Can't do "out of phase" (is this the same at phase reverse?) on an EMGed mustang? I always figured mine was. When I set my switches away from each other or toward each other I get the same nasaly, springy sound I've gotten from other mustangs.
Now that I think about it, I'm unsure if it was an EMG logo I scratched off or a lace sensor logo or a "noiseless". It was 12 years ago! I can still remember doing it, but can't remember exactly what they were. I just knew it didn't look right but it sounded right.
I can say that the letter were just printed on the blastic in small white ink and came off easily. They weren't etched into the surface or engraved or raised up. I can't say what they were. Just some kind of single coil.
