Why would a guitar sound in tune clean, but slightly out of tune distorted? My son's BC Rich Warlock with distortion on can sound great when playing an open D chord, an open G chord and pretty much any bar chord up the neck. But when we play an open E chord distorted it sounds out. Played clean, it sounds in tune. Maybe distortion enhances the notes enough so we hear things different. When the D & G chords are in tune, the only way to make the E chord sound good is to muffle the 3rd string/1st fret instead of playing it with the E chord. I know it's probably the intonation, or the nut, or the truss rod. I have had it to a technician twice, but he has never heard it distorted. I will be taking it back a 3rd time (no cost) and have him tune it and play it distorted to get his reason or maybe his fix after he realizes something he may have missed. Any additional input would be greatly appreciated.
