Lovingly adapted for Eurorack, the SD808 brings the snare drum snap of the TR-808 to a tremendously small format. Modeled on the later revisions of the 808, this module is voiced a bit darker, with a rich sound. Beyond being a simple duplicate of the circuit, Tiptop added functionality from years of 808 implementation. Primary to this is the extended range of the Level knob, providing gain and distortion sufficient to add harmonics to the SD808 signal, a technique traditionally realized through outboard pre-amps and distortion circuits. For ease of operation, Tiptop designed a dual pulse-shaper circuit on the input, so that any trigger, gate, pulse, or clock will perform correctly with the SD808, regardless of power differences from the source.
