Interesting stuff... yes... Jeff IS the best and the most inventive, though I think he's made not progress for a few years now. (Unlike me... I'm going backwards at an alarming rate - thanks to Arthur)
I'd love you to post the backing track for other members to have a go at, and... share with us the position and technique for using those lower fret harmonics which have such a gut wrenching, emotional impact...
Well done!
