Octasynth Guitar Octave Synthesizer Pedal


With 3 square wave octaves, the Subdecay Octasynth redefines guitar synthesizer pedals. The Subdecay Octasynth converts the guitar signal into 3 square wave octaves that are then run into a resonant filter. This culminates in a wide variety of vintage analog synthesizer tones that react uniquely to your guitar and playing style.

The Subdecay Octasynth is monophonic so it only reacts to one note at a time and the tracking depends on playing style and seems to work best with the neck pickup. Power chords will sometimes create a glitchy, musical effect and palm muted single note runs can go anywhere from filter sweep to sub bass bumps.

The Subdecay Octasynth is the perfect base for creating huge synth sounds when coupled with other effects like fuzz, delay, and reverb.  Sweet sounding and easy to use, the Subdecay Octasynth is the perfect companion to those guitarists wanting to reach out a little more into the electronic music genre.

By the way, the Subdecay Octasynth is all analog!
