Used Boss SY-1 SYNTHESIZER Synthesizer Pedal

This Boss SY-1 Synthesizer turns a standard guitar or bass into a powerful synth instrument without requiring special pickups or complex setup. Packed into a familiar Boss compact enclosure, it offers a wide range of synth tones spanning classic leads, deep pads, punchy basses, and expressive textures, all accessible through an intuitive control layout. The addition of direct signal blending keeps your original tone present if you want clarity alongside the synth sound.

Boss designed the SY-1 to track fast and accurately, making it feel immediate and playable rather than laggy or artificial. The onboard effect section and multiple sound categories allow for serious tonal variety, from subtle color to full-on synth transformation. It has become a popular choice for guitarists and bassists who want to explore synth territory while keeping their existing rig simple and pedalboard-friendly.

This pedal has been tested thoroughly in store to ensure proper operation.
