Jack,
Good or bad, they are a part of our steel guitar history, and as such I feel some should be preserved. They weren't the best guitars, and the crossover feature certainly gave a lot of players grief. They were built during an era of experimentation, and learning at Sho-Bud, but as a result, most subsequent Sho-Bud models were better constructed.
I hesitate to post these, but here is a 1969 Crossover that I restored. I think it looks fairly decent, sounds absolutely wonderful and stays in tune.
I found John Coop to be a wealth of help and information, and just an all-round good guy. Not to mention he's "THE" source for some of these old Bud parts!
If any of you guys are ever in need of the type services John offers, I highly recommend him.
Cheers!
Benton
