CONTROLS
VOLUME: Yep.
BIAS: All guitar pedals run on X amount of volts, and in analog pedals, especially transistorized pedals like this one, changing the recommended supply voltage can yield interesting results. This control loads down the voltage from the supplied 9V all the way down to just under 5V. Sonically, this means a "leaner", "smoother" tone that many have compared to video game sounds. Maxing this control out pushes the circuit into a sweet, sputtery texture that evokes slight octave-down tones. In this setting, you have to really dig in while playing to get the most out of it, but in doing so, you shall be handsomely rewarded.
Note: For all you experimentalists out there, the Bias control destabilizes the entire circuit and gives you a sort of "controlled chaos" while playing. However, if your Bias knob is maxed when you plug in the power cable, the pedal will oscillate and provide synth and drone textures until you stabilize it by turning the Gain knob. This will not occur again until power is unplugged and plugged back in with Bias maxed.

GAIN: Many gain controls are tied to a specific semiconductor, and some are wired like volume controls separating one part of the circuit from the rest. This one is wired as the latter, but it separates the guitar from the rest of the circuit. In fact, it's the same as your guitar's volume knob! If you keep this knob maxed, you can control the level of gain with your guitar.
SOUND EXAMPLE
POWER SUPPLY
The Knight School Fuzz accepts a center-negative DC power supply capable of supplying 9 volts and at least .5mA of current (over is fine). Plugging in anything other than this (center-positive, AC, higher voltage) will damage the pedal, maybe even beyond repair. Check your supply and make sure it says all the right stuff. Plugging in the wrong supply will void the warranty and possibly summon a puff of ozone-tinged smoke. Trust me, you’d hate it.
