TB-4 Wiring help

[Ivo Kalis]

One capacitor is correct for the wiring diagram.

I agree that the kit should have two A500k for volume and one B500k pot for tone. It may be worth checking with a multimeter what the mid turn resistance is on the B pot between the middle tag and one of the end ones. If it is linear, then you should be reading around 250k, if log/audio, either nearer 90k or 410k (depending on the end tag chosen). If B is linear, then email Pit Bull and ask them to send out another A pot. If log, then the A and B designations on the kit pots are simply swapped (annoying but it could happen), so use the Bs for volume and the A for tone.

The pickups supplied have 4-conductor wiring, not the 1+ screen shown in the wiring diagram. Unless you feel like wiring the pickup coils in parallel rather than series for a brighter tone, or adding a coil split switch for single coil sounds, you use:
Black - signal hot
Green+screen - signal ground
Red+White - wires that connect the two pickup coils together internally. Leave unconnected and tape up the bare ends to avoid them shorting out. If you want a coil split, then this red/white combo is connected to an extra 2-way switch that can connect the wires to ground.

So if I follow you correctly:
- use the black wire from the neck pickup instead as the blue in the diagram
-green+screen from neck pickup is signal ground on the first potentiometer
-use black wire from the bridge pickup instead of the red on the diagram
-green+screen from bridge pickup as signal ground for second potentiometer
-tape up red/white wires
-Use rest of diagram

But how to make ground with the bridge? there is no internal hole to get there?

Hi Ivo.

Yes, for the wiring. Just to be sure - each red/white wire is taped up separately.

For the ground to the bridge - My kit had a small hole drilled from the bridge post hole closest to the control cavity. In the cavity, this hole was very close to the jack socket hole. Hopefully your kit has this predrilled, but if not, it should not to too hard to drill.

so this is what i thought you described to me. But somehow I only get Static noise from the moment I put in my jack plug.


What am I doing wrong?
