Manley Massive Passive equalizer

“Equalizer”may be a dirty word in the audiophile dictionary, but this extremely flexible EQ has found its way into many professional recording studios. Featuring two independent mono, four-band passive equalizers in one chassis, the Manley can be quite habit-forming and can turn most audio purists into knob-spinning, frequency-enhancing mastering engineers. We found it to be an “extraordinary device with endless uses.”
