Tone This is an active boost/cut control that affects frequencies above the point set by the internal FREQUENCY control (stock 3.2kHz).
Level Controls the overall volume output of the pedal.
Low Cut Cuts bass when turned clockwise. Helps tighten up the low end, which is especially useful with higher-gain settings. Roll-off point range: 33Hz - 1.5kHz
High Cut Cuts highs when turned clockwise. Helps smooth out high-gain fizziness or warm up bright single coils. Roll-off point range: 500Hz - 15kHz
A-L-M This 3-way clipping switch selects between 3 modes - lush saturation using mosfet transistors (M), modern crunch using 5mm red LEDs (L), and asymmetrical overdrive using a one-by-three, silicon & germanium diode arrangement (A).
Internal Controls There are 2 internal controls in the Pale Horse. The upper left trimpot is an IMPEDANCE control, so you can better match the load of your amplifier for the most transparency (Range 200K - 1M). The top right FREQUENCY trimpot selects the cutoff frequency of the active TONE control (Range: 1.2-7.2 kHz).
