Our Take
The SY-300 is undeniably one of the most innovative products ever launched by BOSS. Before it arrived, guitar synthesis generally meant specialised pickups, additional hardware and compromises in feel or tracking. The SY-300 removed those barriers entirely. You simply plug in and play.
What continues to impress players years after its release is how responsive it feels. The synth tones react to picking dynamics, vibrato and articulation in a way that feels connected to the instrument rather than sitting on top of it. That's why many guitarists who normally dislike guitar synths end up connecting with the SY-300.
One of the most impressive features is that it empowers you to fully embrace your guitar identity without compromise. Some synth pedals completely replace the sound of the instrument. The SY-300 excels at blending synthesis and guitar together, creating hybrid sounds that remain expressive and playable. Pads can sit beneath clean chords, filters can animate rhythm parts, and synth textures can be layered with lead lines without losing the character of the guitar.
For ambient players, progressive musicians, worship guitarists, soundtrack composers and experimental sound designers, the creative potential is enormous. Yet it's equally capable of delivering straightforward synth basses, lead sounds and electronic textures that slot naturally into modern productions.
While newer synth pedals have entered the market, the SY-300 still occupies a unique place because of its depth, flexibility and ability to make synthesizer sounds feel genuinely musical under a guitarist's hands.
