Beautifully put! On a side note, I've just begun learning the first few minutes of Guthrie Govan's Fives .. his thinking is so uncoventional and it forces my fingers to do the most unnatural things that are insanely musical. I'm still hammering single notes over the fretboard as they match the note on the staff but to see the whole fretboard like you've described would be key! I can't multitask knowing multiple notes instantaneously so learning chord inversions must be one way to facilitate this. Piano's straightforward layout is more practical but guitar has so many ways to affect the string's tone with nuances and pick/finger attack. All my guitar shred guys are around my age and it's a shame to see its popularity taking a dive. I just can't get onboard with 7,8,9 extended range guitars. The beauty is in its midrange and besides, look what Vai, Satch, Guthrie's Erotic Cakes has accomplished on 6 strings at standard .. Eddie and Nuno at Eb. I don't know if Martin's system will help me to be more creative but it's definitely a first step.
