Critic Reviews

Jen Synthetone SX1000 [Retrozone]

soundonsound.com

The Jen SX1000 Synth is a quirky piece of synth history that offers a mix of charm and limitations. While its simplistic design and lack of frills may not impress the modern musician, it holds nostalgic value for its clean sound reminiscent of the Korg 700. The synth's unique oscillator and pulse-width modulation are highlights, but its limited modulation capabilities and multi-triggering mode are drawbacks. Despite these flaws, its affordability makes it an intriguing option for those looking to experiment with vintage sounds on a budget. Overall, it's a niche find for synth enthusiasts with an appreciation for retro charm.
