How to Wire a Series/Parallel Pickup Switch into a Guitar

Upgrading your guitar with a series/parallel pickup switch can be a fantastic way to add more tonal options and versatility to your playing. In this article, we’ll walk you through the process of wiring a series/parallel pickup switch into your guitar, step by step.

What is a Series/Parallel Pickup Switch?

A series/parallel pickup switch is a type of pickup switch that allows you to combine the tone of your pickups in two different ways: in series and in parallel. In series, the pickups are connected in a single circuit, which creates a more aggressive, articulate tone. In parallel, the pickups are connected in separate circuits, which creates a more balanced, blended tone.

Tools and Materials Needed

• Series/parallel pickup switch (available at most music stores or online)
• Wiring diagram or instructions for your specific guitar model
• Wire strippers
• Wire cutters
• Soldering iron and solder
• Electrical tape or wire nuts
• Optional: tone capacitor (if you want to add a tone control)

Step-by-Step Instructions

1. Identify the Pickup Wires: Locate the pickup wires on your guitar. You should have three wires per pickup: one for the hot output, one for the ground, and one for the shield (if your pickups have a shield).
2. Disconnect the Pickup Wires: Disconnect the pickup wires from the output jack and any other electronics on your guitar. You may need to use wire cutters or wire strippers to release the wires from their connectors.
3. Connect the Pickup Wires to the Series/Parallel Switch: Connect the pickup wires to the series/parallel switch, following the manufacturer’s instructions. Typically, you’ll connect the hot output wires to the "in" terminals on the switch, and the ground wires to the "out" terminals.
4. Add the Tone Control (Optional): If you want to add a tone control to your series/parallel switch, connect the tone capacitor to the switch. The tone capacitor will help to filter out high frequencies and add warmth to your tone.
5. Connect the Switch to the Output Jack: Connect the output of the series/parallel switch to the output jack on your guitar. Make sure to connect the correct wires (hot and ground) to the output jack.
6. Solder the Connections: Use a soldering iron and solder to connect the wires to the switch, output jack, and any other components (such as the tone capacitor). Make sure the connections are secure and won’t come loose over time.
7. Test the Switch: Plug in your guitar and test the series/parallel switch. Make sure the switch is working correctly and that the tone is adjusting as expected.
8. Add Electrical Tape or Wire Nuts (Optional): If you’re concerned about the wires coming loose over time, you can add electrical tape or wire nuts to secure them.

Tips and Troubleshooting

• Make sure to follow the manufacturer’s instructions for wiring the series/parallel switch. Each switch may have slightly different wiring requirements.
• If you’re not comfortable soldering, consider taking your guitar to a professional luthier or guitar tech.
• If the switch is not working correctly, check the wiring diagram to ensure that the connections are correct. Also, try cleaning the switch contacts to ensure that they’re free of corrosion.
• When adjusting the tone control (if you added one), start with the tone set to the "bright" position and gradually turn it down to achieve the desired tone.

Conclusion

Wiring a series/parallel pickup switch into your guitar can be a bit challenging, but with the right tools and a bit of patience, you can achieve a unique and versatile tone. Remember to follow the manufacturer’s instructions, and don’t be afraid to ask for help if you’re unsure about any part of the process. Happy upgrading!
