Building upon the Boss SY-1 guitar synthesizer pedal, this massively impressive synth music machine captures all the magic of the original plus so much more. The Boss SY-200 is centered around analog-inspired polyphonic tones that turns any guitar or bass into a formidable pseudo-synthesizer. Twelve onboard analog-style synth modes with many variations on each make the library of the SY-200 a deep catalog of synth tones. Once you've found your synthetic sweet spots, over one hundred preset saves slots allow for recall. Additional features including a parallel send/return loop allows for easy integration with your other pedals, expression pedal connection, and full MIDI I/O capabilities with 3.5" TRS jacks (available separately). The Boss SY-200 is both a powerful digital synthetic engine for endless experimentation and an instantly playable pedal for your next composition. Used- Very good condition. Includes Original Box.
