I switched a screamin demon pu out to a pealy gates pu, The screamin demon had no trouble bringin out the harmonics on the g,b, and high e strings, but the pearly gates while it has made the low e,a,and the d string pull harmonics alot easier. The high ones have become really hard to pull out. could this be the fact that the screamin demon is a humbucker and the pearly is a trembucker? this is the only difference I can come up with. feed back please!!
