I had the pleasure of hearing Dave last week at legendary cleveland joint, NightTown. He sounded amazing. I picked up his latest CD Strykin' Ahead which is fantastic. This is one you don't want to miss.
This is an exercise from Sheets of Sound for Guitar Volume 1. It's 5.11.1 and it's a diatonic 5th and 4th arpeggio. Very difficult to play. I decided to relearn it and i'll be adding video to this in a few days when I get it a little better under my fingers!
