The Improbability Drive is a knob-tweaker's dream–equal parts, overdrive, fuzz, and science experiement, and gets its name from Hitchhiker's Guide to the Galaxy. This one was a bit of a challenge (I even had to use a jumper. Gah!). B3ar over on FSB requested a layout with onboard pots and switches. Couldn't get the switches to fit, but they're only SPSTs so wiring those shouldn't be too much of a hardship. Onboard pots are mounted from the solder-side using right angle PCB mount pots. Should all fit in a 1590B.
The diode is there for polarity protection. It's not necessary to the sound of the circuit, but is a good thing to include in case the wrong kind of power supply (like a center positive supply instead of the the standard center negative) is plugged into the pedal.
