Octo-Cat

12 March 2018

This one is a chopped OC-2 clone - on a PCB called "The Low Down" by DC6FX. It does octave down, with volume for the clean and octave down signals.

I wasn't really happy with the 'clean' signal path in this schematic, as it ended up clipping quite badly at the first op-amp. So I ended up removing the volume pots, hard wired it to have no clean signal, and then made a small blend circuit to mix between a proper clean and the octave effect. Sounds much nicer to my ear.

I thought I'd measured everything three times, but when I put the switching and blend circuit into the box, it was about 2mm too high. Dammit. So I pulled that apart, reversed the switch and a few components, and got it to fit.

Graphics are a blended octopus with cat. I dunno, seemed appropriate. And I think this is the most expensive knob I've put on a pedal - it was about $7. Given that there was only one knob, I figured I could splurge on it, while still maintaining the pedal to knob cost ratio. :-)
