I've owned my axe for a while but i'm still having some problems dialing in amps to sound good at bedroom volumes. I'm getting muddy sound power chords when they are lower sounding, but then as I move up to solos around the 12th fret it sounds ice picky. Recommendations? This happens on a lot of various amps. I've tried changing cabs which sometimes help. I've tried cutting the lows which also helps. Any other recommendations?
