The Raygun Youth Chaos Fuzz is a insane sounding fuzz based on the CD4046 Phase Locked Loop (PLL) chip.

A phase locked loop is basically an oscillator (VCO) that generates an output based on a external reference signal. In this case it's a guitar signal that the PLL tries to lock on to. I am writing ?tries? since a guitar signal is very complex and has alot of overtones and harmonies, making perfect tracking near impossible, thus creating very chaotic sounds.

This circuit works best with high output pickups. It is a gated circuit by nature of the comparator that turns the signal into a squarewave. If you are using single coils and need more sustain, try a boost or compressor in front. To improve tracking, use your neck pickup with the tone rolled off. I find that the most interesting sounds is up high on the fretboard.

3 from 5 Not for beginners

This build was a little troublesome to get done, mostly because the instructions were a little hard to understand. Ordered this for my buddy and he never got any sound out of it. I guess if you understand how Parasit designs their stuff and what theyre after then this is the sound mangler for you (:

4 from 5 great sound, not the easiest build

The PCB is very nice and easy to work with, but getting the mode switch and pots lined up and on the same height is tricky, as I found out when I broke one of the pots getting it into the enclosure. Soldering the pots high on their legs and putting some washers on the pots helps to have them sit securely.
The sound is great, crazy chaos fuzz and glitches.
I ordered two PCBs and one of them is a v1.1, which has the optional CV input - highly recommended if you have the outboard equipment to drive it!

5 from 5 Easy to build and fun as hell!

If you are thinking about what you are doing, youll have no trouble to assemble it. It took me three hours to finish it.
Regarding the sound, it is fun, fun, fun! The first mode is a nice fuzz but the other theree are the real adventure! I highly recomend it to anyone willing to step out of the box and explore something new!

4 from 5 Great PCB and parts, instructions could use some work

I was happy to see that the PCB was extremely clear and that the supplied parts were easy to use (long-legged pots, chip holders, etc.)

The only problem is Parasites documentation leaves out some information and is vague about certain things (especially around the footswitch and LED installation.)

Generally happy. ;-)
