Built specifically for EMG pickups, the BQC System works as a complete control system for bass guitars. It incorporates a pre-wired active balance control which allows for loss-free balance between two pickups, a BQC Control 3-band equalizer featuring dual-pole filters for broadband equalization, and a master volume. Both the bass and treble are on a concentric pot as well as the mid-control. The balance control and EQ controls all come with convenient center detents to let you know when no equalization is in effect.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.

Great replacement

I have a Spector Euro 4LX FM and the Aguilar OBP-1 pre amp in the bass was terrible for the woods used, tried to buy one of these in Europe, the price was stupid.Took a little while to get it, was a bit fiddley to install (Had to solder pick up wires on) but the snap connectors were a breeze, works very well with the Spector
