“Korg Lambda ES-50 String Synthesizer.

Originally bought by my father in ’79, it’s a fantastic sounding fully polyphonic string machine in lovely condition. It also has the original pristine manual and (tatty) box – it looks fabulous.

This has two layers of strings that can be detuned like traditional oscillators, it is then put through the on board ensemble effect. The sound is very rich and alive. There is also a brass and a piano section, but it really shines for strings.

It is mostly working well but there are some issues with this machine :

The percussive (piano) section isn’t working correctly, though it can be heard very faintly when playing keys.

There is also a tuning issue on each A key. It does not respond to the tuning knob like other keys but plays when the tuning is set.” Click here to visit listing on eBay

“Selling my Korg Lambda ES-50. I’ve had this for a about a year and it sounds fantastic!

Unfortunately it’s developed a couple of faults recently. The first on is that the chorus no longer engages in the ensemble section. It was working fine but then just stopped.

Secondly, each E key makes distorted noises all the way across the board. All the other notes work. Sometimes after a short while this issue will go away but always comes back when the machine is turned off and then back on. It could be a faulty top octave generator chip, but not 100% sure.

It was missing some switch covers when I bought it and I managed to acquire some replacements but I could not source a grey cover for the organ switch, so used a white one with a label over it!

This item would need someone who knows what they are doing to fix it and that isn’t me!”

” 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

“From the tech:
“Ensemble makes constant drone noise, lowest D#. When tremolo is on the signal is cut.
Pin 20 of IC on Module 7 has been disconnected. It is internally shorted to pin 19, causing tigger/decay circuit of D#1 to not function. IC on module 2 needs replacing. Part cannot be easily found besides 2nd hand (ebay, etc). AMI S10430 Divider-Keyer. D#1 trigger line still connected to module 4. Needs S10430 IC.”” Click here to visit listing on eBay
