Oooh, I'd like to see that sometime. I'll have to find our Upright Showcase thread and bump it back up.
So, if we find any takers for #76-564... that's a pretty unusual wood combination- top and back; Peroba Rosa, on a Koa core, new pickups in 1995, apparently a modern adjustable nut too. She needs some tlc, but don't they all?
*I'm not sure what the last channel-type bridge was, but #77-637 had one, and I think #77-640 probably did too. (no pictures, but the owner was having trouble breaking strings from squared-off saddles) There can't be many more after that. Lots of changes came that year. They had come a long way since #72-001 rolled out. Think about this a minute - by the end of 1978, just a year later, they had made another 624 instruments, and then some. That's a quantum leap for a guitar-maker, especially when you consider what they were building.
