it will probably come to that soon.
Anything else I've not thought of?
