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. Dimensions: BQC (Mid/Bass/Treble) Equalizer Warranty All EMG Pickups and accessories are warranted for a period of two years.

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.
