Korg RK-100S Keytar - 37-Key Shoulder Synthesizer with Built-In MMT Engine (Red)

The RK-100S is Korg's modern revival of the RK-100 remote keyboard that first appeared in 1984. Where the original required an external sound module, the RK-100S carries a built-in analog modeling sound engine, making it a self-contained performance instrument that steps out from behind the keyboard stand.

This example wears the Red finish and is offered as a player's piece. It shows honest cosmetic wear from stage and studio use, while all electronics function correctly.

== WHY THIS KEYTAR ==
The RK-100S puts a full analog modeling synth, a vocoder, an arpeggiator and two ribbon controllers into a shoulder-mounted body that is genuinely comfortable to perform with. Battery operation means it works anywhere, and the A-H favorite buttons make patch changes instant on stage. For players who want the classic keytar silhouette with a modern engine behind it, this is a practical and stage-ready choice at a player-grade price.
