BOSS PQ-3B

The Boss PQ-3B is a bass parametric equalizer pedal, listed as the "PQ-3B Bass Parametric EQ". Where a graphic EQ gives you fixed frequency bands to cut and boost, a parametric EQ lets you choose which frequencies you are shaping, which is how a bass player can zero in on one problem area, such as mud around the low mids, without touching the rest of the tone. It sits in Boss's bass line alongside other EQ options like the Boss GEB-7 7-Band Bass EQ and the Boss GE-7B Bass Equalizer.¹

Circuit and power

The PQ-3B is an analog circuit. It runs on 9V DC with center negative polarity and draws 25 mA, so it fits a standard pedalboard power supply without special requirements.¹

Where it fits in Boss's bass range

The PQ-3B sits in Boss's line of pedals aimed at bass players' tone shaping, as a dedicated bass equalizer rather than a drive or modulation effect. RockBoard's PedalPedia describes it as an analog pedal¹, and it runs on 9V DC center-negative power, drawing 25mA¹. That makes it a straightforward addition to a bass rig: a tone-shaping stage alongside whatever drive, dynamics or modulation pedals a player already uses.
