Looks like the same controls as the B Quad. Just with 7 individual pots, where the B Quad has 4 of its controls put together onto 2 stacked pots. They still both have 7 different knobs to turn, plus one switch.
So, if it's the same as a B Quad, they are:
Master Vol (for all the pickups - or maybe just the magnetics - I can't remember!)
Bridge Vol
Neck Vol
Piezo Vol
Piezo passive Tone
Treble boost/cut
Bass boost/cut
Switch for Mono/Stereo
My second guess would be the same except for a Blend knob for the magnetic pickups and then a 3-band EQ.
Then there's the 10 trim/pan pots on the back....
I had a B Quad 4 and it was the nicest-playing bass I've ever had in my hands. Now I have the B Quad 5 that used to belong to lofreek (signed by Brian as the first B Quad 5 off the production line) and it has everything the 4 had, plus an extra string!
