Here's a cool sounding Ringmod/octave up
The original needs a external oscillator connected to the B input.
With no oscillator it sounds more like a octave fuzz
But I figured that it would be much more usable with a built in oscillator.
So I made this daughterboard circuit that can be switched on/off.
It also gates the carrier signal when not playing = no carrier bleedthough! :)
More info and schematic
here. I will post my finished build soon, with sound samples
