KORG X‑911

Vintage analog guitar synthesizer and signal processor

The KORG X‑911 is a rare monophonic analog guitar synthesizer and signal processor from around 1980, designed to convert a standard electric guitar signal into synthesizer‑like tones using an internal pitch‑to‑voltage converter. It works directly from a 1/4″ input — no special pickup required — making it a unique synth‑style instrument and effects unit. :contentReference[oaicite:3]{index=3}

The front panel is divided into two sections: the “Instrument” side with semi‑preset voices like Electric Bass, Tuba, Trumpet and Violin, and the “Synthe” side with selectable waveform tones (Pulse, Ramp, Square). These sections can be blended or used separately to create expressive analog sounds. With voltage‑controlled filter, portamento, interval selection and envelope controls, the X‑911 provides hands‑on tone shaping and creative performance options. :contentReference[oaicite:4]{index=4}
