via this Reverb listing

"Very good condition, serviced by Rosen Sound, and includes a light-duty Tuff Case for easy transport!

Cosmetic notes: small chip in wood veneer edge under keybed, and the mod wheel shows a bit of wear. Both of these issues are shown in the images.

Released in 1981, the Korg Mono/Poly is known for its four VCOs, flexible modulation options, and unique mono/polyphonic switching, making it a versatile beast for both fat unison leads and unique, syncopated arpeggios. Its cross-modulation, oscillator sync, and deep routing options open the door to wild textures and sound design experimentation.

Specs & Highlights:

4 analog VCOs with independent tuning
Mono, Poly, and Unison modes
Crossmod, oscillator sync, and flexible LFO routing
Built-in arpeggiator and chord memory
Classic Korg 24dB/octave low-pass filter
Full MIDI retrofit kits available (not included, but easily added)
Used by artists like MGMT, Chromeo, and Jimmy Edgar, the Mono/Poly is a staple of vintage synth setups and prized for its unique voice architecture and beefy tone.

This unit was serviced by Rosen Sound, a trusted name in analog synth repair, so it’s running great and ready for action. Includes a Tuff Case (light-duty) to keep it safe during travel or storage.

30% of proceeds will benefit the Bob Moog Foundation, helping inspire future synth pioneers and preserve electronic music history."

Inside Tom Oberheim’s Garage Workshop

video upload by Anthony Marinelli Music

See the full interview here, and the SEM Story here.

"Step inside the legendary garage workshop of Tom Oberheim—the birthplace of some of the most iconic sounds in music history. In this rare behind-the-scenes tour, Tom shares his latest creation: a custom-built computer he’s designing entirely from scratch—just because he loves the way it sounds.

Along the way, Tom opens up his treasure chest of innovations, showing us priceless prototypes from his storied career, including the original Maestro Phase Shifter prototype and circuit boards that paved the way for his groundbreaking synthesizers.

I’m joined by Rob Rosen (Rosen Sound) and Marcus Ryle (Alesis, Line 6) as we hear directly from Tom himself, walking through this sacred space filled with history, innovation, and pure sonic imagination.
👉 Don’t miss this intimate glimpse into the genius of a true pioneer."

This Little Box Changed Synths Forever | Tom Oberheim’s SEM Story

video upload by Anthony Marinelli Music

See the full interview here.

"How did the legendary Oberheim SEM (Synthesizer Expander Module) come to life? In this video, Tom Oberheim himself tells the story of how necessity became the mother of invention.
After creating the world’s first digital sequencer, Tom needed a dedicated synthesizer voice to play back the note information generated by the sequencer. His solution was the SEM — a compact, self-contained synth voice that could be sequenced while leaving a musician’s main synthesizer free to perform alongside it. This groundbreaking idea gave players entirely new creative possibilities and laid the foundation for some of the most influential instruments in music history. Join me, along with Rob Rosen (Rosen Sound) and Marcus Ryle (Alesis, Line 6), as we hear directly from Tom about the innovation that started it all.
👉 Discover how the SEM was born and why it changed the future of synthesis."

The Secret to the "Oberheim Sound"

video upload by Anthony Marinelli Music

See the full interview here.

"Discover the true origin of the “Oberheim Sound” in this rare and revealing conversation. Legendary synth pioneer Tom Oberheim himself explains how he dialed in his iconic tone—locking himself in a room with nothing but a bag of resistors, capacitors, and an oscilloscope. Over several days, Tom tweaked and tuned until he was satisfied, even embracing a level of filter distortion that most engineers at the time would have rejected. That bold choice became the unmistakable warmth, grit, and musicality that defined the Oberheim legacy.

He’s joined by Marcus Ryle (Alesis, Line 6) and Rob Rosen (Rosen Sound) as they dive into the legacy of Oberheim instruments—from the SEM to the OB-series—and how they shaped music for artists like Prince, Stevie Wonder, Queen, and Daft Punk.

This is the inside story of how imperfection became perfection, and how one man’s vision changed music forever. Don’t miss this exclusive conversation with three icons of synthesis history."

Tom Oberheim: The Genius Behind the Greatest Sounding Synthesizers

video upload by Anthony Marinelli Music

"Today, we’re at the home of Tom Oberheim — one of the original pioneers who shaped synthesizers and music history. Tom's legacy includes some of the most groundbreaking innovations: (a stand alone ring modulator, the first commercially available phase shifter pedal (my personal favorite), an early digital sequencer, the Oberheim DS-2, and the SEM the first commercially available polyphonic synthesizer made in 2, 4 and 8 voice models, followed by favorites such as the OB-X, OB-Xa, OB-8, Xpander, Matrix 12, DMX drum machine and more... of course, most importantly he gave us the unmistakable "Oberheim sound" on his entire collection of iconic synthesizers that have inspired compositions and performances on countless records by multiple generations of artists.

Joining me for this special interview is my friend Rob Rosen from Rosen Sound—talented musician and renowned expert in synth restoration and preservation, and someone who's worked closely for a while with Tom to keep Oberheim instruments and ALL vintage synthesizers alive for future generations of musicians.
We’ll also be joined by Marcus Ryle, who's done so much. Marcus began his career working closely with Tom, at Oberheim, was a session musician, designed dozens of affordable and accessible products for Alesis - including the ADAT multitrack recording, Quadraverb digital reverb, and HR-1 drum machine, and later co-founded Line 6 (creating innovative guitar effects and revolutionizing digital modeling technology). His insight into Tom’s innovations—and his own contributions in music history —makes this a rare, deeply meaningful conversation.
Let’s get into it."

Moog Memorymoog w/MIDI kit

Note: links to listings are affiliate links for which the site may be compensated.

via this listing

"This Memorymoog has been loved, and it’s got the vibe to prove it—some scratches and a worn look, but it’s fully functional and ready for more. If you’ve ever played one, you know these synths are beasts, and the sound is just massive. I’ve used this on so many records, it’s time to switch things up, but if you’re after that iconic Moog tone, this thing delivers.

It’s got the MIDI kit installed, making it a breeze to hook into modern setups. The original fan? Crazy noisy, so I replaced it with a quieter modern one—now you get all the analog magic without the extra hum. It’s been serviced every six months for regular check-ups, and back in 2018, it underwent a full restoration by Rosen Sound in LA, so it’s been well taken care of.

And yeah, all six oscillators are tuned—no small feat with these machines. If you know Memorymoogs, you know the oscillators are notorious for drifting out of tune, but I’ve kept them locked in and serviced. Be very careful when getting one of these and who you are buying it from. Constant service check ups and love is key for these"

Oberheim TVS-1 Two Voice Synthesizer SN 0456

Note: links to listings are affiliate links for which the site may be compensated.

via this listing

"This is a professionally fully restored Oberheim Two Voice. It's in physically excellent condition for its age. The original tolex is in amazing shape with only a couple little tears in the lid. The keys are perfectly pristine white, no fading at all. You can tell this spend the majority of its life with the lid on judging by how nice the key whites are. Every module was professionally restored by Synth Tailor a little over a year ago, the Sequencer was restored by Rosen Sound and Synth Tailor. Restoration documentation will be provided to the new owner. Definitely not the cheapest TVS you can find but if you buy one that is not restored you are looking at 2-4k in labor to get it back to a reliable state and a very long wait time for it to be completed."
