Rick may have started on it, but I think Gruhn's guys finalized the restoration on it. Looking at the pictures from a couple years ago, I wonder if they didn't undo some of what Rick did in the way of putting wood back in the top and neck beam. He was talking about a piezo, John East filters, (and yes a quad) rigged for stereo output, but never got around to it. I don't know if Gruhn got impatient with Turner or if there was some other disagreement... no earthly idea, but I can well imagine, knowing both of those guys various... ummm... eccentricities. Whoever did the actual work on "Mission Control", they did a very nice job. That bass was a heartbreaking mess that it didn't deserve to be, and now it's a playable instrument again. I'm with Greg [glocke]... I'm thinking about making a pilgrimmage to Nashville and play it!
