Available as an assembled Module and as a DIY project.
This Module is currently available.
As the name suggests this module can produce sub frequencies of -1 and -2 octaves relative to the square wave signal provided at the input jack.
But this is not just a simple SUB generator. It also has a little mixer that will let you add different levels of -1 and -2 octave signals to the original square wave. You can select the -2 octave signal to be a square wave or a pulse wave.
The module has individual outputs for the mixed signal, the -1 octave and the -2 octave.
This little modules can produce enough timbral variation to make you bass sound exciting.

These merchants probably sell this module. Huh?
