As mentioned above the pedal is designed with an output buffer integrated into the circuit. This not only allows the pedal to deal with the low input impedance of most fuzz & overdrive pedals but it also allows you to boost or cut the output of the pedal via the internal volume trimmer. This comes in very handy when adjusting the resonance control as this will boost or cut the gain of the pedal allowing you to adjust it specifically to your needs. The internal sweep trimmer is designed to take the place of the resistor across the inductor of the wah circuit. What this does is dial in the sweep range of the pedal. The greater the resistance the greater the amount of sweep you are able to attain. Dialing this back to zero will result in a loss of wah effect in the pedal. The mid-range control controls the amount of mids within the wah circuit. Dialing this control towards the heal will thin out the sound and dialing it towards the front will thicken it up. This comes set to a stock value of 1.5K which is the norm for most classic wah circuits. The resonance control otherwise known as the growl control adjusts the frequency response or resonance of the pedal. Dialing this towards the hell of the pedal will result in a darker throatier sound. Dialing this control towards the front of the pedal will result in a thinner brighter wah sound. The 6 position DIP switch allows the user to dial in just about any wah sound under the sun. Included is a vintage wah cheat sheet showing the user how to set the wah up to just about every vintage wah tone that a user could ask for. The pedal has no internal battery option due to the space inside of the enclosure. You can use an industry standard 2.1mm center negative power supply to run the pedal. The minimum milliamp recommendation is 100ma.
