Jen Electronics SX-2000 Synthetone

KeyboardAnalogMonophonic

Back in 1979, this Italian gem emerged from Jen Electronics as an affordable entry into analog synthesis, packing a surprisingly versatile punch in a compact 44-key package that's perfect for vintage enthusiasts chasing that raw, unpolished tone.

At its core sits a single VCO delivering sawtooth, pulse with PWM, and even noise options for gritty textures, feeding into a resonant ladder lowpass filter—reminiscent of the EMS VCS3—that can growl or sing with self-oscillation. Dual envelopes shape both the filter and VCA, switchable between AD, ASR, or repeating modes synced to the LFO's triangle or square waves, unlocking rhythmic pulses and evolving leads beyond its monophonic limits. Controls are straightforward with faders for most parameters, seven onboard presets for instant inspiration (bypassable for free tweaking), and a simple mono output, all housed in a lightweight, portable chassis that's seen plenty of road time despite its discontinued status.

Owners cherish its beastly, funky filter bite and innocent analog warmth for basslines and effects, often modding in CV/gate for modular integration, though the faders can feel gritty even after servicing—part of its charming vintage character.
