This synth sold on 12-9-2025.

Sold: Korg Prologue 8 49-key analog synthesizer in excellent condition, fully tested and working perfectly. Sale includes the synth, 8ft high quality power cable, and the original box (but not the original foam inserts). Note, the original box is a little worn. We'll supplement packing materials and double-box for safe shipping.

Details:

Fully cleaned, tested, and verified.
All tacts, pots, encoders, wheels, and keys are responsive and 100% functional.
There are a few extremely minor blemishes. Mostly light marks on the wood sides and one or two on the rear panel. We'd rate it near-mint / excellent. Please review the photos carefully. We've done our best to capture the cosmetic condition accurately.

The Korg Prologue 8 is a professional-grade 49-key analog synthesizer offering eight voices of polyphony, dual VCOs, a digital multi-engine, and built-in DSP effects. Combining analog warmth with digital flexibility, it features a bi-timbral architecture, studio-quality reverb and delay, and a user-customizable oscillator section that supports third-party development. Its powerful 16-slot modulation matrix, OLED oscilloscope, and aluminum and wood construction make it both a performance-ready synth and a deep sound design tool. This unit is in excellent condition and ready to anchor any stage or studio setup.
