Korg 770

“The 770 is a very early, very cool Korg synth, but you probably know that or you wouldn’t be looking.
White noise, tuned noise, 2 different ring modulator modes, 2 oscillators, High and Low Pass filters.

The great thing about these is they sound like nothing else. If you’re an analog synth guy who already has the normal stuff, this definitely opens up another range of sounds you can create. In fact you can go inside the unit and tweak trim pots to alter the behavior of the filters! You can also run external audio through them. It has a mean, raw sound that later pieces like MS20 can only dream of!

The only issue with this is the auto bending feature doesn’t work consistently, but it isn’t broken. The portamento is more musical and works fine. Apparently it was used near some spray paint as there is some on the right end cheek and a very subtle amount on the far right side of the control panel, but unless you’re staring at it under bright light you won’t even notice.” Click here to visit listing on eBay

Korg 770

“Selling my very special and rare Korg 770. This synth is in incredible condition for 42 years old. Cosmetically it has some signs of wear and a hand full of the original knobs have been replaced as you can see in the photos. Everything works. Not only does everything work, I have also retrofitted the synth with a Kenton CV kit so there is cv control over Hz/V, gate, and filter. Sequencing this machines notes and filter is INSANE. You can integrate this with an analog sequencer or kenton midi to cv box (or any other cv source even a korg sq-1). Last year I also had Rosen Sound in Los Angeles install a midiplant so not only can you control the synth via cv, you can also trigger notes via the midi port on the back with a quick flip of a rear toggle switch. I personally still prefer the control and resolution of straight cv. The synth is really incredible and I’ve sampled more sounds from it than any other instrument I own. Have a listen to some demos on youtube if you aren’t familiar. This machine is from another planet. The serial number is 770073 and it was one of the first units produced. Extremely rare and hard to come by for good reason. Also including a custom made dust cover.

Unit is being sold as is due to its age. It has been very well taken care of and had a complete service just over a year ago. While it was in the shop they cleaned up all solder connections and any oxidized connections.”

“Sie bieten auf einen funktionierenden analogen Vintage – Synthesizer KORG 770 mit kleineren optischen und technischen Mängeln.
Dieser monophone Synthesizer bietet trotz seiner geringen Größe spannende und teils einzigartige Möglichkeiten zur Klanggestaltung
mittels z.B. Ringmodulator und Audioeingang. Das Teil klingt gut und nicht nach “Massenware” – ein Liebhaberstück!
Wegen Neustrukturierung muß ich es abgeben. Es wurde zuletzt in Nichtraucher – Studioumgebung eingesetzt.”

Korg 770

“Wonderful Korg 770 mono analog synth with two ring modulators. The VSE description does not do justice to the possibilities of this synth. Recently serviced and recapped. Fully functional with cosmetic issues: the silver caps of the knobs were removed by the previous owner and the portamento knob is not the original but a generic replacement that fits corectly (these knobs are the same used by the original MS20) There are four chips in the wooden panels (all pictured) and three very small scratches on the top panel (all pictured along a dime for reference). 3-day return policy. ” Click here to search for synths on eBay
