Dr. Boogie

Classic high gain pedal, modeled on a Mesa Boogie amplifier. See the Gaussmarkov site for an excellent layout, schematic and discussion about this pedal. Look at the right hand side of that page to find links to project files including a pdf with both the layout and schematic for easy printing.

For a fuzz it's got a quite high component count. It uses no less than five J201s, twenty one caps, nineteen resistors, six pots, four trimpots and a diode.
