Boss SY-1 - Journey to New Sound Horizons!
With the SY-1, it’s never been easier to combine your creative potential with the legendary BOSS guitar synthesizer technology. The SY-1 is an exceptionally expressive tool with 121 highly responsive sounds housed in a BOSS compact pedal that fits seamlessly into any setup. And the best part: it operates as simply as a conventional stompbox. This way, you don’t need to be an experienced synthesizer programmer to take your music into completely new sonic realms.
Expressive Synthesizer Sounds Without Programming
The SY-1 transforms any guitar and bass into a versatile, inspiring, and always ready-to-play synthesizer with maximum entertainment potential.
Based on advanced technology originally developed for the SY-300, this cool pedal offers an enormous selection of analog-style synthesizer sounds while taking up minimal space on your board. Moreover, all sounds are polyphonic, allowing you to play both single notes and chords.
Plug-and-Play Without Latency
The SY-1 connects to any guitar or bass via a standard 6.3 mm jack cable and is ready to play immediately. Thanks to the custom DSP and cutting-edge BOSS innovations, the SY-1 delivers a latency-free performance that feels like a natural extension of your instrument. This lets you play freely without adjusting your technique.
A Whole Universe of Synthesizer Sounds
With its 121 sounds across eleven categories, the SY-1 offers a vast palette of synthesizer colors—playable right on your fretboard. Available are expressive leads, shimmering pads, layered organs, massive basses, and more, plus a variety of rhythmic synthesizer patterns that invite extraordinary jams.
You can also instantly shape each sound to your liking using the accessible tone/rate and depth controls, and for several sounds, even change the pitch.
At Home in Any Rig
Thanks to the BOSS compact standard format, the SY-1 integrates effortlessly into any serial pedal chain. With its send/return loop and dedicated mix controls, you can blend one or more pedals in parallel with your synthesizer sounds.
For example, you can patch drive pedals into your loop and further process the combined output signal with downstream modulation, delay, and reverb pedals. Additionally, the send can be used as a direct out to route synthesizer and guitar sounds to different destinations.
Expand Your Performances with Real-Time Control
The SY-1 offers numerous ways to make your synthesizer performances even more dynamic and expressive. Holding down the footswitch sustains the last played synthesizer sound while you play over it with your normal guitar tone.
You can also connect an external footswitch to control tempo and octave-shift effects, as well as add an expression pedal to continuously control the tone/rate knob.

Transparent sounds, unobtrusive and differentiated control. Certainly not natural but close. Recommended purchase.

Since buying the accessory cables and the pickup was too much work for me and I had to drill holes in the guitar, I bought a keyboard.
Great device
