The Overstayer Saturator is a 100% analog dual channel harmonics and distortion processor, with tone shaping filters and multiple amplifiers for a wide of array of character, from subtle thickening to extreme distortion, balanced to taste with an integrated blend control.

LOW CUT​ - 12 dB (2 pole) sweepable high pass filter with a separate Resonance control. Wide range sweepable from 30 Hz to 4.7KHz, and at high Resonance settings can be driven into oscillation. This is the start of the signal path, and helps define the shape of the distortion and harmonics that follow. The Low Cut circuit is bypass-able with the corresponding button.

RES​ - The resonance control for the high pass filter. Controls the amount of peaking at the cutoff frequency. With high resonant peaks dialed in, the filter can add in huge amounts of low end, while cutting the subs below the set freq. Monstrously huge kick drums, giant dub-style basses, telephone filter fx, self oscillating harmonics are all easily possible with the Saturator filter section.

BOOST​ - Adds a fixed amount of clean gain to raise low level signals and overdrive whatever is next in line. Also engages a pad after the GAIN amp to compensate for the added gain. Functions like a clean boost pedal on the front end of an amplifier.

SATURATION ​- Discrete amp. Controls the amount of non-linear amp saturation and soft clipping. Wide ranging character from subtle harmonic distortion to extreme analog saturation. The saturation section can by bypassed and removed from the audio path, while still allowing use of the filters and Shape 3 circuit.

SATURATION LED​ - Green LED displays when incoming audio passes the saturation threshold, allowing for quick setup into the sweet spot. HIGH CUT​ - Fixed 6dB lowpass filter at 6KHz tames the highs especially with high gain distortion.

GAIN​ - Discrete op amp primarily provides clean gain, but can be clipped and overdriven with boost or high gain settings. SHAPE 3​ - Activates a pre and post emphasis filter to shape the distortion response of the entire unit, and adds 3rd harmonic saturation circuit. This function can be used in conjunction with the “Saturation” circuit, or independently.

BLEND​ - Control to set a balance between the source signal and processed signal.

OUTPUT​ - This sets the final output level, post blend.

IN​ - Master bypass for both channels of the Saturator NT-02A.
