Korg 900 PS
Note: Auction links are affiliate links for which the site may be compensated.

Pics of the inside below.
"This is a rare gem of vintage sound, lovingly restored to bring the 1975 Korg PS-900 back to life. The power supply section has been professionally upgraded with modern components for better performance and reliability, as shown in the latest photos. Apart from this, everything else remains fully original and has been meticulously cleaned. It's in excellent shape, with just a few minor scratches—remarkable for a synth of this age.
There seems to be some confusion about the naming (sometimes called PS900), especially since the face plate says 'Synthesizer Korg Preset.' The 900PS is quite a basic but very interesting monosynth. The 900PS definitely 'borrowed' some ideas from the Pro-Soloist. Instant selection of 29 different tone colors. From the sweet sound of a violin to the chugging of a steam locomotive. Sensitive soft-touch switches and plentiful controls provide a wide variety of effects including vibrato, repeat, even the harmonics you need for a Hammond organ tone.
The PS-900 isn’t just any monosynth. It's a legendary preset synthesizer with 29 pre-programmed sounds that capture the rich, raw character of true analog. While minimal adjustments are possible, you’ll find dedicated sliders for tweaking vibrato, attack, sustain, harmony, and the Traveler Control, which governs the VCF cutoff for classic filter sweeps.
But the real magic lies in the touch bar. This unique feature, positioned at the front of the keyboard, unlocks creative potential like no other. With switches that activate portamento, vibrato, forte, repeat (note retrigger), or pitch (a semitone drop), the touch bar allows you to play with expressive, evolving textures and unexpected twists. It’s a performance feature that truly sets the PS-900 apart.
The 900PS has 29 presets: Timpani, Electric Bass, Synthe Bass, Piano, Harpsichord, Shamisen, Banjo, Mandolin, Xylophone, Tuba, Bassoon, Horn, Cello, Trombone, Saxophone, Voice, Clarinet, Accordion, Trumpet, Funky Trumpet, Synthe Trumpet, Oboe, Violin, Recorder, White Noise, Scale Noise, Harmonics I, Harmonics II, Harmonics III."

"This is an early Korg Preset 900ps; it may be a beta model as it has no serial and the formatting looks different than most 900ps. It has Korg 700 fader caps, with a few missing. It sounds great but some sliders may crackle when moving. It is a very unique sounding instrument perfect for a tinkerer or collector!"

Korg 770 - The Smut Box
video upload by Alex Ball
"A look at the Korg 770 monophonic synthesizer from 1976, an incredibly grubby sounding instrument that I've dubbed 'the smut box'. In this video we explore what it sounds like and why.
0:00 Intro
1:23 Demo1 - Ring Me
2:10 Demo 2 - Tweedle Dee
3:05 Demo 3 - Sister Transistor
4:04 Why it sounds the way it does 5:36 Demo 4 - Distant Traveler
6:34 Summary
A note: I said in the video that this synth was the last of the first generation of Korg monosynths (miniKORG 700/700S, maxiKORG 800DV, SB100, 900PS) but have since realised that the M500 came out in 1977 that does still use the 'traveler'. However, that is a very limited preset synth and I'm sure you can see what I mean by the lineage from miniKORG to the MS range.
Thank you to the owner of various instruments used."

"Superb condition with just a few minor nicks, just one slider cap missing, output is very clean. This is the very rare original WHITE livery version, I've never seen any others, I usually only come across the yellow livery version, most looking pretty battered and rarely fully working.
The only thing I need to tell you about this synth is that the power is permanently fixed on, so you have to turn it off at the mains rather than on the synth, other than that she is in beautiful physical and working condition, all knobs, sliders and other functions, including it's very unique touch bar, are all fully working as they should and the output is as clean as a whistle."

"Korg 900PS analog mono synth, it's quite a strange beast and is I believe the second model that was commercially available from Korg & released in 1975. Mono so only one note can be played at a time."

"Made in Japan, from 1975-1977, the Korg 900PS is a rare model...."big brother" to the 700S. Having twin oscillators, 37 keys (with aftertouch via the keys, or by touching the metal rail on front), 29 presets, portamento, white noise & percussive or voices, plus "harmonics" using 4 octaves (like drawbars), and the famous "traveller" (like a filter)...all this adds up to a high-performance, hands-on synthesizer.
Running @ 220/240 Vac (fixed mains cord), weight is around 13 Kgs, dims being 85 x 40 x 15 cms. Everything works, except the on/off switch does not switch off, and there are two fader caps missing. Synth has been serviced, so all faders & switches are crackle-free, and is all safe & sound inside. The wooden end-blacks were tatty, so they have been repaired, then painted in black. Generally, the 900PS is now in a "very good" condition, better than normal for a 44-y-old instrument."

"The Tremolo effect and the “repeat” switch are not working. Also, from time to time (but not very often) it goes a semi-tone out of tune for about a second.
I guess it could be fixed by replacing the right capacitors.
All the rest is working perfectly. All the switch and knobs were cleaned and lubricated.
The wooden veneers were in poor condition, so a sticky wood-like veneer was added.
This was bought for a university project only, I don’t need it anymore so it’s just taking space. These are quite expensive even with defects (like mine)."

"The 37-key Korg 900PS, released in 1975, is a rare and interesting analog monophonic synthesizer with a variety of tone colors. The tones are tweaked via the multitude of controls on the front panel of the synth, providing a great tactile experience during performance. The 29 presets on this synth really cover a lot of sounds, including shamisen (!), clarinet, violin, white noise, synth bass, and more. Further controls for harmonics, attack/sustain VCA, portamento, and more allow for even more tonal customization. Don’t miss this rare synth in very good condition!"
