The Korena take

SY-1 brings 121 polyphonic synth sounds across 11 categories to an electric-guitar or bass pedalboard. Select a category and variation, then shape the result with Tone, Depth, Effect, and Direct controls. The pedal works from a standard 1/4-inch instrument input and includes separate routing options for blended or split signals: its send/return loop can combine synth sounds with drive pedals, while the send jack can operate as a direct output. Hold the footswitch to sustain the last synth sound while continuing with your regular guitar tone.
