1. A guitar amplifier which comprises:

  • (a) an input terminal;

    (b) an audio output terminal; and

    (c) an audio level controller connected between said input terminal and said audio output including;

    a first attenuation path;

    a second attenuation path having a fixed attenuation; and

    a switch connecting only one of said first or second attenuation paths between said input and said audio output;

    wherein said audio level controller comprises a first variable resistor coupled to said input terminal and having a wiper coupled to said audio output, said first variable resistor being coupled to a source of reference voltage through a second resistor to form said first attenuation path, said switch coupled between the junction of said first and second resistors and said source of reference voltage to provide said second attenuation path.
