EMG BQC Control Active EQ Circuit for All Bass Pickup Types

The EMG BQC Control is an amazing active EQ circuit designed for all bass guitars. It gives you separate control over bass, midrange, and treble through 2 concentric/stacked pots. Just rotate the control clockwise to boost and counterclockwise to cut. There's a center detent for a flat response. The mid - range control features a variable frequency knob that lets you sweep from 100Hz to 1KHz, allowing you to choose the frequency to boost or cut. This versatile circuit works with both active and passive pickups, offering great flexibility for bass players.

Using the EMG BQC Control is easy. First, identify the concentric/stacked pots. To adjust the bass, midrange, or treble, simply rotate the control. Clockwise rotation boosts the sound, while counter - clockwise cuts it. When you want a flat response, use the center detent. For the mid - range, turn the variable frequency knob to select the frequency you want to boost or cut between 100Hz and 1KHz. As for maintenance, keep the circuit clean and free from dust. Avoid exposing it to extreme temperatures or humidity. If you notice any issues, check the connections to the pickups. This circuit works with both active and passive pickups, so you don't have to worry about compatibility when using different types of pickups on your bass guitar.
