I bought this pickup set for a future project, but I made some observations and measurements that might be helpful. I was pleased with the robust construction for such an inexpensive pickup, even the lead wires are 22 AWG. The coils measure around 7.25K ohms with 3.25H inductance. Testing with a tuning fork confirmed the high output suggested by those measurements. Not noticeably noisy, but I would at least twist the lead wires and potentially do some shielding when installing. (It is a single coil, after all) Incidentally, the white wire is hot and some contact noise will appear if it is wired in reverse polarity. All in all, a lot of bang for the buck.
