“Korg Lambda in good vintage condition but with a few issues. First off, this contains two banks of voices: percussive (piano type sounds) and ensemble (strings, organ, brass, and chorus). This synth is famous for its string sounds and the fact that it has THREE analog VCOs which can be detuned for thick, complex string sounds. I bought it to use as a substitue for Polymoog Vox Humana type sound, which it definitely can deliver. The piano/percussive sounds aren’t bad, but they aren’t really what makes this synth useful. All voices work and function knobs work, except the percussive section tremolo doesnt work (one switch and one knob) and the chorus push button for the percussive section is missing and not working. For my purposes, these flaws didnt matter at all, because everything about the string section on this synth works including the attack/sustain, LFO, and chorus effect. It’s also easy enough to use an outboard chorus effect with the percussive piano sounds, so that’s not a major problem either. There are a few outputs on the back, but the only one working is the MIX output which again, was fine for my purposes. Cosmetically the control panel is in great condition except for the one missing switch. The wood finish is worn and one of the end pieces should be tightened. I haven’t opened it up to tighten the screws but this should be pretty straight forward. For the right Buyer who wants this for the perfectly working ensemble/string sounds and effects this will be a great bargain…the tremolo circuit, chorus pushbutton switch, and cleaning up the output jacks (resoldering?) might all be easy fixes, but I have too many instruments to play so I haven’t had these looked at. This synth is a bit wide because the top was designed to support another mini-synth on top. It’s heavy, but for shipping this I’m actually more concerned about the size than the weight. Local pick-up is prefered because I dont have an economical way to ship anything and even the box will be expensive for this. If someone in the NY or NJ area buys it, it would be great to make arrangements for local pick-up and avoid the shipping charges. Returns will be accepted if the item differs from this description, so it’s NOT sold as-is, it’s guaranteed to work as described. ” Link
“Vintage Korg polyphonic synthesizer keyboard
Its wood grain and the only thing wrong is one of the keys is broken but not missing – it’s taped on. Otherwise works and is in great shape.” Link
“Excellent pre-owned condition. Very clean with all keys functioning and all buttons, knobs and switches intact” Link
“This Lambda is in great functional condition. All 48 keys work perfectly, with no sticking, double-triggering, cracks, chips, or any other issues. All preset voices and all three VCOs work and sound as they should. The joystick, unlike most Lambdas, is undamaged and still has the knob-top-thing. The only issues that I can find, none of which significantly affect the playing or sound, are the following. The volume sliders for the two sections sometimes make a small amount of noise while being moved (but not after they are set) – I think this is because I haven’t used it in a long time, and during the time when I was checking everything out, just exercising the sliders got it to where there was nearly no noise; so little that most sellers probably wouldn’t mention it, but I want to give an accurate description of the condition. The two push buttons for enabling the BBD chorus for the two groups of presets occasionally need a second push to engage the chorus; however, once engaged, they stay set. I usually left the chorus on all the time, so this was never an issue for me, and they usually do toggle correctly on the first click. Those are the only operational issues to be aware of. ” Link
“Perfect working order and amazing cosmetic condition!” Link
The synth is in excellent working condition. I have used it extensively for long periods of time without any issues. Audio signal is strong with good signal/noise ratio – perfectly good for recording. All knobs and sliders work smoothly without crackling. All features are fully functional.
The cosmetic condition is quite good thanks to the replaced woodwork but you can find some scratches under the keys and some slightly worn out legends around the joystick (see photos).” Link
“Great shape, comes with a hardcase.” Link
“Fully tested and guaranteed. All functionsand keys are working properly, and this sweet vintage synth sounds amazing. There are a few scratches, and a slight bubble in the panel on the right side, but overall the unit is very clean. The auction includes a heavy duty Calzone keyboard flight case as well as the original Korg cover.” Link
“Here is a nice description of this Korg ES-50 i have (with some edits). I must admit i copied it from another auction but it explains it better than i can:
Vintage and in great shape, Korg ES-50 (aka Lambda) analog synthesizer. keyboard plays without issues. Every key works, every sound works. pre-midi, 100% anolog synth. The analog strings alone are worth the price of admission. ” Link
” Vintage and in great shape, Korg ES-50 (aka Lambda) analog synthesizer. Of course, a 33 year old vintage synth will show its age, but the wood is in good shape and the keyboard plays without issues. Every key works, every sound works. If you are looking for a pre-midi, 100% analog beastie, this is your synth. The analog strings alone are worth the price of admission.
The Lambda ES50 is a vintage poly-ensemble type synthesizer with slightly editable Preset orchestral sounds. It is divided into two sections: The Percussion set includes Preset pianos, clavis and harmonics; The Ensemble section has Presets for brass, strings, organ and choruses. Filter and envelope controls affect the different instruments individually. The Lambda has 96 discrete envelopes and VCAs – two for each key – a very unusual design. There are also vibrato and chorus effects.
The Percussion group and Ensemble group each have their own separate outputs which is nice. A joystick is provided left of the keyboard for simultaneous control of pitch bends and chorus phase speed.
The String sounds are the nicest sounds this synth can create. With three oscillators you can vary and detune them enough to get a nice layered analog string. Piano and Brass sounds are pretty cheesy. The Lambda is cased in a great big wooden case that gives it that authentically vintage status. ” Link

“Classic analog tone, top notch string sounds, 3 VCOs, full 48 note polyphony (48 keys), 9 memory patches, gate trigger out, pitch bending and phasing via the joystick control, built in 1979, one of the last analog synths of the era, highly regarded among enthusiasts, very lush sounds similar to the rare Korg PS3100 are possible. Has all the typical piano, clav, harpsichord, and organ sounds, which can be layered and tweaked a bit to good effect.
This one is in good working order, we plugged it in and tested everything and it all seems to be good, fun to play. The wood housing has quite a few marks from years of transport and storage, scratched on the top, dings along the edges including worn corners, the four rubber feet are missing from the bottom, a little dusty but not bad. No road case but it will be packed with sufficient foam and heavy cardboard for shipping. ” Auction ended. Click here to browse on eBay.
“Here we have Korg’s glorious classic 70′s analogue string synth as used by Rick Wakeman and Keith Emerson. It oozes vintage sounds that newer synths just can’t replicate properly. Described and accepted by many to be one of the finest it has some built in phasing FX that enhance this fully polyphonic keyboard. Please note that this model pre-dates MIDI so it can’t be connected to your rig unless you install a retrofit if one exists.
Sadly, it’s not working correctly but the good news is that it’s completely intact with no missing knobs or sliders and the joystick stalk is unbroken. Cosmetically it has some wear n tear also a tiny hairline crack to one key but considering its age that’s to be expected. When switched on it will sound for a fraction of a second then just a low swirling noise. I’m sure it can be easily repaired and there are companies who specialise in this field, or perhaps you have the neccessary skills which I don’t. ” Auction ended. Click here to browse on eBay.
