Fantastic! Spread the gospel of the EADG!
I took "lessons" from Juano of Sky Cries Mary. I was already an accomplished bass player at the time, and my "lessons" were just us jamming together for an hour or two, and riffing off each other and the loop/drum tracks he had programmed.
It really stretched my skills, and got me playing outside of my rut. Rejuvenated my playing.
So sometimes, it's not about teaching a player new skills... sometimes it is being a sounding board that throws new ideas into the mix, too.
