ZVex Fuzz Factory - compact layoutVerified
Based on the Z.Vex Fuzz Factory· 24 other boards clone it
From the post
A more compact layout for the Fuzz Factory using radial caps, so I thought I'd add a new post rather than add it to the old layout, to avoid confusion as this one obviously isn't verified yet.
Info about the original:
This is a five-knob fuzz using two new old-stock sixties germanium transistors. The circuit is not modeled after any classic fuzz design, but should have been around when Leary was still lucid. Although the five knobs are named for the parameters over which they seem to have the most control, please don't hold me to it. They are controls for various operating levels and biases, and basically shape you a personalized fuzz.
Schematic
This is a board layout, a drawing of where each part goes, and the post may link the schematic it was drawn from. Open the layout at Tagboard Effects. No KiCad fragment has been drawn for this circuit yet.
