Guys, I'm confused... To start with, the bass being used: 2012 USA Fender Jazz Bass w/ CS60s pups I understand that 60 cycle hum is different than the high pitched one that you can stop by placing your hand on your strings. But my ears seem to think they're related When I play somewhere with really bad grounding hum (the high frequency one that you can stop by touching metal), my 60 cycle hum seems to also get much much louder. And contrarily, last night I played somewhere and had no extra noise whatsoever when I wasn't touching my strings. And similarly, I swear I couldn't even hear a 60 cycle hum at all. We were turned up quite loud too. I was playing through a GK 2001RB (not my amp) Why do my ears think that they're related to one another? I was on this mad hunt for hunt for hum canceling pups that sound just like single coils... As many of you know, this is a tough task because there's no such thing. So, I'm wondering, should I just get the damn bass shielded first and see what that does?
