Original Simmons SDSV Brainbox circa early 80's in perfect working condition. Recently tested in studio, all channels, dials and buttons working perfectly, all sound clean, perfectly responsive and clear as a bell. Hasn't been used since the 90's, has been stored sealed in a dust-free box in a house, and as such is perfectly preserved. Original warranty seals are still intact and unbroken, as seen in photos. Comes with UK power supply cord. Cosmetic scratches to its surfaces as seen in the photos and one control knob on one of the Tom channels is missing its cap. Otherwise, it's good as new. Rare opportunity to own a legendary piece of gear of its era.
