Some friends of mine recently bought an old (1934 or thereabouts) Dobro, and while putting a new set of strings on it, they discovered it was set up for seven strings. They called the Gibson factory, and the factory historian said he'd never heard of such a thing.

I promised my friends I'd ask the gurus at Mudcat. Does anyone have any information I can pass along? For instance, one of the things they'd like to know is "How the heck do you tune it?"
