Polyphonic Synth Pedal for Guitar and Bass

The BOSS SY-1 Guitar Synthesizer packs an impressive range of synth tones into a compact, user-friendly pedal. This fully polyphonic synth requires no special pickups or additional hardware, and there’s no need to dive into sound programming to get great results. Simply plug in your guitar or bass, choose from 121 inspiring sounds, and start playing. From classic analog textures to leads, basses, layered organs, lush pads, and arpeggiated sequences, the SY-1 offers massive creative versatility. With a built-in parallel send/return loop for easy integration with other effects, the BOSS SY-1 is a powerful and great-value solution for bringing synth sounds to your guitar or bass.

Over 100 synth sounds in a single pedal

Featuring exactly 121 sounds, the BOSS SY-1 lets you choose from 11 core synth types—such as leads, pads, and basses—each offering 11 distinct variations. No special pickup system or additional hardware is required, and the response is expressive and dynamic. Whether you’re adding a standout texture to a single song section or crafting full synth arrangements with your guitar, the BOSS SY-1 Guitar Synth pedal delivers inspiring sounds you’ll be proud to use.

Optimized for both guitar and bass

Designed for both guitarists and bassists, the SY-1 features dedicated modes that optimize pitch tracking for each instrument. Simply select guitar or bass on the mode switch and start playing. A blend control lets you mix your natural instrument tone with the synth sound, giving you precise control over how boldly the synth sits in your mix.

Send/Return loop for routing flexibility

Adventurous players at AJ’s Music & The Music Man love the SY-1’s send/return loop, which unlocks a wide range of creative options. The loop can be blended in parallel with the main synth output, making it easy to layer in external effects for added texture—try a slow phaser feeding a deep, fast tremolo for extra movement and depth. You can also use the send as a direct output, routing the synth signal to a separate amplifier for even more flexibility.
