” For sale is one of the all time greats of synth sound and history…
Vintage Oberheim SEM module! 100% working. Face is in great shape!!!! All knobs, functions work great. The housing shows wear (bottom and sides). The output for low was modified to 1/4 inch. The unit appears to have been recapped properly- the original tropical fish caps are still there (never swap them unless you MUST… you will hear a difference) There has definitely been some work done inside- the 1/4 mod, recap, some wiring looks non original. BUT I always took it as it was serviced. The unit sounds and performs as it should but it has NOT been calibrated. Assume drift.
It tunes awesome and HOLDS tune, unlike my Minimoog LOL… which btw it was MADE for. As an expander for a mini, its ridiculous. And theres a mod you can do on your mini for CV out and you can control it from the mini!!! (It was called the “S”ynthesizer “E”xpansion “M”odule LOL) Thats how I’ve been using it and it kills. But I’m so tired of multi tracking chords note by note LOL!!!!
This is an actual SEM not a rehoused module from a 2, 4 or 8 voice.”

“This is a Memorymoog Plus that I bought directly from Moog when I worked there as Marketing Manager. I had Don Besecker of DBM Tech install a better MIDI implementation system, while keeping the original Moog hardware. I had Wes Taggart of Analogics do a complete restoration about 10 operating hours ago. All factory patches and sequences are in memory. Everything on the instrument operates at, frankly, better than original factory quality. I include the owner and service manuals and the oh-so-rare cassette interface cables. There are some scratches at the top of the front panel, as you can see in the photos, but I doubt you’ll find a better-sounding Memorymoog anywhere.”
