BOSS SY-300 Guitar Synthesizer

Bring a new world of tone creation to your guitar with the BOSS SY-300 – a sophisticated guitar synthesizer pedal that offers dizzying control over your sound! 

Unlike other guitar synths that require a special pickup, the SY-300 can be connected up with any guitar or bass by means of a regular ¼ inch TRS jack guitar cable! In fact, it works with any electronic instrument with a ¼ inch jack connector, making it perfect for multi-instrumentalists or studio bands!

You can even apply the SY-300's impressive filters – as well as the LFO controls - to your natural guitar tone, opening up an even greater palette of sound.

The rich, analog-style polyphonic synth sounds might steal the show, but perhaps just as impressive is how the SY-300 operates with zero latency, offering immediate feedback for the most fluid and musical experience possible.

From unique lead textures to rich, evocative soundscapes, the SY-300 brings untapped dimensions of inspiration and creativity to your music. Three simultaneous synth sections and four effects processors enable rich, dynamic, and diverse sound creation while 70 ready-to-play preset patches and 99 user patches for storing custom sounds make it easy to recall your favourite tonal adventures!

Create and archive sounds on your computer with the BOSS Tone Studio editor/librarian, download new sounds at BOSS Tone Central Download and share Livesets at BOSS Tone Exchange.

The SY-300 features a Graphic LCD display, three assignable footswitches and dedicated on/off footswitch. There’s even a step sequencer (with tap tempo control) for creating dynamic melodies and arpeggios simply by playing a single note on your guitar! And with the cool Blender function, you can instantly mix and match synth settings from other patches to discover inspiring new sounds with no heavy lifting at all.

The SY-300 is equipped a USB audio interface to capture audio tracks directly into music production software on your computer. You can record the SY-300’s synth and effects sounds, or just monitor them while recording a dry signal. Then, feed that signal back into the SY-300 to “re-synth” the sound and create the perfect tone for your mix. You can feed other tracks from your DAW into the SY-300 as well, processing them with the synth engine and effects to create cool new sounds for your productions.

3. We always refund the payment according to how the original purchase was made and aim to do so within 72hrs of the return being received by us.

4. Returned goods are liable for a restocking fee of 15% towards handling and repackaging if the order is not returned in its original, unopened packaging. This charge will be subject to our inspection of the returned goods.
