By the look of it those are active EMG pickups, no?
If you enlarge the pic, they look like normal 90s/00's black TB-pickups and they read R.B.Rex has a PJ + preamp set with Seymour Duncan, but I don't see any sign of SD.
Irrespective of what many of us think of active circuit basses, an active TBird would actually make sense within the Gibson palette for someone playing music like Herr Brown.You think they already have the name TRexBird protected?
As long as the battery is full, an active bass is a safe bet in a live setting if you know neither the location where or the rig over which you will be playing. You can compensate for most deficiencies and also make a decent stand against a double bass drum.
