from single coils P-90's on a Epi Casin they tend to pick up noise and I know this was the case but occasional popping and that makes me nuts. There is nothing wrong with them I have had two techs go thru it but I know humbuckers pick up none of that. I am wondering if I ws to change out the P-90's on my Casino a Hollow body to humbuckers. I bought the Casino for Blues and want to maintain that sound but Classic rock flexibility as well. I do love the Casino sound but not the crap the pickups pick up. I play a SG with humbuckers and its rippin.
