You can change and improve the tone of your guitar by updating the pickups. RMC is a brand of pickups based out of Berkeley, California that covers a variety of pickup styles. You can choose your type of pickup based on the type of music that you play. For example, a bass guitar will have a specific pickup for a particular sound. Though professional installation is offered by many music stores and professionals, this can be a do-it-yourself job.
Remove the back cover and the pick guard of your guitar. Take note of the pickup output and ground wiring configuration. You will need to remember this later for installing the new pickup.
Disconnect the volume pot and ground. Use a soldering iron to melt the connections. Once melted, they can be released from the body of the guitar. Remember where you have removed these parts from for reinstallation.
Remove the pickup from the body of the guitar. Do this by unscrewing its connections and gently pulling its wires with it.
Install the wires of the new pickup. Run them to the electronics compartment through the body cavity. The white wire is for output. The braided wire is the ground. The red wire will be connected to the 9-volt battery circuit. However, not all models have the red wire and battery.
Connect the white output wire and the braided ground wire to the output and ground connections from which you removed the old wires. If you have a red wire and 9-volt circuit, connect these two parts. Solder all connections.
Install the replacement RMC pickup. Do this by screwing it into the place from which you removed the old pickup.
Reconnect the back cover and pick guard in the locations from which you removed them.
Draw a diagram as you disassemble the guitar. This will help you record where parts go.
