Here's another original of mine, the "Raygun Youth Chaos Fuzz". It's a very synthy and totally insane octave fuzz - an aquired taste for sure, but noise freaks should like it. :)
It's loosley based on a circuit by Nicolas Collins from his excellent book "The Art of Hardware Hacking". A comparator turns the guitarsignal into a squarewave that triggers a Phase Locked Loop Oscillator. I could go on explaining how it works, but it's better that you just listen.
This circuit works best with the neck-pickup and tone turned down on your guitar. In the video i'm using humbuckers (Gibson SG) and i'm playing the same riff over and over so you can get a sense of how the circuit reacts in different modes. The pot called "disorder" slows down the PLL tracking and goes from fast to slow. When tracking is slow it's mostly noise... The first mode is straight analog comparator fuzz and thus not effected by the tracking control.
The name Raygun Youth Chaos Fuzz is a tribute to one of my favourite punk-bands. Yes, I know it's a bad pun, but I couldn't help myself... :) Aslo, the word Raygun is kinda fitting with some of the sounds it can make. Two thumbs up to anyone that understands the graphics play...
