  • ARPEGGIO — Generate rhythmic arpeggios based on the notes you play.

Create Custom Sounds Easily

It’s fast and simple to call up sounds and balance your direct and synth levels, courtesy of the Boss SY-200’s intuitive display and hands-on controls. Boss' engineers have programmed a huge amount of preset synth sounds that are instantly energising and playable, but if you want to go deeper, you can tweak three different parameters for each sound via dedicated knobs.

Flexible Connectivity

Thanks to an abundance of inputs and outputs, Boss' SY-200 pedal can smoothly integrate into your existing setup. Patch it in your chain like a regular stompbox, or use the send and output jacks to route synth and straight guitar sounds to different destinations for unique hybrid tones. And with the send/return loop and level knobs, it’s possible to blend one or more pedals in parallel with different synth voices!

Powerful Real-Time Control

In classic Boss style, the SY-200 provides plenty of real-time control despite its compact, pedalboard-friendly proportions. Boasting a pair of customisable footswitches which offer multi-functional operation with press-and-hold functionality — these allow you to control synth on/off, memory scrolling, pitch bend, synth hold, and more.

Expanded control is possible via external footswitches or an expression pedal, and MIDI I/O is also available to interface with other MIDI-equipped pedals and devices like the ES-8 and ES-5 loop switchers.
