This Gibson/Dobro reaonator is 1 of 20 or less prototypes of the DM-33C resonator guitar. The prototypes feature an abalone covered headstock and a gunmetal gray finish. This one belonged to a Gibson artist relations representative before it was sold to a collector in 2007. A little bit of tarnishing around the bridge where palm would touch. Includes OHSC. Reach out or miss out!
