The Roland SH-3A Synthesizer is an analog monophonic synthesizer released by Roland in 1975. It was used by a variety of artists, including Kraftwerk, Tangerine Dream, and Gary Numan.

The SH-3A is a subtractive synthesizer, meaning it creates sound by filtering out certain frequencies from a basic waveform. It has two oscillators, a low-pass filter, an envelope generator, and a noise generator. It also has a built-in spring reverb and a ring modulator. The SH-3A is capable of producing a wide range of sounds, from bass and lead lines to drones and sound effects. It is also capable of producing a wide range of modulation effects, such as vibrato, tremolo, and portamento.
