First off... Mods, if this isn't in the right spot, please move it on out. I just *inherited* another Conklin GT-5. This is the newer model with the Bart MK-1 pickups, and the Mighty Mite (I believe) pre. Well, I'm getting an annoying buzz from it. It's not a ground issue, it's pretty permanent. As some of you might know, I have another GT-5 that had noise problems and I swapped out the pickups and electronics for USA Barts, and an OBP-3. HUGE improvement, and I love it. Anywho, I'm curious where said buzz might be coming from. I've heard some people say that the MK-1s are actually purdy good pickups, with more of a dirtier sound than the warmer USA Barts (which is fine by me). I'd go ahead and keep them and just swap out the guts for an OBP-3 if tone-wise that is the case, and they aren't to blame. So... two part question. 1.) Where is my buzz most likely coming from? and 2.) If general consensus is that the electronics that are to blame, would it be a good idea to keep the MK-1's in place, and just swap the pre? Thanks much in advance!
