So I've been messing around with my LP a bit more, recently, gearing myself up to put some BKPs in it. Besides the issues with the G-string tuning peg that doesn't seem to go away no matter what I do with the strings, I seem to have some funkiness in the electronics, perhaps a loose connection in the pickup switch. The switch itself seems to swivel a bit more than desireable (i.e. at all), and I get a very fearsome hum/buzz when the gain goes up.
OK, I know I'm always going to get a certain amount of noise at higher gain, and yeah, moving closer to or farther from the computer has an effect. But the buzz/hum from my LP is much more noticeable than from the single coils on my bass, which is surely wrong (yes, I did try cranking the gain on the bass to guitar levels :twisted:). The buzz is pretty bad with the bridge pickup selected, slightly less bad with the neck pickup (because of the lower output, presumably), but least obnoxious with the switch in the middle position.
Anyway, that loose switch is surely not right, and I wonder if something like a grounding wire has come loose with it? I'm no electronics expert, though! :? I suppose the best thing to do is get the luthier to check this out when I'm eventually getting the pickups installed ....
