    I picked up a TBC (The Bass Company) JT400. The previous owner had disconnected a couple of wires coming from the preamp so he could disable the active electronics. I've been searching for a schematic on this bass, but haven't had any luck. Does anyone have a schematic on this bass; or if you own one, could you post a picture of the electronics cavity, specifically the green and red (not the red wire from the 9v battery) wires coming from the preamp.
