I have a lot of EMG pickups installed in many of my basses.
What can I say, installing the preamp system with the same pickups is a breeze.
Soundwise is very modern. It also depends on which pickups you use, but the strength and clear sounds this preamp gives is really nice.
Also the tonal variation you can get from the BQC system is wide and flexible.
It's an active system. If you like simple things and passive systems, stay away from this, but if you're on the active side and love variation, this is definitely for you ;)
