This is a selectable onboard passive distortion circuit using clipping diodes wired to ground. All solid-state 'artificial' distortion circuits, no matter how expensive, have something like this at their core. Instead of requiring power, this circuit uses the output of the pickups themselves and therefore should work better with higher output pickups. It uses a 2-pole 4-position rotary switch to select various combinations of diodes for different degrees of distortion, or none. You could also select one of the diode combinations and wire it to a push-pull switch for a single level of distortion, or even wire it to a separate 'volume' control to control the resistance to ground and therefore the amount of distortion. The diodes cost pennies. I have yet to actually try this one, but when I get back to building six-strings, I definitely want to.
