I took the SY-1 for a quick spin yesterday. It's pretty cool! No hex pickup needed, 121(!) different sounds, pads, strings, bass, lead... KILLER sequencer patches. You can screw heavily with all of them thanks to the tone, rate and depth knobs. There's a freeze function, expression control... Boss have packed a ton into this pedal. And the look hasn't changed since the 80's! Sweet as. More to come.
