The Calhoun is a collaborative signature pedal for legendary guitarist, writer, and producer Mike Campbell. Mike is most known for his role in Tom Petty and The Heartbreakers, but he has worked closely with such artists as Don Henley, Bob Dylan, Stevie Nicks, George Harrison, Jackson Browne, Brian Setzer, Johnny Cash, Fleetwood Mac and The Wallflowers to name a few. He also is a founding member of Mudcrutch and has a side project called the Dirty Knobs. When the opportunity to create his only signature pedal came to us, we were honored, to say the least. Let's go over what the Calhoun has to offer.
The Calhoun is a 2 in 1 overdrive/fuzz pedal that is designed around Mike's specific desires for live and studio performance. Looking at the pedal you will see two footswitches. You will also see a toggle switch in the center near the top. The best way to understand the Calhoun is to picture an imaginary line that separates the two sides; this line goes directly down the center where the toggle switch is located. The left side is the drive portion of the pedal with Volume, Drive, Treble, Bass controls. The Volume control is a master level control allowing you to set the maximum or minimum volume of the pedal. The Drive control adjusts how much dirt/distortion you are allowing in the circuit. The Treble and Bass controls adjust the EQ of the pedal, allowing you to darken and brighten the frequencies as needed. The right side of the pedal is the fuzz portion, with Volume, Fuzz, Bias, and EQ controls. The Volume control acts as the same master volume control as the left side. The Fuzz control adjusts the intensity of the fuzz sound. The Bias control adjusts the voltage to the circuit allowing more powerful tones that bloom with more headroom or weaker and more saturated tones. The EQ control lets you set the range of tone from dark to bright as you wish. The toggle switch mentioned earlier allows you to choose the order of the two effects when stacked (both on at the same time). The effect that the toggle is pointed at is first in series; this lets you stack the effects in whichever way you desire to achieve different textures of stacked tones.
