“Olivia’s Vintage would like to present this 1980’s Korg X-911 analog Guitar Synthesizer. It’s triggered by any instrument using regular input and output jacks. It’s a very unique synthesizer and 100% working. It’s in great shape with only some minor cosmetic wear.” Click here to search for synths on eBay

“This is untested unit. It powers up and I got the input sound on the output, however no other testing was completed.” Click here to search for synths on eBay

“Partially working with faults!

Instrument side:
Elec Bass LED always on (doesn’t Cancel) No sound either from this preset.
Tuba never switches on, so no response from this one either.
the other 4 work as intended, including trim pots.

Synthe side:
LEDs will light & cancel, but none are sounding.

I have a feeling this will centre around the filter chip rather than the buttons. Similar to the common fault in the Korg Delta. The parts are still available.

The left hand side of the panel is fully working, input, portamento/ interval/ tune/ octave all 100% on the 4 working voices. Still great fun to be had with this alone! Glitchy, Prog-type fun & Octave effects a-plenty!

Synthe filter knob not working, again pretty sure this is related to the synthe side. Possibly these tones go through the filter chip & the instrument side is filtered by resistors etc, as you have no control over those.”
