Title: Party Mammoth * Demo added
Post by: Guitarmageddon on March 26, 2015, 06:14:35 AM
A Woolly M***moth Fuzz, but with a second stomp for "Party Mode"- which adds a Logan 5 ring-modulator.
Ring modulation can also be controlled by waving a hand or a foot over the optical sensor.

Transistors are nice BC109s in the fuzz. Guts a real mess I re-worked them a few times. Originally it had a feedback loop, then I added the ring mod but found I had carrier noise issues. Shielded the input line and rearranged things now it's nice and quiet.

Oh... and the party hat lights up when the Ring mod is active.

"Ring modulation can also be controlled by waving a hand or a foot over the optical sensor."

Sweet! And those guts go with the theme of the pedal: controlled chaos.

That LPR for the modulation is a pretty trick idea.  How does it work on a stage, under ever-changing lights?  Might add an extra element of interest.  :)

As always, that's yet another amazing etch and rad circuit.

Yes, it's always going to have varying results depending on the environment. It's in series with the Frequency pot so it has some range of adjustment. If your light show is synchronised to your music in some way it definitely could get interesting.

I don't have to ship it for a little while, so I'll see what I can do.

By "mod" I meant ring modulator. The circuit is Culturejam's  improved "Thing Modulator," originally designed by Tim Escobado. With a bit of searching you should be able to track it down. ;)
My vero layout is attached. Using the right IC is crucial, they can be a little tricky to locate- I have a bunch if anyone wants some.
