Quad sub-octave generator and ring modulator

There are many ways to fatten-up a thin signal, but imagine adding an adjustable mix of four full octaves of rich lower subtones to your original source!

(Talk about radical?) With a second input and the flip of a switch, this module engages four internal ring-modulators which each use one of the four sub octaves the module generates as a carrier against the modulation input.

Inspired by an ancient circuit in ElectroNotes, and then expanded upon by Designer Paul Schreiber into the fiercesome MOTM 120 module - This Modcanian adaptation of the Sub Octave Multiplexer can easily transform the sound of a simple flute into a tuba, or if the mood strikes you then, perhaps into a wailing wall of heavy metal thrash guitars! Not for the faint of heart
