Created this pedal today.
Found an old Volume pedal at a guitar shop today. $15.
Found a 10k pot at Radio Shack along with a stereo 20' cord and strain relief.
Printed a label.
Voila!
It's loud and clear!
1/3 volume is about all I can stand, and that's going through 8 ohms.
Very clean until the fuzz is turned on, and it does its job very well.
I'm going to hate to sell it.
