The Boss SY-200 transforms your guitar or bass into a versatile analog-flavored synth, ready to infuse your music with dynamic, compelling, and evocative new voices. This streamlined stomp gives you 171 total sounds organized in 12 intuitive categories, along with adjustable parameters for customizing the tone and response. And with 128 memory locations, you're able to store your favorite sounds and instantly recall them while performing.

Build Custom Sounds Fast

With the SY-200's informative display and hands-on controls, it's quick and easy to call up sounds and balance the direct and synth levels. All the preset synth tones have been dialed in by the BOSS engineers to be inspiring and playable right away. But if you want to go deeper, you can tweak three different parameters for each sound via dedicated knobs.  

Flexible Connectivity

The SY-200 smoothly integrates into your setup in a variety of ways. Patch it in your chain like a regular pedal, or use the send and output jacks to route synth and straight guitar sounds to different destinations. And with the send/return loop and level knobs, it's possible to craft unique hybrid sounds by blending one or more pedals in parallel with different synth voices.

Powerful Real-Time Control

The SY-200 provides a massive range of control options while taking up minimal space on your pedalboard. Two customizable footswitches offer multi-functional operation with press-and-hold functionality, allowing you tocontrol 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.  

Plug-and-Play and Latency-Free

You can use the SY-200 with any guitar or bass--just plug in with a standard 1/4-inch cable and start creating. Thanks to custom DSP and the latest BOSS innovations, you'll enjoy latency-free performance that's a natural extension of your instrument, letting you play freely without altering your normal technique in any way.
