Hey guys, I've been gigging an Eden WT800 in a pop/country/90's alternative cover band for almost two years now, and can't seem to get rid of the annoying harmonic "squealing" that occurs when I move my hand across the strings. I've tried other amps and it doesn't occur nearly as harshly, although sound guys say they never hear it through the house system. I'm currently running an '04 MIA Jazz through a GK NEO-410. I've tried every type of strings other than flats or tapers, and can't seem to make it go away. Any ideas?
