Control Configuration

  1. Volume
  2. Blend
  3. Treble
  4. Bass
  5. Mid/Mid Stack

The BQS System, as a complete control system for your bass guitar, includes Active Balance, Master Volume, and EQ circuits. Unlike the BQC, the BQS System comes with separate bass and treble posts, so you’ll have separate control over bass, midrange, and treble.

The variable frequency knob on the midrange control allows you to select the frequency to boost or cut by sweeping through the mid-frequency range from 100Hz to 1KHz.

The Active Balance control is designed specifically for EMG Active Pickups and allows for a loss-free balance between two pickups. The control comes with convenient center detents to let you know when no equalization is in effect.

I've had this installed for about a week now. I'm using it in conjunction with an EMG P-bass pickup, and an EMG J-Bass pickup.

I've played out with this setup 3 times now, and I'm totally impressed with the new sonic territories I get to explore. More importantly, all the band members I've played with have indicated that this has added a new dimension to the sound of the band.

Totally worth what I paid!
