Are there such things as Lunetta effects pedals?

I've just ordered a few CMOS chips and I want some things I can use to affect a sound made with guitars/synths, so I'm wondering if there's anything out there that combines those two things.

Converting the guitar signal to a square wave will allow it to function as an on/off digital signal. Here are a couple examples from nicolas collins book, using a 4049 for tremolo and octave down. Cd4049ube would probably be ideal for guitar use. Tim Escobedo's PWM and Ugly Face would be another good example using a lm386 to square the signal. http://www.jiggawoo.eclipse.co.uk/guitarhq/Circuitsnippets/snippets.html
The MXR Blue Box used a cmos flip flop for the octave down.

As far as conventional guitar effects go tremolo, octave up/down, fuzz/distortion/overdrive and faux ring modulation would all be fairly easy to achieve with cmos ics.

hell yeah, tremolo! I'd forgotten that I'd read Handmade Music until just now.

I posted a circuit for a CMOS based phaser here.

This is a suboctave harmonic generator. The input and output should be usable to interface to other CMOS circuits as well.

For his guitar synths he mainly use CMOS ics.

this fx pedal is insane. I just built it and put it at the tail end of the newest lunetta noise machine im working on.

It's based around a 4069 and, oh boy, does it sound super cool. Brings out some very cool harsh digital noise - if that's your cup of tea.
