Here an example of a rare 45+ year old Yamaha SG-45, a single cutaway Yamaha SG; these guitars were produced during a short period from 1973-73;  The finish was simple and the 2 available finishes were natural wood, mahogany or alder coloured. The sound of these vintage gems is outstanding, very full and with a strong presence, ideal for rock and rhythm. The models in the line up were the Yamaha SG-45, 65 and 85.
