In the words of JHS Pedals:

At its core, the Artificial Blonde is a very simplistic approach to Madisons signature sound: a never off, always on, slightly 3D pitch vibrato sound. The secondary footswitch switches between the two speed/depth preset sections. Its a true pitch vibrato modulation pedal with two easy-to-access modes for live use. Simply put, this is Madison Cunningham in a box: just add a clean Fender-style amp and tune real low!
