"Excellent condition. Includes black gig bag. The bag is a bit oversized for this unit but will get you from point A to point B. This synth will be packed with extra care inside the bag for shipping.

The Poly Evolver is Dave Smith’s four-voice hybrid masterpiece, combining two analog and two digital oscillators per voice with Curtis analog filters, deep modulation options, and four independent 16-step sequencers. Its knob-rich panel invites hands-on sound design, from evolving textures to aggressive leads. Originally introduced in the mid-2000s, the Poly Evolver remains one of the most powerful synths of its era.

This unit, originally owned by Jordan Rudess of Dream Theater, is in spectacular condition. A rare opportunity to own a landmark instrument that bridges the analog warmth of classic Sequential with the innovation that launched Dave Smith Instruments.
