BOSS SY-300

Access Expressive New Sounds via a Standard 1/4-Inch Input

With the SY-300, tapping into BOSS’ legendary guitar synth technology has never been easier. While our other synth products require a special GK pickup and 13-pin cable to access synth voices, the SY-300 can be used with any guitar via a standard 1/4-inch cable. Powered by ultra-fast DSP and newly developed innovations from the BOSS engineering team, the SY-300 performs its amazing synth magic in real time, with no lag whatsoever. This delivers a latency-free playing experience that’s a natural extension of your normal guitar, letting you to play freely and organically without altering your technique in any way.

A True Analog-Style Synth for Guitar

The SY-300 features a powerful polyphonic synthesis engine with three separate sections, bringing a limitless range of fresh tones to your arsenal. Just like a keyboard player with a classic analog synth, you have complete creative freedom to build sounds with a full palette of synthesis parameters—select different wave shapes, tweak them with filter, amp, and pitch controls, modulate them with LFOs, and layer oscillators for rich, complex tones. 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.

Powerful Control Options and Versatile Connectivity

Controlling the SY-300 while performing is simple. Using the four built-in footswitches, you can bypass the synth sound, scroll through patches, and control three different parameters of your choosing per patch. Two external footswitches or an expression pedal can also be connected for even more real-time control if needed. The Thru output lets you to send your dry guitar sound directly to your pedals or amp, or it can be used along with the Return jack as an effects loop. Dual output pairs (Main and Sub) offer assignable signal routing options to integrate with any setup, while MIDI In and Out/Thru jacks are provided for interfacing with switchers, drum machines, and other MIDI gear.

USB Interface for Computers

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. The SY-300’s USB connection also allows you to build and organize patches with the dedicated BOSS Tone Studio editor and download new patches from the BOSS Tone Central website.

Awesome for Bass
I play bass at church and there are so many songs nowadays with big synthy bridges. This pedal is amazing for it. I actually keep it on the Guitar setting bc I think it sounds better than the bass setting and it keeps the low end full. Great pedal.

Sul suono non c'è nulla da dire, è semplicemente incredibile. Quello che invece bisogna capire prima di acquistarlo visto il prezzo, è il contesto dove impiegarlo. Un pedale che se usato con parsimonia puo fare la differenza. Come sempre consegna puntuale.
