In the words of J. Rockett Audio Designs:

Based on the classic tones of a bearded Texas legend, El Hombre is the ideal overdrive for those feeling the blues or ready to rock all night. Capturing the nuances and touch sensitivity of an amplifier, El Hombre can go from mild to wild with the turn of the gain knob showing its versatility with each guitar plugged into it. From added harmonics to chewy sag El Hombre has it all!
