Abstract:

An electric guitar amplifier which utilizes a digital signal processor to produce vacuum-tube-like distortion without certain unwanted audio artifacts created by previous digital realizations of nonlinear, high-gain functions. By virtue of a microprocessor-controlled digital signal processor embodiment, the invention gives the user programmable control over parameters normally associated with state of the art guitar amplifiers (e. g. tone controls, reverb controls, tremolo controls, etc. ), as well as other musically useful parameters which are not normally included among the controls of a guitar amplifier (e. g. selection of preamp type, autovolume, reverberation type, autowah, etc. ).
