I have not seen much about the DR1-ST. I just bought one for under $100. It sounds fantastic! Great sustain and low action. It was converted to a lefty prior to my purchasing it so I jumped on it since I'm a lefty and decent used lefty guitars are hard to find. Pickguard was removed and not replaced. This one has the paper label with serial number 707026 and says Made in Korea. Any clue to how old this might be? And any other info would be great too. Thanks.
