Wasn't sure whether to post this here or in the tech subforum, but since it has more to do with tone, I think this is the right place.
Anyway, I was experimenting with different pickups in my PRS and since the magnet in the bridge pickup needs to be flipped in order to work with the 5-way rotary switch, I started messing with the pickup wires. Long story short, I ended up with the CS wired directly to the volume pot (bypassing the switch) and I could swear it sounded different. With BKPs, the red wire is hot and the black is ground, but I tried reversing these two wires. BINGO! That was the tone change I was hearing! With the "black = hot" the tone was clearer and bit tighter. It also seemed to bring up the mids a tad and even out the EQ response. With the "red = hot" the low end was too distorted and the low mids sounded a bit bloated in this particular guitar.
I'm not sure if I should even be hearing a difference, but in this guitar "black = hot" sound better to my ears. Anybody know what's happening tech-wise and why I'm hearing a difference? Has anybody experimented with this? I think it's definitely worth trying since it takes you about 30 seconds to switch wires.
