Industrial Music Electronics Bionic Lester 1873 MK III

“The filter is between very good and excellent condition – filter B has wobble on the cut off knob – which is the only blemish so to speak.

Great gnarly tones for days.

Bionic Lester Mark III is a two channel 12dB state variable digital filter inspired by the best of late-1990s “virtual analog“ filters. Each filter section has three CV inputs.

The Mark III preset system stores eight fully programmed panel setups, instantly recalling everything under the harshest demands of performance. The Morph mode allows smooth fading between all of these presets. The controls are arranged for maximum tweakability and the OLED display displays the cutoff frequency in hertz, resonance amount, and filter type.”

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…”
