From Mad Professor:

"Mad Professor Sweet Honey Overdrive (SHOD) is a touch sensitive low gain overdrive pedal. It is designed to overdrive distorted amplifiers and give dynamically controlled light overdrive on clean sounds.

Distortion level can be controlled by pick attack and pickup strength. Harder picking for overdrive and softer for a cleaner tone. With the unique Focus control, you can adjust the feel and dynamics of the pedal as well as overall EQ. Turning Focus CCW you need to play harder to get distortion and the tone is softer, great for jazz and blues. Focus turned CW gives a slight treble boost and earlier distortion great for classic rock."
