Flying Guillotine Fuzz

EDIT 2014-08-19
I added a single layer PCB layout to the bottom of the post that fits better in a 1590B. Effects layouts also made an excellent perf and PCB layout, check it out at: http://effectslayouts.blogspot.se/2015/07/flying-guillotine-fuzz.html

Here's a fuzz circuit I made up about a year ago that turned out pretty cool. The front end, tonestack and the output stage are all borrowed from the Big Muff, but the two Muff gainstages is replaced with a discrete op amp (by Joe Davission) modified with a odd feedback transistor clipping configuration.
In the soundclip the gain is maxed, tone at noon and volume at about 9 o clock.
I got the name from one of my favourite movies. :)

Hello.

"but the two Muff gainstages is replaced with a discrete op amp".

Didn't see any opamp on the schematic/layout.

Hi,

I made it. Nice idea but I have to small fuzz sound. I change R4 to 330 ohm and it is better.

Thanks for big job.
