Unpleasant high-order harmonics are eliminated by a low-pass filter leaving only a full, rich, distorted sound. When the Clipper is switched on, the instrument's volume control adjusts the amount of distortion. The output level of the distorted signal is adjusted internally to balance the fuzz loudness with the normal output of any instrument. The Blue Clipper produces a superstinging fuzz effect when combined with a Green Ringer. Input Impedance is 110 k Ohms. Output Impedance is 3 k Ohms, and the Signal-to-Noise ratio is 82db.
