ULTRA-RARE 1979 MusicAid / Simmons SDS-IV Drum Synthesizer SN 4043

"This is the incredibly rare MusicAid / Simmons SDS-IV, the 1979 predecessor to the famous Simmons SDS-V. In 1978 Dave Simmons, along with MusicAid, released their first product, the SDS-III, which was a 4-channel drum synth that was inspired by the 1976 Pollard Syndrum and Japan's 1978 answer to the Syndrum, the Ult-Sound DS-4. These were the first dedicated drum synths in history. In early 1979, MusicAid / Simmons released the 2-channel version as the SDS-IV. There are only an estimated 500 of these that were made by Dave Simmons by hand!

It functions fine, but with some slight differences between channel 1 and channel 2, so you might want to go through it to make it consistent between the channels. This unit runs on UK power (230V), so if you're in a different country you will need to use a transformer."
