I have an epiphone casino coupe (along with my teles), it is a MIC one, and the stock neck P90 is way muddy and boomy. So I have been looking on replacing them and I wanted to put a Gibson one in there but the proble. Is the pole spacing of the neck is 48mm instead of 50mm and there is nobody making a short angled dog ear cover in chrome so it was kind looking like either some custom rewinds or by some frailins and replace both because frailin covers are black, but those options cost me some coin, over half of what the guitar cost new. Plus I already am putting some coin in upgrading all the electronics to switchcraft and CTS vintage taper pots with orange drop capacitors and treble bleed (500k pots and .022 for the caps) So I decided to check the DCR of the stock epiphone pups and lo and behold the DCR for both is 12.5k so that explains the boomy dark muddy neck pup and why it overpowers the bridge. So I decided to see if I could peel some windings off it and get to a more Gibson like value and get rid of the mud that way. So I pulled 1500 windings off the neck and dropped the DCR to 9.6k a little hotter than a stock Gibson, and I thought about changing magnets but I decided that the original A5 would be the best choice for getting the most hi's out of the neck. Now I though I better do a little something to the bridge so it would work with the neck pup as far as output goes and I pulled 500 winds off and ended around 11.5k and I think that will work well. But the big question now is I am thinking about swapping one of the A5 mags in the bridge with a ceramic to give it a little more punch and snap to go with the added top end that pulling the windings will give me, and I was wondering if anyone has messed around with mag swaps on a P90, or if anyone has some experience with peeling windings and what results they had.
