I dont know why but when im playing on the 15th fret and lower i can play fine, my sweeps, alternate picking runs all sound good and clean. Yet when i play higher up it never sounds good. If i play a typical E minor arpeggio (starting at 19th fret, A string) it never sounds as clean as a couple of frets lower will. When i play standing up its worse too. When I play the intro the hands without shadows, the lower part is fine, but higher up I struggle, especially with the octave higher E minor arpeggios (24-19th fret high E string) like in No boundaries. Any suggestions?
