"One of very many items from Calum Hunter's superb home studio. Beautiful Cwejman S1 Mk2 semi-modular analogue synthesizer. Rare and sought-after, of course. This gorgeous near-mint cream / eggshell coloured version is serial number 291.

Thorough checking shows that the PWM range of one oscillator is much lower than the other, but otherwise everything seems exactly as it should be. Packing 12GBP to include a UK or Euro IEC mains lead."

"MINT CONDITION (see images), AS IF YOU RECEIVED IT FROM THE SHOP IN 2019!

This is the legendary Cwejman S1 MK II synthesizer, unused in box. I received this in 2019 after ordering ist sometime mid 2010s ... and due to different life circumstances never used it as when I received it I just had moved and no space for my Eurorack system.

As a result, this unique synthesizer is like a time capsule, it was safely stored in my office in its original packaging in a cupboard and is in mint condition (refer to images)."

"One of the classic analogue modular (OK semi-modular) synths. It's actually not perfect condition on cosmetics, as you can see in the photos. There are some scratches on the sides and back - though the important bit (the front panel) is in very good condition indeed. But the sound is excellent as expected, beefy and powerful, and really such a good semi-modular with complete Eurorack and MIDI compatibility. Switchable voltage - supply your own IEC lead for price, ease and safety of shipping."

video upload by You Kill Years

"Here is a fairly structured (for me!) song, featuring primarily the S1 (sequenced by the serge); a Random * Source Crocodile panel (sequenced by the pyramid); some percussive elements (just a Serge VQVCF, pinged); and some noise & shimmer from the Cocoquantus & ADDAD112)."

"One functional quirk is that the second adsr gets quite long at different knob settings than the first one does. Just a thing to be aware of as you dial them in.

If you are reading this, you are probably aware, but I'll say anyway: as it's a fully-analog instrument, the oscillators do not track as well as DVCO-based synths I've had. I calibrated it once when I first received it, and I've been satisfied from then for my needs. Note though that I've never had any drift problems with them—once the machine has warmed up, you are rock solid.

I have used this instrument quite a bit, and I will miss it a lot. I included a link to one of my videos with it" [above]
