The Uboat Suboctave is a very smooth sub-octave effect that generates a note one octave below the one you play. The Uboat Suboctave uses the same principle than other octavers to generate the output: it basically divides by two the frequency of the input signal, obtaining a sound one octave lower than the original. Nevertheless, the Uboat Suboctave uses a different method than the classic Boss OC-2 to create a circuit with a great tracking and responsiveness that generates a synth-like sound.
A quick note: to get the better results, the Uboat Suboctave should be used with single notes so it can properly track the audio and generate the octave down.
– The MIX knob lets you blend the generated sub-octave note with the dry signal, so you can go from just your original audio to the pure generated effect sound and everything in between.
– The DPDT alternates between the generated signal being in phase with the original audio (normal mode) and being 90º out of phase (synth mode).
The Uboat Suboctave Kit is based on ValveWizard’s project, check his website if you want more info about the project!
