Parts List (* Not available at Radio Shacks)
2n3904 NPN Transistor
0.1uF Capacitor (Poly-Film)
4.7uF Capacitor (Electrolytic)
3PDT True Bypass Footswitch*
All together, these things cost about $35.
I'm basing my build on this schematic from Home-Wrecker.com:
The circuit is insanely easy to build and can be thrown on a breadboard in less than a minute. Here's what mine looks like on the breadboard.
I also added a 1MΩ resistor for a little voltage divider to get it to work on mine. If you have a problem with your circuit working, just try adding that.
After testing it out on the breadboard for a bit, it was time to solder it up. I decided to use sockets for the caps and transistor, since there are many substitutions for these parts that add their own flair to the circuit.

The original enclosure I was going to use was too small and I could not fit the battery in, so until I can get another one (I'll probably order it next week), I'm using a crappy little plastic box I grabbed at Radio Shack a little while back. Here's the final product all boxed up.
