What is the Aguilar OBP-3 Preamp?

The Aguilar OBP-3 is a bass preamp that provides EQ options and boosts the signal of your bass guitar. It has a 3-band EQ with separate controls for bass, midrange, and treble. Additionally, it comes with a switchable midrange frequency control, allowing you to choose between a sweepable midrange and a midrange that is fixed at 400Hz.

Wiring the Aguilar OBP-3 Preamp

Before you begin wiring your preamp, it is important to gather all the necessary tools and materials. You will need a soldering iron, solder, wire cutters/strippers, a Phillips head screwdriver, and the Aguilar OBP-3 preamp itself.

Start by disconnecting your bass guitar’s existing wiring. This may involve removing the control plate or pickguard to access the electronics. Use wire cutters to remove the old wiring, being careful not to damage any of the components.

Next, refer to the Aguilar OBP-3 wiring diagram for instructions on how to connect the preamp. The diagram will show you which wires to connect to which terminals on the preamp. Make sure to follow the diagram carefully, as incorrect wiring can result in damage to the preamp or unintended noise.

Begin by soldering the ground wire to the preamp’s ground terminal. The ground wire is typically black and may be connected to the back of one of the pots on your bass guitar. Once the ground wire is connected, attach the power source wire to the preamp’s power terminal. This wire is typically red and may be connected to the output jack or battery compartment of your bass guitar.

Once the ground and power wires are connected, you can proceed to wire the rest of the preamp. Refer to the diagram for instructions on which wires to connect to which terminals. Use a soldering iron to make connections, being careful not to overheat the components.

After all the wires are connected, double-check your work to make sure everything is properly wired. Turn on your bass guitar and test the preamp to make sure it is functioning correctly. If you encounter any issues, refer back to the wiring diagram and troubleshoot accordingly.
