The Fender American Deluxe Jazz Bass has active electronics that allow you to dramatically change the tone of the bass to fit your style. To utilise these features, a battery must be installed to power the module. You can wire a new battery or add one to the bass by following some simple instructions that involve a bit of soldering. The flexibility this adds to the bass is worth the little effort it requires.

  1. 1

    Remove the battery cover located on the back of the American Deluxe Jazz bass. This will allow you to access the battery compartment and feed the wiring to the correct areas of the bass for proper operation. The American Deluxe Jazz uses a battery to power the EQ module.

  2. 2

    Place the battery snap into the battery compartment for later use. Slide the red wire into the small hole at the top of the compartment and feed the wire into the control cavity.

  3. 3

    Solder the black wire from the battery snap to the left side tab of the output jack. Flip the bass back over to access the front to complete the installation of the battery.

  4. 4

    Unscrew the three screws that hold the EQ/knob plate in place from the front of the bass. Set them aside and make sure you do not lose them. Carefully lift the plate up taking special care to not break any of the wiring and flip the whole assembly upside down so that you can easily access the PC board, which holds the electronics that need to be wired to the battery.

  5. 5

    Solder the red wire from the PC board to the red wire you just fed into the control cavity. This wire will supply power from the battery to the PC board so that you can use the active electronic to change the tone of the pickups.

  6. 6

    Wrap the soldered area with electrical tape or a shrink tube to prevent any shirts from the exposed solder joint. Replace the entire control plate, making sure to screw the three screws in tightly.

  7. 7

    Install a battery into the battery snap in the battery compartment and replace the battery cover with its screws. Plug the bass in to an amplifier or tuner to see if it is receiving power from the battery. The bass will not have an output signal if the battery is not installed properly.
