The JHS Calhoun is a signature pedal built by JHS to the specs of Heartbreaker and noted dog lover, Mike Campbell. This pedal packs a double helping of drive and fuzz with EQ controls for each. Both effects can be run in series or individually, and the center toggle allows you to switch the order when both are engaged. With additional controls over Bias, Volume and Fuzz, the Mike Campbell Calhoun is a versatile tone-sculpting machine that brings a massive array of drive flavor to your rig.
