A New Era of Guitar Synth Innovation

The SY-1000 is the most advanced guitar/bass synth we’ve ever made, hands down. Custom DSP delivers six times the processing muscle of the SY-300, and the newly developed sound engine leverages the power of GK independent string processing for ultra-articulate performance, lightning-fast response, instantly variable tuning, sound panning/layering, and much more.

Deep Sound Design Tools

A standard SY-1000 patch includes three simultaneous instruments—each with a number of distinctive types to choose from—and you can combine and layer them for an endless range of sounds. Fed by the 13-pin GK input, every instrument offers an extensive set of parameters for tone shaping, mixing, and tuning. A normal ¼-inch input is available as well, letting you blend regular guitar/bass pickup sounds alongside the three instruments.
