The Haymaker incorporates three styles of clipping into a single overdrive stompbox. Topmost controls are for volume and drive. Bottom left is "Highs" which acts as a lowpass filter, and bottom right is "Shape" which sets frequency response similiar to a presence control. Inside the Haymaker is a wet/dry blend trimpot. The Haymaker is an incredibly versatile drive box - able to function as a standalone drive or boost, or stackable with any of your favorite drives or fuzz pedals.

This pedal is in very good condition with some scratching on the bottom.
