Ry had a curiously similar rig around the late 80s/90s. He had a Supro (one of the bigger ones) or Gibson (GA-20 maybe) amp with a preamp tap that went to a HiWatt power amp and some JBLs (definitely a 2x12, often with a 1x15 d130). Pedals, guitars, musical adventures were of course different philosophies, but Ry is a folk musician, and I always think of Jerry as one too. I think it wouldve been awesome and perfect if JGB had covered "Little Sister" or "The Very Thing That Makes Her Rich (Makes Me Poor)". I've never heard of any collaboration or conversation between the two, I think they would have been kindred spirits. I have heard comments from Ry though that he was never too interested in the psychadelic scene, and I think is a pretty straight laced old folkie.
