Cwejman S1 MK II

“Up for sale is my cherished Cwejman S1 MKII from the final batch of production in 2019.

Has seen minimal use the past couple of years due to work commitments, and been kept covered and stored in my temperature regulated, pet-free studio in Central London.

I sent it for a service/healthcheck over the summer so the buyer has additional peace of mind.

The synth sounds absolutely great and plays like new.

There are a few rash marks on the cheek ends (see pics), but the unit itself is in great condition overall (see pics).

The box is nothing special and a little beaten up but item will be double boxed and sent shipped, insured.” Click here to visit listing on eBay

Cwejman S1 MKII

“Hello friends, 

Consolidating my big toys as I make space for my kids.
Tough decision because impossible to replace – these units are getting rarer and rarer to find, especially last batch in this condition.  

The S1 is the pinnacle of Cwejman engineering and considered by many to be the best semi-modular synth ever made.
There are no plans for a re-issue.  

This unit is a 2019 one from the last batch of 150 made.

This is easily identifiable by the way the serial number is written on the back.  
I’ve noticed some sellers don’t post rear pics of their units. This is because they are not last batch.  

Also, the synth was serviced at Cwejman’s official service centre in early 2022 for peace of mind.

Cosmentically and functionally beautiful. Some rack rash around the ears and a small hairline on the top rear corner as seen in the pics.
Sounds massive…”

Cwejman MMF-1S Multi Mode Filter

“Mint condition, owned from new, around 3/4 years old.
Probably the best filter ever designed by Cwejman, saturation sounds incredible! This one is hurting to sell. I’ve owned most top-end eurorack filters, like Macbeth, ACL, Shippmann etc and this is by far the best multimode filter available in Eurorack. Condition is impeccable, I look after my modules very well. This is super-rare and the circuit isn’t replicated in any of the Cwejman semi-modular synths like the SM-1 etc.
Original box.” Click here to visit listing on eBay

Cwejman MX-4S 4 Channel VC Stereo Mixer

“Incredible mixer in excellent condition. As signal quality goes, it’s one of the best mixers in the eurorack format. I love this mixer! (I have 4), but I plan to reduce the number of cases and can live without the extra mixer. Includes the module and ribbon cable only. Note, there is a very light hairline surface mark near the upper right corner (visible in photograph). Does not include the box. Will be packed well for protection and shipped quickly.” Click here to search for synths on eBay

Cwejman SM-1 Synthesizer Module

” Very sadly selling this truly one-of-a-kind incredible synthesiser. Unfortunately I have hit hard times and so this has to go. I hope very much it will find a good home.

This one is signed by hand by Wowa Cwejman and carries a very nice serial number – 007

It is 100% perfect in condition and function. The total combined cost of putting this together by using individual Cwejman modules would be well into the £4-5k range, if you are even able to find them. It’s incredibly rare to have so much Cwejman synthesis in one module. ”

Cwejman FSH-1 Frequency Shifter

” This listing is for a Cwejman FSH-1 frequency shifter synthesizer module with the original packaging and ribbon cable. This module is essentially new it was used briefly for experimentation and then placed back in its packaging and stored safely on a shelf in a back room. Note that I will be shipping this in a box much larger and stronger than the little box it came in originally. I will take great care to make absolutely certain it will not be damaged in transit. Also note that while this is a working unit, I am selling it without any option for returns, as it is a modular component I can not be responsible for potential damage caused from mishandling or improper power connections. ”
