A True Stimulus Package? With a 5 position switch the Highball is a pedal that goes through the range of what we define as:

Distortion: a circuit that ":shapes" or "distorts the signal with a varying levels of boost.

Overdrive: a circuit which hits the front end of the source harder, and with variable levels of "dirt", into distortion

With a small footprint and controls for Level, Gain, Range and High Cut, it's a real bang for the buck.
