That before Santana started using PRS guitars he used Gibson and these weird Yamaha guitars. We got one in at our store, it's a vintage 1985 Yamaha SBG-1000. I really liked the instrument so I did my research on it.
Full mahogany body, ebony fretboard, real mother-of-pearl inlays. The action is superb... I even took a picture. If I had the money I'd buy it myself, but at least I can work towards finding it a good home with someone.
