Your acoustic sounds great at home, but the second you want to play it through a PA or amp, you need a way to be heard. A pickup is how you bridge that gap.
The trick is that not every pickup installs the same way. A clamp-in soundhole unit asks for no permanent changes, while an under-saddle or built-in system usually means drilling an endpin jack.
This guide explains what an acoustic pickup does and walks through the three main types of guitar pickups you can fit. Then it covers the install for both removable and permanent options.
It helps to know how pickups capture sound before you pick one. Let’s start there.
What an Acoustic Pickup Actually Does
Much like an electric guitar pickup, an acoustic pickup takes the sound of your guitar and converts it into an amplified signal. When you convert and amplify that tone well, you preserve the dynamic, rich, unplugged character where the guitar’s body resonance plays a major role.
Before you focus on installation, it helps to know what these pickups are, why you’d want one, and how they capture sound. Each design uses a different method to pick up vibration and shape character, and that difference is exactly what determines how you mount it.
The Three Types of Acoustic Pickup
There are three major types of acoustic guitar pickup - magnetic (soundhole), piezo (under-saddle), and microphone. Each captures sound in a distinct way, and each installs differently, so picking the right one first will save you time later.
Soundhole (Magnetic) Pickups
A soundhole pickup sits in the soundhole beneath your strings and captures their vibration through magnetic pole pieces, much like an electric guitar pickup. These are the most beginner-friendly option because most clamp directly into the soundhole and require no permanent modification to the instrument.
Under-Saddle Piezo Pickups
Piezo and transducer pickups work by sensing the vibration of a specific part of the instrument, usually placed directly under the saddle on a thin strip or bridge plate. They produce a focused, feedback-resistant signal and deliver the cleanest visual result, since the pickup is hidden inside the guitar.
The trade-off is a more involved install.
Internal Microphone Systems
Microphone-based systems use a small capsule and come in several mounting styles, with internal and external goosenecks being the most common. Microphones are the fussiest of the three styles and can be more vulnerable to feedback if they aren’t set up with care, but they sound excellent and capture the natural percussive sounds you get when you tap the body.
Modern microphone systems have evolved significantly to offer more user-friendly, feedback-resistant features.

Why You Might Need a Pickup
Acoustic guitars are loud and clear on their own, but once you start playing live in larger venues, amplifying the instrument becomes essential. You can set a microphone in front of the soundhole, but it’s far more convenient and reliable to add a pickup and route that signal where you need it.
A pickup also opens the door to effects and direct connections you simply can’t get from a room mic. Once your acoustic produces a clean amplified signal, you can run it into a pedalboard, an amp, or a PA, and shape the tone to suit the room.
How To Add a Pickup to an Acoustic Guitar
How you install a pickup depends largely on how often you plan to use it and how permanent you want the result. Some pickups are clamped in and removed in seconds, while others are mounted inside the body and call for a small amount of drilling.
The sections below break down both routes.
If you want specific gear recommendations, popular choices include the Seymour Duncan Woody, the LR Baggs Anthem, the LR Baggs M1 Active, and the Fishman Rare Earth humbucker - all common starting points for players adding their first acoustic pickup.
Installing a Removable Soundhole Pickup
Many pickups need no permanent modification at all. Soundhole pickups, for example, install by popping the pickup into the soundhole and securing it - usually with foam, rubber, or a simple screw clamp that grips the edges of the soundhole.
The cable runs straight out of the pickup, so there’s no need to drill a hole for an output jack.
From there, you can run the signal to a preamp or pedalboard, or send it directly to an amp or PA. Many small acoustic microphones work the same way: they slide into the center of the soundhole and connect to a belt-pack preamp without any modification to the instrument.
This route is ideal if you play several guitars on stage or want to keep your instrument completely original, since the pickup can be removed in seconds and shared between instruments.
Installing a Permanent Under-Saddle or Built-In System
If you want the cleanest look and the most stable setup, a permanently installed system is the way to go. This typically means mounting the pickup inside the guitar and drilling a small hole for an endpin jack so you can plug the instrument in.
Many of these systems also need a preamp, and installing one may require cutting a small opening in the side of the body where the preamp can be mounted.
Some guitars come with an internal pickup where the preamp is mounted inside the body and the controls sit just inside the soundhole. In that case, the only external modification is the jack itself.
Because this work is precise and permanent, many players have a tech handle the install - and it’s worth understanding how much it costs to install a pickup in an acoustic guitar before you decide.
Working With Preamps and Outputs
A preamp usually offers several settings designed to maximize output depending on the guitar you’re playing, with the right tuning for both nylon and steel strings. Some preamps include a USB output, so you can connect your acoustic to a phone or tablet and use it with a range of guitar effects apps.
Many systems also include an auxiliary input, which lets you blend a microphone signal with the signal from your internal pickup. That blend is what gives many high-end acoustic-electric setups their natural, full sound.
Microphone and soundhole pickups have the added benefit of being easy to remove when you aren’t using them and easy to move between instruments.
Why Adding a Pickup Matters for Your Tone
A pickup is one of the fastest and easiest ways to improve how your guitar sounds amplified. A poor pickup can make even a great acoustic sound lifeless, while a quality pickup can make a modest guitar sound excellent through a PA.
Keep in mind that the amp or PA matters too. The pickup decides what your amp receives, so a good pickup feeding a good amp is what produces a genuinely better amplified tone.
If you add a pickup to your acoustic guitar, expect a real difference in the clarity and body of your plugged-in sound.
Now that you understand acoustic guitar pickups and how to add one, you can take your playing to new heights on stage. Beyond the pickup itself, there are other ways to improve the overall performance of your acoustic electric guitar, from string choice to your signal chain.
Frequently Asked Questions
Can I install an acoustic pickup myself?
Yes, especially with a removable soundhole pickup, which simply clamps into the soundhole with foam, rubber, or a screw mechanism and needs no tools or modification. Under-saddle and built-in systems are more involved because they require drilling an endpin jack and sometimes mounting a preamp, so many players have a guitar tech handle those installs.
Do all acoustic pickups need a preamp?
No. Some pickups, particularly passive soundhole models, can run straight into an amp or PA, while others rely on a preamp to boost and shape the signal.
Microphone systems and many under-saddle pickups perform best with a dedicated preamp that offers settings for both nylon and steel strings.
Will adding a pickup damage my guitar?
A removable soundhole pickup causes no damage at all because it doesn’t require any modification to the instrument. Permanent systems involve drilling a small hole for the output jack and occasionally cutting an opening for a preamp, which is standard, safe work when done correctly - but it’s irreversible, which is why precision matters.
Which acoustic pickup sounds the most natural?
Microphone-based systems generally produce the most natural, true-to-acoustic tone because they capture the full body resonance and percussive detail of the instrument. The trade-off is that they’re more prone to feedback, which is why many players blend a microphone signal with an under-saddle pickup for the best of both worlds.
Final Thoughts
Adding a pickup is one of the most rewarding upgrades you can make to an acoustic guitar, and the right choice comes down to how you play. If you want flexibility and zero modification, a removable soundhole pickup gets you amplified in minutes.
If you want the cleanest look and a stage-ready setup, a permanently installed under-saddle or built-in system is worth the extra effort.
Whichever route you choose, take time to match the pickup to your playing style and your rig. A pickup is an important element of any amplified acoustic, so understanding how to add one - and how each type captures sound - pays off every time you plug in.
