Turn your guitar or bass into a synth without needing a special pickup; the SY-1 tracks straight from a standard input. Dial in everything from lush pads and analog-style leads to deep sub-bass and filter sweeps, with a built-in dry/synth blend for mixing in your natural tone. Compact, rugged Boss build that fits any pedalboard and runs on standard 9V power. A great way to add serious synth textures to your rig without a rack or MIDI setup.
