This circuit is a firm favorite in Nashville and Brian Wampler’s take is everything you would expect it to be – high quality components, a beautiful enclosure, and a glorious tone. If you set the gain low and the bass control up high, you get a wonderful clean boost sound that can rival any Klone circuit, but when you spin the bass down and the gain all the way up, you suddenly find yourself with an awesome transparent overdrive / medium distortion sound with all the crunch you need.

The Color control is more than just a standard tone control and it’s pretty unique to this circuit. Dialling it right or left will either boost or cut the high and low end a little, but the midrange frequencies are left well alone. Combine this with the Bass control and you have a very versatile tone shaping palette with Wampler’s legendary ease of use. Brian has also added a push switch on the side which will control the amount of compression and clipping structure in the circuit for some extra punch.

This pedal can add some serious muscle to your country, some extra grit to your blues, and some soaring boosts to rock – it’s such a flexible drive we are sure you are going to love stacking it with your favorite pedals as much as playing it straight through a clean amp. This pedal really will be the “Belle of the Board” (Bad pun intentional).

CONTROLS

Gain: This controls the total amount of overdrive that is heard. The more you turn it clockwise, the more distorted the sound will become.

Level: Controls the total output volume of the pedal.

Bass: Adjust the level of bass that the pedal outputs / limits.

Color: High- and low-end tone control.

Compression Clipping : Disengaged (Out) for Smooth, Engaged (In) for Asymmetrical Clipping

Power: This pedal was designed around the usage of a 9V or 18V DC power source and is intended to sound its best at 9V. To avoid damage to the pedal, do not exceed 18V DC, do not use center pin positive adapters, and do not use AC power. Use only a 9v-18vdc power source that is intended for guitar pedals.
