Korg 770 monosynth for sale in superb condition. Awaiting service – will be fully-serviced before shipping. 100v unit. Great-sounding and less-common member of Korg’s late 70s 700 series with ring mod and external input.

Picture of synth for sale – more pics to follow.

If (like us) you are fan of the 700S then this 770 is definitely your sort of thing. Monophonic, quirky, has a wild ring modulator, can take an external input… Yes, it’s limited in terms of sound-shaping options, but these “limited” synths have just the kind of magic in them that we can’t get enough of. (Vintage Synth Explorer only give this three stars, but as they give the 700 just TWO I think we can safely say that they want something different to us out of their old synths…)

For sales in UK/EU the price will include VAT. VAT-free sales are possible to businesses and individuals in the EU (outside the UK) with a valid VAT Number – please get in touch if you wish to buy this way.


  • 100v Japanese model
  • For UK/ EU customers (220/240v supplies) we will supply a high quality step-down transformer free of charge with your purchase – let us know if this is not required.
  • On North American mains (115/120v supplies) this unit will run without a transformer (we run all our tests using 120v power); however, a step-down transformer is recommended for extended use – we recommend these.
  • We do not recommend using cheap generic Chinese mains transformers – please ask if you have any questions about powering this unit.
