Key Info
Boss SY-1 Synthesizer is a Synthesizer Effects Pedal that features a wide range of synth sounds to boost your performance

More choice than ever before

Synth pedals don't usually offer you as much as the Boss SY-1. But then, there aren't many pedal makers out there who can cram such a huge range features into a single, compact box. This excellently expressive pedal includes an enormous selection of 121 different synth sounds to choose from. Whether you're after analog synth tones, layered chords, lead arpeggios, or full, organ-like soundscapes - the SY-1 has got you covered. With such an immense amount on offer, you'll never need another synth pedal.

Intuitive, easy-to-use controls

Achieving the perfect synth tone has long been a time-consuming, often complicated process for guitarists. Many pedals on the market require extensive programming to create the right voice for your music, and some even necessitate installing special pickups into your guitar. With the Boss SY-1, that isn't the case. It's been designed with usability in mind, featuring an incredibly simple interface that makes it quick and easy to find your perfect tone. No stressful fiddling. No awkward setup. Just stunning synth sound from the moment you plug in.

The best in performance

Impressive synth effects are nothing if your audience can't hear them properly. So Boss have made sure the SY-1 is capable of delivering the absolute maximum in clarity and performance. With innovative, latency-free operation, you won't have to alter the way you play - the SY-1 will let you play freely and naturally. And every note will be crystal-clear.

That's not all.

Every synth sound loaded into the SY-1 is polyphonic, meaning you can use the pedal for both lead notes and rhythmic chord playing. A parallel send and return loop means you can easily use your other pedals alongside the SY-1, delivering even more tonal options. And real-time control, including the "press and hold" function that lets you sustain the last synth note you played, makes on-stage use a breeze. This is the ultimate addition to your pedalboard.


  • LEAD 1/2 - a wide range of sounds suitable for single-note soloing.
  • PAD - full tones that work great with chords, from layered pads to synth brass and more.
  • BASS - fat synth bass sounds, including filtered and sub-octave tones.
  • STR - classic analog-style strings, including layered voices and sweeping textures.
  • ORGAN - a large selection of organ sounds, including many with rotary-style modulation.
  • BELL - percussive synth sounds with metallic resonance.
  • SFX 1/2 - a variety of synth sound effects, including explosive one-shot sounds, animated pitch/filter voices, and more.
  • SEQ 1/2 - pulsating sounds with rhythmic pitch or filter changes.
