Revolutionary guitar synthesizer with polyphonic tracking without special pickup

With the Boss SY-300 Guitar Synthesizer, the Japanese effect specialists present a revolutionary guitar synthesizer that allows polyphonic and latency-free tracking with any standard guitar. A special pickup with the appropriate cable is no longer necessary to enjoy first-class synth sounds.

Three synthesizers and step sequencer

At the heart of the SY-300 are three powerful-sounding synthesizers with polyphonic signal processing, which form the basis for extremely versatile timbres. In addition to the ability to control the waveform of the oscillators, various filters and modulations can also be used for sound processing. A step sequencer with 16 steps and tap tempo is also on board to generate melodies and arpeggios with only one played note. In addition, it is possible to alienate the guitar's own sound with the oscillators and synthesizers.

Extensive Effects

The Boss SY-300 is also equipped with four effects processors that can be used simultaneously to take your sound to the next level. The synthesizer offers a choice of countless overdrives, distortions, delays and reverbs, slicers and modulation effects. All of the SY-300's effects can also be used as classic guitar effects, so there's no limit to what you can do with the pedal. 

Editor software and audio interface

The SY-300 Guitar Synth can be connected to a PC or Mac via USB for convenient sound creation and archiving using the free Boss Tone Studio software. In addition, the SY-300 can be used as an audio interface to record the first-class synth sounds directly in the DAW.

Extensive connections

Last but not least, the SY-300 Guitar Synthesizer from Boss convinces with extensive connectivity options, with which the effect unit can be easily integrated into any rig. The Thru output sends the unprocessed input signal to another effects chain or a guitar amp. In conjunction with the return jack, the thru output serves as a send for the serial effects loop, allowing you to integrate your own effects units into the signal path. Two sets of stereo outputs allow the SY-300 to be removed, and the pedal can also be controlled via MIDI.
