Our Bass pickups use the most standard method of wiring. Each pickup has 2 lead wires. The Black Wire will be used as the Ground. The other wire (Red or White depending on the model) will be the Hot Wire.
Here is a common Wiring Diagrams for this style of Pickup.
For Bass pickups with 1 coil, we recommend using Control Pots rated at 500k. For a Brighter response from your tone control, we recommend using a Tone Capacitor rated at .020µF. And for a Darker response, a Capacitor rated closer to .050µF.
