BQS System

EMG BQS System Bass Preamp

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.

    For EMG pickups only.

    All knobs included.

    OPEN BOX ITEM: There is one unit which was opened for the purpose of taking product photos. This preamp has not been installed or used.

    Artists: Edmond Gilmore
  • 3 Band -- 5 Knob:

    Volume -- Balance -- Mid Boost/Mid Frequency Stack -- Treble -- Bass
