The TWA Great Divide 2.0 is an all analog octave divider with 5 independent voices. Each voice can be mixed continuously with their own volume slider, producing classic sub octave effects , octave up clang, and multi-layered synth tones with a fat bottom end and exceptional analog tracking.
Totally Wycked Audio use proprietary technology to generate the SUB and SYN voices, which can easily turn your guitar into a bass or old school synthesizer. Both voices have a wide array of tones and textures plus selectable intervals from one octave below to 2.6 octaves for extra complexity and harmony. The SNY voice also gives you 4 selectable waveforms for producing anything from 8 bit video games sounds to growling monophonic synth.
