” This is a CLASSIC 1979 ANALOG synthesizer. Probably the warmest string machine i’ve ever used. Very sad to be selling it but times are tough and money is tight.
You can find these on Reverb and similar places occasionally, but I can guarantee they are going to need to be serviced. Solder from 1979 just doesn’t keep a connection in 2022. It’s just physics. Sometimes chips go bad. This one has perfect key action, and no issues with any components. Everything is cleaned and resoldered and checked by a professional.
If you’re into vintage analog synths and string machines.. this is your best best. You may get lost in the warmth and depth of the chorus on this rig. ” Click here to visit listing on eBay
“Vintage
“All functions are working. The unit has some signs of age but overall in great condition!! All keys, sliders, knobs and buttons working well. Tested before listing. Please see pictures” 
“This listing is for one Korg Lambda vintage synthesizer. It is working great and other than some scratches here and there, looks good too. There are not many Lambdas out there, an unfortunate fact as they are well-equipped at performing 70s/80s polysynth sounds, Solina-like stringsynth pads and 70’s-esqe synth-clavs, pianos, etc. The sound is very similar to the PS-3100/3200/3300 range of synths. Good luck and happy bidding!”
