Rockman Sustainor w/dual rackmount bracket for sale. This is a Rockman Sustainor Model 100, with an early production serial number, #00721. All switches and sliders have been cleaned with Deoxit D5 and F5 respectively. This unit is from the original owner who had a small private studio. The unit is in good working condition. The only issue is that the preamp gain slider tab had a piece chip off at the surface of the faceplate. It is still useable/accessible with a fingernail. Physically, there are some scuffs on top and bottom of the unit. Also included in the sale is the rackmount for two Rockman units. It includes the screws to mount two devices to the rackmount. See pictures.
