BOSS SY-200 Synthesizer Effects Pedal
The SY-200 represents a more expansive, feature-rich option with 128 memories and a large footprint of synth sounds. This pedal extends BOSS’s synth lineage into a panel that supports complex voice shaping, making it ideal for performers who require a broad sonic palette and robust preset management on stage or in the studio.

Buying Guide
What should you look for in a guitar synth pedal?
Key features include polyphony, ease of preset management, tracking accuracy, and real‑time control options. Decide whether you need live performance versatility, studio‑friendly recall, or aggressive, edgy synth textures. Consider the pedal’s footprint, power needs, and routing options (send/return, MIDI I/O, expression pedal compatibility).
How to match a pedal to your playing style
- For on‑stage flexibility: choose pedals with quick preset access and sturdy build, like the MOOER E7 or BOSS SY‑1.
- For studio sound design: prefer deeper synthesis engines and large memory banks, such as the BOSS SY‑200.
- For classic synth tones: mono or vintage‑style voices work well, as with Electro‑Harmonix Bass Mono Synth.
- For experimental textures: look for shifty envelopes, phase modulation, and expressive input options, as seen in the MXR Bass Synth.
Connectivity and future-proofing
Check for MIDI I/O, expression pedal compatibility, and loop routing to integrate with other effects and keyboards. A dedicated bass or guitar input should be clearly labeled, and a robust power supply reduces noise and dropouts during performances.
Practical setup tips
- Isolate the synth pedal in a dedicated chain or loop to manage noise and phase alignment.
- Set up presets to cover common songs or sections—verse, chorus, effects break, and outro—you’ll save precious stage time.
- Test with your typical guitar pickups and volume settings to verify tracking accuracy and tonal integrity.
