An attenuation circuit is disclosed that is adapted to be electrically connected between an output stage of a guitar amplifier and a speaker. The attenuation circuit includes a plurality of passive components including a series resistor, a parallel resistor, and an inductance. The series resistor, the parallel resistor, and the inductance are coupled to connect the series resistor in series between the output stage of the guitar amplifier and the speaker, to connect the parallel resistor in series with the inductance, and to connect the series connected parallel resistor and the inductance in parallel with the speaker to present a constant resistive impedance to said output stage and to attenuate power delivered from the output stage to the speaker.
