The Hornby Skewes Zonk Machine

by Brad

Yo. Here’s a layout I did for the Hornby Skewes Zonk Machine. I used the schematic from the Fuzz central website. I put an extra pad for the .47 cap since I couldn’t find a package big enough for the Xicon greenie .47. I also added some GND pads. I usually just connect my footswitch ground to the input jack ground lug but some people might need those extra pads.

I built one up using this layout the other day and I love it. Finding transistors that bias up in it is a total pain though … Be sure to check out R. G. Keen’s good info on biasing the Zonk Machine.

    Gotta make a correction to the schem. Found out later that “R6” is actually 33k not 3k3. Should also mention that it can be important to tune “R8” to control the noise and hiss you can get from this circuit .
