MUSIC AMPLIFIER WITH DISTORTED AND UNDISTORTED OUTPUTS

摘要

An amplifier circuit for providing a combined clean and dirty output signal from an electric guitar. The circuit has a panning pedal that has two potentiometers attached thereto so that movement of the panning pedal results in two continuously varying ranges of resistances being produced by the potentiometers. The output signal of the guitar is provided to the panning pedal and the resistance values of the potentiometers determine the proportion of the guitar output that is to be provided to a clean pre-amp stage (122) and the proportion that is to be provided to a dirty pre-amp stage (120). The clean pre-amp stage amplifies the output signal substantially without distortion and the dirty pre-amp amplifies the signal so as to produce a satured output signal. The outputs of the clean pre-amp stage and the dirty pre-amp stage are then combined to produce an output signal.
