Acoustic guitars are known for their rich, natural sound. However, when it comes to performing live or recording, capturing that sound through a microphone or external system can sometimes be challenging.
This is where an acoustic guitar pickup comes in. Installing a pickup can greatly enhance your ability to amplify your guitar’s sound and adapt it for different musical settings. In this guide, I’ll walk you through the entire process of installing a pickup in your acoustic guitar.
Understanding Acoustic Guitar Pickups
Before diving into the installation process, it’s essential to understand what a pickup is and why you need one. A pickup is a device that captures the vibrations of the guitar’s strings or body and converts them into an electrical signal, which can then be amplified through speakers.
Types of Acoustic Guitar Pickups
- Piezo Pickups
These are the most common pickups for acoustic guitars. They are usually placed under the saddle of the guitar and capture vibrations from both the strings and the guitar’s body. Piezo pickups are known for their bright, clear sound and are typically used in acoustic-electric guitars. - Magnetic Pickups
While magnetic pickups are more common in electric guitars, some acoustic guitars also use them. These pickups use magnets and coils to sense the vibration of the metal strings. Magnetic pickups offer a warmer, more traditional tone compared to piezo pickups. - Microphone-based Pickups
These pickups use a small microphone to capture the sound of the guitar’s body and the surrounding air. They provide a natural, uncolored sound but can be more susceptible to feedback in live settings.
Why You Should Install a Pickup in Your Acoustic Guitar
Having a pickup installed in your acoustic guitar allows you to plug into an amplifier or PA system, which is crucial for performances in larger venues or recording in a studio. Without a pickup, you’d rely on a microphone to capture the sound, which can be less effective and more difficult to control in noisy environments.
Tools and Materials Needed for Installing a Pickup
Before you begin, gather the necessary tools and materials for a successful installation.
Essential Tools:
- Screwdriver – For unscrewing parts like the endpin or battery compartment.
- Drill – You may need this for drilling a hole for the output jack or mounting hardware.
- Soldering Iron – For connecting wires to the pickup and preamp.
- Measuring Tape or Ruler – To ensure accurate placement of the pickup.
- Wire Cutters/Strippers – To prepare wires for soldering.
Materials Needed:
- Pickup Kit – This includes the pickup, preamp, and necessary wires.
- Adhesive or Double-sided Tape – To secure the pickup.
- Output Jack – If your pickup requires an output jack hole.
Step 1: Preparing the Acoustic Guitar
Before installing the pickup, you’ll need to prepare your guitar for the process.
- Remove the Strings
To avoid damaging the strings during the installation, it’s best to remove them. This also gives you easier access to the guitar’s interior and components. - Set Up Your Workspace
Make sure you have a clean, well-lit area to work in. Lay down a soft cloth or towel to protect your guitar’s finish from scratches and damage. - Mark the Placement of the Pickup
For piezo pickups, the most common placement is underneath the guitar’s saddle. For magnetic pickups, you may need to mount them near the sound hole or bridge. Use a pencil to lightly mark the spots where you’ll place the pickup components.
Step 2: Installing the Pickup
Now, it’s time to install the pickup in your guitar.
- Mount the Pickup
For a piezo pickup, carefully place the pickup under the saddle or bridge, depending on your model. Some piezo pickups come with adhesive to secure them in place. If not, use double-sided tape to attach it to the saddle or bridge plate. Ensure it is aligned properly to avoid affecting the sound quality.
For magnetic pickups, install the pickup near the bridge or sound hole. Secure it according to the manufacturer’s instructions, which typically involves mounting it using screws or adhesive. Magnetic pickups are easier to install on guitars with a larger sound hole.
- Drill Holes (if necessary)
If your pickup setup requires an output jack, you’ll need to drill a small hole near the edge of the guitar’s side. Measure the location carefully to ensure the hole is in the right position for both function and aesthetics. Use a small drill bit to create the hole and be cautious to avoid splintering the wood.
Step 3: Connecting the Pickup to the Guitar’s Electronics
Once the pickup is in place, it’s time to wire everything up.
- Solder the Wires
Using your soldering iron, connect the pickup’s wires to the preamp or output jack. If you’re working with a piezo pickup, you’ll typically need to solder the hot and ground wires to the preamp input. Follow the instructions included with your pickup kit for the correct wiring diagram. - Test the Connections
After soldering the wires, test the connections by plugging the guitar into an amplifier. If everything is correctly wired, you should hear a clear signal from the pickup. If there’s no sound, double-check your wiring and ensure everything is connected properly.
Step 4: Testing the Pickup Installation
Once the installation is complete, it’s time to test the system.
- Test the Sound
Plug the guitar into an amplifier and play a few chords. Listen carefully to ensure that the pickup is producing a clean, accurate sound. You might need to adjust the pickup’s placement to fine-tune the sound quality. - Adjust the Settings
Most acoustic guitar pickups come with a preamp, which allows you to adjust the tone, volume, and sometimes even EQ. Adjust the settings to suit your desired sound. Be sure to check for feedback or distortion, which may indicate that the pickup needs further adjustment.
Tips for Installing a Pickup in an Acoustic Guitar
- Take Your Time: Installing a pickup can be a delicate process, so be patient and meticulous. Rushing may cause you to make mistakes that could affect the sound quality or damage your guitar.
- Test Everything Before Reassembling: Before you put everything back together and restring the guitar, test the pickup to ensure it works. This will save you time if something needs to be fixed.
- Consider a Professional Installation: If you’re unsure about the installation process or want to avoid damaging your guitar, consider hiring a professional luthier to install the pickup.
Common Issues and Solutions
- Buzzing or Distortion
This is often caused by poor wiring or an improperly placed pickup. Check all connections and ensure that the pickup is mounted securely. - Low Output
If the signal is too weak, try adjusting the placement of the pickup or increasing the gain on your amplifier. - Feedback
Feedback is common in live performance situations. Try using a soundhole cover or adjusting the EQ settings to reduce feedback.
FAQs about Installing a Pickup in an Acoustic Guitar
Can I install a pickup myself, or should I go to a professional?
It’s possible to install a pickup yourself if you have the right tools and patience. However, if you’re unsure, it’s always safer to seek professional help.
What type of pickup should I choose for my acoustic guitar?
Choose a pickup based on your sound preferences and performance needs. Piezo pickups are popular for their clarity, while magnetic pickups offer a warmer tone.
Will installing a pickup affect my guitar’s sound?
A properly installed pickup should not affect your guitar’s tone significantly, but improper installation or placement may impact the sound quality.
Conclusion
Installing a pickup in your acoustic guitar can greatly enhance your ability to perform or record with amplification. While the process can seem daunting at first, with the right tools and a careful approach, it’s something you can tackle on your own.
Whether you choose a piezo, magnetic, or microphone-based pickup, following these steps will help you get the job done right.
