The Verdict
The BOSS SY-300 marks a watershed moment for guitar synthesis. Previous attempts ranged from shaky to downright unreliable, but BOSS has finally delivered an instrument that makes guitarists seriously want to occupy keyboard ground.
The polyphonic approach using guitar signal processing is the breakthrough. Instead of struggling with tracking lag, the SY-300 harmonically processes your actual guitar signal into sine, saw, square, pulse, triangle, and noise waves. This means your playing dynamics directly affect the synthesis result—attack, dynamics, and expression matter exactly like they do on your guitar. No special pickup required, no hardware modification needed.
Three oscillators routed through multiple effects chains give you staggering sonic range. You can use just the input signal as a multi-effects processor if synthesis isn’t your moment, or dive deep into user-generated patch databases for inspiration. MusicRadar gave it a perfect 5.0 stars, calling it the dawn of a new era for guitar synthesis.
The learning curve is real—this isn’t plug-and-play intuitive. But if you’re willing to spend time with the Tone Studio software and understand basic synthesis principles, the SY-300 opens entire sonic territories. For adventurous players seeking to expand their instrument’s scope, this is genuinely Legendary-tier.
