With the Dan Armstrong Original Blue Clipper, unpleasant high-order harmonics are eliminated by a low-pass filter, which leaves a full, rich, distorted sound. When the Original Blue 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 Clipper effects module produces a super-stinging fuzz effect when combined with the Dan Armstrong Green Ringer. Input Impedance is 110 k Ohms. Output Impedance is 3 k Ohms, and the Signal-to-Noise ratio is 82db.
