So recently I have gone through a massive (and very expensive) overhaul in gear. After upgrading to some pro series equipment I went and got some nice planet waves cables to make sure I got the best tone running through everything. I can turn my crank my head to the max through my 410's with the bright button in and tweeters on (God help us all) and with the blending knob set central between neck and bridge I get whisper quiet performance which I am very happy about. One thing remains. Occasionally if I solo the neck or bridge pickup, which are a tad noisier on their own, I get that buzz that differs in volume depending on which way you are facing when you stand near the amp. Is avoidable in any way or what even is this called? Not that it's really an issue, even at it's loudest it's fairly quiet. But still, something I wish to learn about.
