K-999 Effects Pedal Kit - MOD® Kits, The Saturator
The Saturator is an overdrive pedal kit that can cover a wide range of gain effects, transitioning smoothly from a massive clean boost to a warm and saturated distortion with the turn of a knob. The saturation is controlled with the "Soak" knob, which dials in the amount of symmetrical soft-clipping applied to the guitar signal. When fully counterclockwise , the signal is unaffected and clean. Rotating the knob clockwise will incrementally increase the soft-clipping, morphing from a clean signal through subtle-to-heavy saturated overdrive sounds and straight into distortion territory. The "Level" knob sets the overall volume of the clean or saturated output. Unity gain is at roughly 8 o'clock. With the "Soak" set to clean, rotating the "Level" knob clockwise will increase the level to upwards of 30dB.

The middle knob is the bias control. This adjusts the pulse width in the initial fuzz stage of the pedal. Set this knob to fit your pickups and playing style. The closer to the center the longer the note will sustain but with that comes more chaotic tracking for the divider. Moving it more clockwise or counterclockwise will give you more predictable note tracking on the divider with less sustain.
