Will this pedal circuit work?

[the hirsh]

Basically all I want to do is have a pedal with a guitar volume pot in it so that I can drive my single channel amp hard and then get cleans by having a volume pot in a pedal, like rolling down the volume on the guitar. Will this circuit do what I want?

This circuit design would be helpful too!
