I have several BK rewinds
Original 60's Strat - the coil was fraying and the pickup had shorted, so Tim rewound it and I can't tell it from the originals (really - i can't remember which position I put it in and when you play it is impossible to tell).
1960 P-90 - this had a broken bobbin (a common P-90 problem), so BK fixed it with a new one, but I had an AIV magnets rather than the A5. The magnet change wasn't quite as successful as I would have liked as the output dropped quite a bit. The pickup sounds great but I will probably go back to the original magnets.
Original Gibson PAF. This had been overwound on one coil with a different type of wire. Tim rewound it back to stock with the correct wire. It is like a Stormy Monday and has a great old Gibson tone.
I would reccomend the rewind if you have a pickup that is broken. If you want to change the tone of the pickup I guess it could be done within reason.
