Mod Electronics 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 30 dB.
