The SY-1000 is a breakthrough creation machine that transforms your guitar or bass rig with limitless sound design options. This powerhouse music tool opens a bold new chapter in the legacy of BOSS guitar synth innovation, fusing decades of R&D with our latest software and hardware advancements. Backed by a cutting-edge sound engine, high-octane DSP, and evolved GK technology, the SY-1000 delivers the finest performance and most organic playing experience to date.

Three simultaneous instruments and premium processing let you craft any sound you can imagine—intense analog-style leads, warm pads, moving synth textures, modeled electric and acoustic tones, or all at once. And with freely configurable footswitches, outputs, and external controls, you can maximize the hardware for any workflow. Sonically vast and deeply expressive, the SY-1000 is an infinite well of inspiration, energizing your musical vision with endless possibilities.

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.
