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.

welcome party!

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.

Check out https://www.parasitstudio.se/
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.
