The BQS System HZ is a complete control and EQ system for passive bass pickups or EMG HZ pickups. It 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.

All EMG Pickups are built to order. Estimated shipping is between 7-14 business days.

    I have a Dave Ellefson Jackson bass which has HZ EMG pickups but had an aftermarket EQ . I considered buying DC 35 pick ups but I took a gamble with this EQ and payed off . My bass sounds killer now , I can’t believe how it sounds there’s so many different sounds you can get from this preamp . This preamp with HZs work out very nice . So if you have one of the basses that came with the HZs and your thinking about changing pickups don’t do it this thing is great . My bass cuts right through the mix now . Kudos to Alex in sales for helping me with the links to order pickup wires which you will need if you are swapping out an aftermarket preamp.
