I'm almost sure they're not low impedance.
You might recall that Uwe bought one and put skull knobs on it.
Yeah, tasteful and adult, wasn't it?
The original knobs went on the fretless Mon(k)ey in satin natural finish, you can see them in the background.
The BFG pups sound like TB Plus chromes to me which they probably are, just in black.
The heralded bridge allows close but not perfect intonation, about as good as it would be on a Dean bass, worse than on any Ibanez that is. Too little range although it's positioned slanted. For sheer intonation range it can neither compete with the Holy Immaculate Trinity (HIT bridge) nor the Waffenwick Königstiger bridge.
