User Reviews of the Boss Parametric Equalizer PQ-4
Submitted by K. from Sealy, TX (532 points) on Mar 16, 2002
Great pedal for shaping the tonality of your signal, much better range than a graphic EQ. There are individual level controls for each frequency plus they are individually adjustable within specific ranges - low -18 to +18, mid 100 to 1.6k, and high 500 to 8k.
Good Points: Wide variety of tonal possibilities
Bad Points: Very sensitive, easy to lose settings, concentric knobs which control frequency range can be a pain when making quick adjustments
