Adding electronics to an acoustic guitar is a great way to amplify your sound, making it easier to perform in larger venues or record your music with better clarity and volume.
Whether you’re a solo performer, in a band, or simply enjoy experimenting with your guitar, installing a pickup or preamp system can significantly improve the sound quality and versatility of your acoustic guitar.
In this guide, I’ll walk you through the steps on how to add electronics to an acoustic guitar, from choosing the right system to the installation process.
Why Add Electronics to an Acoustic Guitar?
Before diving into the installation process, it’s essential to understand why adding electronics to your acoustic guitar might be beneficial. Here are a few reasons:
- Improved Sound Projection: Electronics allow you to amplify your acoustic sound, making it easier to perform in larger spaces or with a band.
- Control Over Tone: With a built-in preamp, you can adjust the tone, volume, and EQ to suit your preferences.
- Recording and Performance Flexibility: Electronics provide a clean signal that’s perfect for recording and allows you to plug directly into amplifiers or sound systems.
- Reduced Feedback: Modern pickups and preamps are designed to minimize feedback, making them ideal for live performances.
Types of Electronics for Acoustic Guitars
Before starting the installation process, it’s important to choose the right electronics for your guitar. Here are the main types of systems available:
- Piezo Pickups
Piezo pickups are the most common and affordable type of pickup for acoustic guitars. They work by sensing the vibrations of the guitar’s top and converting them into an electrical signal.
These pickups are often installed under the saddle and can be used with or without a preamp.
- Magnetic Pickups
Magnetic pickups are more commonly found on electric guitars but can be used on acoustics as well. They sense the vibration of the strings rather than the soundboard.
Magnetic pickups tend to produce a more electric sound and are popular for players who want a mix of acoustic and electric tones.
- Microphone Systems
Microphone systems use small microphones to capture the natural sound of the guitar. These systems are ideal for capturing a more true, uncolored acoustic tone.
They are often paired with a piezo pickup for better performance in live settings.
- Active vs. Passive Systems
Active systems have a built-in preamp and require a power source (usually a 9V battery), while passive systems don’t need power but may require more amplification.
Active systems offer more control over the tone and are typically quieter than passive systems.
Tools and Materials You’ll Need
Before you begin the installation, make sure you have all the tools and materials necessary for the job. Here’s what you’ll need:
Tools Required:
- Soldering Iron and Solder: To connect the wires to the output jack and the electronics.
- Drill with Small Bits: To create holes for the preamp controls and output jack.
- Screwdriver: For installing the pickup or preamp.
- Wire Cutters: To trim wires to the right length.
- Wrench or Pliers: For securing the output jack.
- Tape Measure: To measure placement of the electronics components.
Materials:
- Pickup and Preamp System: Choose the system that best suits your style and needs.
- Output Jack: Often comes with the pickup system, used to plug the guitar into an amplifier or PA system.
- Battery Clip (for active systems): To power the preamp in active systems.
Step 1: Choose the Right Pickup System for Your Guitar
The first step in adding electronics to your acoustic guitar is selecting the right pickup system. Depending on your musical style, budget, and tonal preferences, you can choose from the systems mentioned above.
Some pickup systems come with everything you need, while others may require additional components, such as a preamp or microphone.
When choosing a system, consider:
- Your budget: Higher-end systems can provide better tone and durability but may be more expensive.
- Tone preference: Do you want a natural acoustic sound, or are you looking for a more electric-style tone?
- Installation complexity: Some systems, like those with preamps, may require more invasive installation (drilling, wiring).
Step 2: Prepare Your Acoustic Guitar
Once you have your electronics, it’s time to prepare your guitar for installation. Here’s how:
- Loosen the Strings
Start by loosening the strings so they are out of the way during installation. You don’t need to remove them entirely unless you want to replace the strings while installing the electronics. - Clean the Guitar
Make sure the area where you’ll be installing the pickup and preamp is clean and free of debris. This ensures that the electronics sit properly and don’t get damaged during installation. - Mark the Installation Points
Use a pencil or tape to mark the locations where the electronics will go. Typically, the piezo pickup is placed under the saddle, and the preamp or controls are installed on the side or inside the guitar body.
Step 3: Install the Pickup
- Remove the Saddle
If your system uses a piezo pickup under the saddle, you will need to carefully remove the saddle. Gently lift it out and make sure the area beneath it is clean. - Place the Piezo Pickup
If you’re using a piezo pickup, place the sensor element underneath the saddle. Make sure the pickup is positioned properly to detect vibrations from the guitar’s top.
Some pickups may have a small adhesive or foam to secure them in place, but make sure it doesn’t interfere with the saddle’s seating.
- Reinstall the Saddle
Once the pickup is properly placed, reinstall the saddle and check that it sits correctly. Ensure that the pickup is not compressed or wedged in a way that could affect the guitar’s intonation.
Step 4: Install the Preamp and Controls
If your system includes a preamp, this is where the majority of the work comes in. Follow these steps to install the preamp:
- Drill Holes for Controls
Use a small drill bit to carefully drill holes for the preamp controls (volume, tone, etc.). These are typically installed on the side of the guitar near the lower bout.
Take your time and double-check your measurements to ensure the holes are placed correctly.
- Install the Preamp
Place the preamp inside the guitar body, ensuring that the controls align with the holes you’ve drilled. Use screws to secure the preamp in place. - Wiring
Connect the wires from the pickup to the preamp. Depending on your system, you may need to solder the connections, so make sure you have a steady hand and a reliable soldering iron. Be sure to follow the instructions provided with your pickup system for wiring details.
Step 5: Install the Output Jack
- Drill a Hole for the Output Jack
If your system requires an output jack, you’ll need to drill a small hole on the side of your guitar to mount it. This hole is typically located on the lower bout of the guitar. - Install the Output Jack
Insert the output jack into the hole and secure it with a wrench or pliers. Then, connect the wire from the preamp to the jack, ensuring a solid and secure connection.
Step 6: Test the Electronics
Once everything is installed, it’s time to test the electronics:
- Reconnect the Strings
Tune the guitar back up and check the action and intonation to ensure everything is in order. - Plug into an Amplifier
Plug your guitar into an amplifier or PA system and test the sound. Adjust the tone and volume controls to your liking, and make sure there are no unwanted buzzing or feedback issues.
Step 7: Final Adjustments
Once you’ve tested the electronics, you may need to make final adjustments. If you’re using an active system, check the battery placement and ensure that the system is powered on. For passive systems, make sure the output jack is securely connected.
