The Cloney Project VCS3 Clone

"100% faith full VCS3 recreation that has been professionally built by RAMCUR who built The Hornet Modular with PIN Electronics from a few years ago.
The main parts of this synth are from a kit from Germany's The Cloney Project. As you can see in the pictures, we upgraded a number of parts (solid shaft CTS pots all around being a significant upgrade to the feel and longevity) with premium parts as well as a number of period correct electronic parts where needed in the audio path. We also used the same spring reverb tank, meter and joystick pots that EMS used in their original design. Furthermore, the matrix is a custom Swiss made 16x16 Ghielmetti which is far superior than the the one that came with the kit. In fact, Ghielmetti make the best patch matrixes in the world. This synth sounds and feels amazing, it was built with no expenses spared.
Extras I'm including with the synth are a Kenton Pro Solo MK3 MIDI-CV converter, a custom 1/8" to Cinch-Jones conversion box, 3 extra Cliff knobs with chrome caps and a beautiful custom made dust cover. I'll also transfer my membership of The Cloney Project which will allow you to purchase their most recent kit which is high quality clone of the DK2 keyboard that matches this synth."
