General Operation

The BQC System is an active EQ circuit for bass guitars. Their effects are illustrated in the graphs on the next page. They allow you separate 

control over bass, midrange, and treble. Rotate the controlled clockwise to boost, counterclockwise to cut. There is a center detent for flat 

response. Active or Passive pickups can be used with the BQC and BQSrH Controls.

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. The graphs on page 2 depict the frequency response of the controls.

Battery Power:

If you play the instrument very hard, and are boosting the bass or treble with the BQC, you should consider operating the instrument on +18 

Volts (See “Power Tips” under Accessories/product data sheets at http://www.emgpickups.com). If you play mildly and use a minimum of boost 

the instrument should operate easily on a single 9-Volt battery. Use an Alkaline or Lithium battery for the best battery life and always unplug 

your guitar when you’re not using it.
