Quick demo of a recently serviced and modded Jen Synthetone SX2000 italian mono synth.
CV/Gate and Fiter inputs were added, see the other video where I showcase the synth with external control. (

Recorded straight with no FX nor treatment.

The SX2000 is one of my favorite mono synth, I always had at least one in my setup. Just one oscillator but thaks to a ladder filter inspired by the EMS VCS3 it sounds very nice, it can be beasty and funky. Very simple architecture but some nice features like both VCF and VCA enveloppes can be set either in Attack Decay mode, Attack Sustain Release mode or repeat mode, rate being set by the LFO. This alone broadens the sonic range. The added CV/Gate kit (based on the Kentron one) enables this one to be interfaced by sequencers and/or modular synthesizers."

"Synth was serviced:
- fully recapped
- busbar and key contact were cleaned
- faders were cleaned and lubbed
- CV/GATE/Filter kit was added
- full calibration

It is in perfect working condition.
I have to point that the faders are not great on those synths, and though they were serviced they can be sometimes be hard to move. It's because the have a little play on the lever so when you engaged the move sometimes this play brakes them. Nothing dramatic but I just prefer to point it out, it's not Roland SH smooth faders. You just have to get how to grab them and then it's easy.
All the different SX-2000 I own had this issue and no cleaning or lube will ever make them perfect.

Cosmetic wise the synth has some wear but still looks more than decent."
