## Overview

The EMG BQS System is a compact, 5-knob active bass EQ designed for precise tonal control. Featuring separate bass and treble pots, a concentric midrange knob with a sweepable frequency from 100Hz to 1kHz, and compatibility with both active and passive pickups, it empowers bassists to sculpt their sound with professional accuracy. Additional volume knobs enhance versatility, making it a must-have for serious bass players seeking dynamic, customizable EQ performance.

## Description

For EMG pickups only. This system features a pre-wired balance control (blend), master volume, separate bass and treble pots along with the concentric/stacked mid-control. All the EQ controls and balance control feature center detents. This active EQ circuit for bass guitars works by rotating the control clockwise to boost, counterclockwise to cut. There is a center detent for flat response. The mid-range control has a variable frequency knob that allows you to sweep through the mid-frequency range from 100Hz to 1KHz. This selects the frequency to boost or cut.
