How to wire an Epiphone Casino

Epiphone is a subsidiary of the Gibson guitar company. Epiphone specialises in making affordable versions of more expensive Gibson guitars, but they also produce some original instruments. The Casino is Epiphone's version of the Gibson ES-330 guitar. It is a hollow-body, thinline electric guitar. Notable musicians including Paul McCartney, John Lennon and Noel Gallagher have performed live using this guitar. An unmodified Casino comes with two Gibson P-90 pickups. The pickup configuration and wiring are very similar to the Gibson ES-330. Both have a volume and tone dial for each pickup, as well as a three-way pickup selector switch.

Obtain a wiring diagram for your guitar. Whether you're replacing or upgrading your pickups, it's essential to follow the wiring diagram. The Casino has the same wiring layout as the Gibson ES-330. If you can't find the diagram for the Casino, follow the diagram for a similar, hollow-body guitar with a pair of P-90 pickups, such as the Gibson ES-335.

Set up a workspace. You need sufficient space to lay the guitar down flat, as well as a power supply for your soldering iron.

Remove the strings and unscrew the pickups. If your guitar has a pick guard, unscrew that too. In order to take the pickups out of the cavity to access the wiring, you need to take the strings off. Remove the Epiphone Casino's pair of P-90 pickups by loosening the single screw on each side of the chrome pickup housing. Gently pull the pickup toward you once unscrewed so you can access the back of it.

Melt the wire connection with your soldering iron and place the pickups to one side. With the pickup disconnected, you can now access half of the wiring.

Remove the knobs to access the remaining portion of the wiring. Since it is a hollow-body guitar, you access the wiring via the front, rather than by removing the back panels as you would on a solid-body guitar. Gently lift the dial from the potentiometer shaft, then unscrew the shaft to access the wiring. You now have access to all of the wiring.

Inspect the wiring for damage. If you spot any loose connections, melt the wire away from the terminal and reattach it. Remove any damaged wire and replace it with new wire. Strip the end of the new wire to expose the metal for a more secure connection. Follow the wiring diagram closely and make sure you replace each wire with the correct type.

Remove any unwanted wire. Pickups come with wire attached. If you are installing new pickups, remove the wire that previously connected your pickups to the potentiometer terminals. If you aren't replacing the pickups, leave this wire intact. To connect a new pair of pickups, slot the wire through the hole in the pickup cavity and thread it through. Pull it out of the other end and solder it to the relevant terminal on the potentiometer. Consult the wiring diagram for the correct wiring configuration.

Screw your pickups back in place and replace the volume dials. Put on a new set of strings and test the guitar.


Remove solder dust with a shaving brush.


If your dials are stubborn, don't yank them; this can damage the potentiometers.
