Super cool rack mount Biamp spring reverb unit! These were used on a handful of well known recordings throughout the 80s and 90s, and sound excellent with easy to dial in controls. It features a full length Accutronics reverb tank, and a unique “drive” control - along with a powerful EQ. It has both balanced and unbalanced outs, and even sounds good as an external reverb tank in front of a non-reverb guitar amp. It works well as it should, and lived in my personal rack for a while.
It has miscellaneous signs of use as per most rack units of this vintage, to include scratches on the top and bottom from taking in and out of racks - but overall is in presentable shape, and would look great in any studio.
