The soul of the colored boost is the class A amplifier design and the selectable feedback/bias control. The six presets range from slightly fuzzy to a "in your face" plexi sound. Each preset has its own style of harmonic distortion and clipping, with different effects on a sine wave signal. Soft clipping; hard clipping; clipping on the top, bottom or both sides of a sine wave; and significant changes in frequency happen with each click of feedback/bias switch. Capable of 39dB of boost, the Colored Boost can easily range from gentle sustain to screaming vintage.
