Yeah, I think Oscar Schmidt is the only one. I played one of these when Tom Ferrone, from Oscar Schmidt, actually had one sent to a local store for me to try out. I was thinking it was something I would be interested in having. I was wrong, and felt guilty when I didn't buy it after Tom had been so generous and helpful. That neck is WIDE, much wider than I had anticipated. Most difficult to play, (for me). I think the string spacing is wider than most guitars.
Don't get me wrong. It was a terrific instrument. It was set up well, intonation was good, sounded great, and was absolutely beautiful to look at. If the neck width was what I wanted, I would have bought it in a heartbeat. (ridiculously inexpensive, too) I am always amazed at Oscar's instruments and their value.
