EMG BQC System 4-Knob Active Bass Preamp System (875.00)

The BQC System is a complete control system for bass guitars. Active Balance, Master Volume and EQ circuits are included. The EQs allow you separate control over bass, midrange, and treble all via 2 concentric/stacked pots. Rotate 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.
