BOSS SY-300 Guitar Synthesizer

The Sound Revolution from Boss!

The SY-300 from Boss delivers polyphonic and above all latency free synthesizer sounds with any conventional guitar. Special GK pickups and the respective cables with 13-pin connections are not required!

Three simultaneous synthesizer sections form the foundation of the sound, which can then be manipulated through various filters and modulation effects. A step sequencer with 16 steps and tap tempo function is also onboard.

Next to the elements of a synthesizer, the SY-300 also offers the processing of the regular guitar signal, just like a conventional multi-effect. Included are of course overdrive and distortion pedals, slicers and many more. Both forms of sound manipulation can be used at the same time.

Together with normal music production software, the SY-300 Guitar Synthesizer can also be used as a USB interface. Various recorded signals can be “re-synthesized” at any time. In addition, the USB connection provides a comfortable way to create and manage personal presets with help from the Boss Tone Studio software.
