Ibanez TMB100 Bass Guitar Wiring Block Diagram Schematic
Notes
The ground lines (black) from the pickups may not be connected to the pickups, they are routed near the pickups. One is probably connected to the bridge.
The ground lines converge at the 1/4" phono jack chassis lead.
The neck pot controls volume and balance. The bridge pot controls bass and treble boost / cut.
