The SH-3A is a monophonic analog synthesizer that was manufactured by Roland from 1974 to 1981. It is unique in that it is capable of both subtractive synthesis and additive synthesis. Two LFOs and a unique sample-and-hold section provided capabilities not found in competing self-contained synthesizers of the time. The SH-3A was Roland's first non-preset based synth. It was unique for its time in that it offered mixable waveforms at different footages. The predecessor, the Roland SH-1000 could also do this but didn't offer as much control as on the SH-3A. The rhythmic pulsing in the Blondie song "Heart of Glass" is an example of its sound.

Contrary to common belief, the initial version "SH-3" did not infringe on the transistor ladder-filter patent of Robert Moog. It used a diode filter like the EMS VCS 3. The SH-3A does use a transistor ladder-filter and as a result can generate Moog-like sounds.
