For Sale: Korg X-911 Guitar Synthesizer

[7]

Korg X-911 Guitar Synthesizer This monosynth/effect unit is an unusual machine. I don't think there has been anything else made quite like it. Released in 1981, it is getting quite hard to find these in complete working order.

Firstly, the monosynth. It is triggered by audio input. It has a very Roland 303 sound to it. It can be triggered by a guitar or another audio source like a keyboard, bass guitar or even an acoustic instrument like a clarinet or tuba. Really anything monophonic piped into it.

The synth is cool but it's the effect unit (AKA "Synthe") that really makes this machine so desirable. The "synthe wah", distortion and envelope filters are all controlled by either the faceplate knobs or the incoming signal itself. The sweepable distortion just plain rocks. This thing works wonders on drum tracks, vocals or anything else you want to add an interesting effect to.
