Distortion in music is everywhere—unavoidable perhaps. The majority of distortion circuits usually amplify a signal, then feed it into a diode clipping stage and call it a day. But, there are non-linearities within diodes that can be exploited. This circuit does something different—rather than amplifying, then passing through the diode clipper stage, this circuit passes a signal through a diode clipper, then through a two-stages of transistor amplifiers.
The first amplifier stage will amplify a signal enough to overdrive the second transistor amp stage. When this happens—to use the most technical terms—it will sound pretty friggin' sweet.

The circuit is going pretty well so far. The problem I'm having is with the transistor amplifiers.
When I first attempted the first stage of the amplifier, I ended up producing a rather nice and smoky aroma—like there was a component barbeque somewhere. I ended up frying one of the coupling capacitors, so that was great.
I've decided to go with a common-emitter amp because, well, who doesn't use those?
Anywho, I need to get back to finishing the design for the first stage. I'm planning on having variable gain for it and the second stage, but I think I will incorporate potentiometers into them later.
