Expressive Synth Sounds, No Programming Needed
The SY-1 transforms any guitar or bass into a versatile synthesizer that’s fun, inspiring, and ready to play. Backed by advanced tech first developed for the SY-300, this super-cool pedal delivers a huge selection of analog-style synth sounds while occupying minimal space on your board. What’s more, all the sounds are polyphonic, allowing you to play both single notes and chords.
Plug-and-Play and Latency-Free
The SY-1 can be used with any guitar or bass via a standard 1/4-inch cable, providing an easy, plug-and-play experience. Thanks to custom DSP and the latest BOSS innovations, the SY-1 offers latency-free performance that’s a natural extension of your instrument, letting you to play freely and organically without altering your normal technique in any way.
A Universe of Synth Sounds Inside
With its 11 categories and 121 total sounds, the SY-1 puts an enormous array of synth colors at your fingertips. Expressive leads, sweeping pads, layered organs, fat basses, and more are all on tap, plus a variety of rhythmic synth patterns that are a blast to jam with. And with the grab-and-go Tone/Rate and Depth knobs, you’re able to adjust any synth voice just how you like, including changing the pitch on some sounds.
At Home in Any Rig
As a standard BOSS compact, the SY-1 drops into a serial pedal chain like any other stomp. But with the send/return loop and dedicated mix controls, it’s also possible to blend one or more pedals in parallel with the SY-1’s synth voices. For example, you can patch drive pedals in the loop, and then send the combined output to mod, delay, and reverb pedals for overall processing. The send can be used as a direct out as well, enabling you to route synth and guitar sounds to separate destinations.
Enhance Performances with Real-Time Control
The SY-1 offers a numbers of ways to make your synth performances even more dynamic and expressive. Pressing and holding the pedal switch sustains the last-played synth sound, allowing you to jam with regular guitar over the top. You can also connect an external footswitch for tap tempo and octave-shift effects, or plug in an expression pedal for continuous Tone/Rate control.
