I seem to have an issue where roughly all the notes on the low E string between frets 5-9 are louder than other bass notes, regardless of the preset i'm using....it's as if the "resonance" knob on my 5150 amp is cranked all the way up, but only for those notes and in every factory preset....anyone have an issue w/ that? is it perhaps a global EQ setting that i need to modify? Thanks!
