The SP2016 is a 3U rackmount box with vertical faders to adjust the parameters, chunky '80s buttons, and a small LED alphanumeric display — was fairly crude by modern standards, but three of its algorithms have stood the test of time: Stereo Room (with source-related stereo early reflections), Room Reverb (with a mono input) and High Density Plate. These reverb programs all sounded far more natural than any other reverb technology could manage at the time (plates, springs, tape echoes, and tiled rooms) and they always seemed to sit well in mixes. All their parameters were instantly adjustable, which was revolutionary. The SP2016 reverb sounded quite distinctive, but they were also very believable thanks to the way the unit generated a surprisingly complex early-reflection pattern, complete with a realistic build up of reverb density over time, combined with a smooth and natural decay tail.
