This is the writeup on this unit from the 1982 MXR catalog

"You will inevitably be playing music in places with less than optimum environments for performance. Small clubs, gymnasiums, or anywhere outside your regular practice room require you to have some sort of control over the environment, so you can sound the way you want. The devices shown on this page are intended to give you that control, whether you need to boost your sound, roll off noise, or change the timbre of your instrument in response to the acoustic characteristicts of the room.

Note: We have listed below the primary features of the Six and Ten Band Graphic Equalizers. A more detailed explanation of the equalization process appears later in the catalog."

Six Band Graphic EQ

"The Six Band Graphic Equalizer is designed for modification of tonal response over a frequency range of 100Hz to 3.2 kHz. It features six bands (each spaced one octave apart) with boost and cut of 18dB on each band. Its response range makes it the perfect unit for the equalization of electric and acoustic guitar, bass and brass. The Six Band Graphic Equalizer is battery operated, with a battery life of up to one year, in normal use.=
