The Octasynth’s origins date back to the early days of Subdecay and our love of old analog synth tone. Over the course of six years this effect was designed and redesigned more a dozen times until we got everything right – Perfection is not simply an issue of tone. In a stompbox it’s about simplicity and control.
The Octasynth is more than a simulation or an attempt to mimic analog synthesizers. It is an analog synthesizer. The heart and soul of the octasynth are two different effects both built around IC’s commonly used in analog synthesis. The first is an octave generator that converts your guitar into three square waves. The octaves then run through a second effect: A resonant low pass filter. 90% of the analog synth tones you are familiar with are just this – Raw waveforms and resonant filters.
The first temptation with any synthesizer effect is to make it complicated, so complicated that most people would never have the patience to use it. While this can make for a very fun (and expensive) toy, it becomes less useful or even frustrating if you can’t easily recall ‘that sound’ you were getting from it a few minutes ago.
Dynamics- Not only does the Octasynth track the note you are playing. It also tracks dynamics to control the filter. Use the DEPTH and RESONANCE controls to create in your face punch or resonant gurgles. Expressive controls let your playing shine through. The way you play a note has just as much effect on the sound as the note you play. The filter also completely turns off while you are not playing to eliminate sputter or other noises common with other octave effects.
Using it with Bass guitar:
The most common questions we hear about the Octasynth are from bass players. In the past we recommended not using this effect with bass guitar, but many bassists use it and love it. It really comes down to expectations. The pedal was designed with guitar in mind. The pedal can produce a full two octaves down which might be too much for the lower registers of bass guitar. Tracking may not be so great below the 5th fret. Playing around the middle of the fret board can create some great bass-synth tones.
The Octasynth is monophonic, so you’ll need to leave your diminished 9th jazz chords at home. The Octaynth just want’s to rock n roll!
