Rare SWTPC Psych Tone 1971 digital analog synthesizer sequencer triadex Muse electronic music Published on Apr 28, 2013 salvadory
Interesting note that this was the first digital sequencer synth prior to the Triadex Muse, the first digital synth.
"First of all my camera is terrible so my apoligies for audio and video-( my camera keeps shutting off even though the power is charged-)
However this is a very rare SWTPC psych tone music composer from 1971 with original magazine article- the only video on youtube as of now - my model is in very good full functioning condition and is a much sought after piece- a precursor to the famous and also rare Triadex Muse-
An interesting missing link in synthesizer development from the early age.... quirky interesting patterns and sound- design way ahead of its time in my opinion- plenty of switches and knobs to make things interesting!"
Note the Popular Electronics article at the end.

Looks like a crusty, beat-up KORG Volca in a custom case with speaker. These do come up now and then. You can find some in the archives here. You can find pics of the inside/backside below.
Note the video above is not for this specific listing. You can see it is dated 2013. I found it searching for demos on YouTube. This is the first demo of the SWTPC Psych-tone posted on the site for that matter.

Essentially a non programmable preset synth. The actual name of it is the Pony Synth as you can see. Via the listing:
"retro vintage eko pony synth keybroad synthesiser
got this new over 30 years ago from bill greenhalgh of exeter devon
full working order. lots of fun and now has become very retro etc"
Anyone know who bill greenhalgh of exeter devon is? I ran a quick search and didn't find anything.
Update via Matthew North in the comments: "Hi there I worked at Bill Greenhalgh from 1992-1994. It was one of the biggest music shops outside of London over 3 floors sold absolutely everything."
