EMG BQS System HZ, Control and EQ System for Passive Bass Pickups
EMG BQS System HZ Overview by GAK:
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.

Highly flexible tone shaping. Sweepable mids is perfect. Really transparent when set flat. Solderless installation works really when. Using it with non EMG picks and a bass with a barrel jack, so some soldering was required, but that's what it is. Works really well with the Bartolini pickups in my bass; I assume it'd be fine with any brand of passive pickup. Only grips is that the free knobs are garbage and went go straight in the bin; as people are blatantly going to want their own choice of knobs this seems like gratuitous plastic tat.
