How to Pick the Best Acoustic Guitar Preamp (Buying Guide)

After reading our acoustic guitar preamp reviews, you should now learn how to pick the right one. And for that, you’ll have to consider the different factors that make them suitable or not. Here they are:

  • Types of Pickup Compatibility

First off, you need to consider the type of pickup on the preamp. This refers to the way they work, changing the sound accordingly. Here are three kinds of pickup to consider:

Active Piezo Pickup

Also known as “transducer” pickup, it works wonders with acoustic-electric guitars. The focus of this pickup is to shape the tone of the sound.

If the preamp comes with a pedal and active-piezo compatibility, you can reduce the quacking noise that comes out of the piezo.

An active piezo pickup is called that because it has a built-in battery. It usually connects to the preamp separately from the guitar.

Passive Piezo Pickup

In contrast with an active piezo, the passive pickup usually goes directly into the guitar or other instruments. It relies entirely on the preamp to produce proper sound before going into an amplifier.

The main focus is to increase overall impedance while reducing sound. Most preamps are compatible with piezo pickups, delivering high-quality sound.

Magnetic Pickup

Finally, you may also find preamps more compatible with magnetic pickups. That means you can connect it directly into the preamp without problems.

However, these pickups offer more of an electric-guitar sound than an acoustic one – so not all models are compatible.

·        Presentation (DI or Pedal)

Once you’re done finding a preamp compatible with your piezo, you may want to consider what type of preamp you want.

Some of them are DI, and others are pedal-oriented. Even then, you can find models that offer both at once. Here’s how they differ:


A DI is simply a preamp that reinforces the audio signal to make it of higher impedance. This ability usually comes with excellent feedback suppression and tone shaping, adding more functions to the preamp.

Most DI box preamps are usually input-oriented, with tons of XLR connections for the instruments and other devices.


A pedal preamp is a little more practical, meaning it can usually work as a DI box as well but with a few special effects. At the same time, a pedal allows you to mute and add a bypass to the sound if necessary.

Most pedal preamps are excellent to blend with mixer and interface lines. This adds even more sound quality, ensuring the perfect acoustic tone.

·        Feedback Suppression

After considering the pickup and overall design, you’ll want to go directly into the preamp most essential features.

One of these is the feedback suppression. This is an essential function to have because it reduces unwanted feedback, a sound that makes the guitar distort.

The primary type of feedback suppression system is called a notch filter. It is the go-to choice if you want to keep the feedback to a minimum or eliminate it completely. The preamp you go for must have one of these.

·        Effects & EQ.

Another excellent set of features to include in a preamp are the EQ. or equalizer, and extra effects. Some of these effects are reverb, looping, signal boost, and even a tone shaper or tuner. All these features will take your sound to another level.

You may also add special sound effects like compression, saturation control, gain control, and more. They will help you improve the sound of your acoustic guitar exponentially.

·        Controls

Want to enjoy all the effects a preamp may offer? Then be sure it offers easy-to-use controls.

We usually recommend simple dials and a pedal/button you can press with your feet. Switches are also excellent for controlling the preamp, especially for turning some effects on and off as necessary.

·        Channels (XLR Inputs)

Then you can consider the channels or number of inputs available on the preamp.

It is common to find preamps with multiple XLR inputs. That means you can add phantom power, another instrument or mic line, and more.

Other inputs to consider include USB, S/PIDF, FireWire, and even DAW-friendly outputs. Anything that adds up to the practicality of your preamp is an input worth having.

· Construction & Design

Lastly, consider how well-made the whole preamp is. You will find a wide array of designs and builds out there, every one offering a different experience.

For example, some models are made of aluminum. This is an excellent material to consider if you want the preamp to last.

But even if it is sturdy, you’ll want the piece to also be good-looking. So don’t overlook those preamps that come with enticing designs, making it even more pleasant to play your acoustic guitar.

The FAQ of Acoustic Guitar Preamp

Having doubts is normal when you encounter such a level of complex and exciting preamps. That’s why we want to help you get rid of them.

The following section has some of the most popular questions people ask about acoustic guitar preamps. Then, you’ll find all the answers you need below. Take a look:

What is a preamp, and what does it do?

It merely grabs the audio signal coming from a guitar and transforms it into a low-frequency signal the amplifier can handle more easily.

This produces higher-quality sound, less noise, and better consistency, making sure your audio gear can handle the sound smoothly.

Why do I need an acoustic guitar preamp?

Most guitars have a weak sound. It is not enough to reach the amplifier or speakers without causing distortion or sounding awkwardly low.

With an acoustic guitar preamp, you can make it possible for this sound to be amplified, getting rid of any noise or volume problem.

It is important to note that some acoustic guitars with built-in preamp don’t need an exterior one. Similarly, guitars with magnetic pickups work well without one.

What is the difference between an amplifier and a preamp?

A preamp brings a weak guitar signal to line level. The amplifier brings the line-level signal into speaker-level sound. While the preamp makes the signal transformable, the amplifier makes it listenable.

Can I use a preamp without an amplifier?

No, there’s no way you can use a preamp without an amplifier. Either the audio gear won’t catch the sound at all, or the signal will have too much noise and distortion. You’ll need to hook up an amplifier obligatorily.

Do I still need a preamp if I have a mixer or digital interface?

No, most mixers and digital interfaces come with built-in preamp functions like notch filter, effects, and EQ.

But even then, adding a preamp to your system even with a mixer or digital interface can improve the sound exponentially.

Can I use a receiver instead of a guitar preamp?

Similarly to a mixer and digital interface, you can power up a guitar with a receiver with no problems.

However, the sound quality won’t be the same as that of a high-end preamp with an amplifier. A preamp will always sound a lot better.

How long does an acoustic guitar preamp last?

It depends on how much you use it and what type of use it is. For example, someone who uses the preamp once a week will make it last longer than someone who uses it every day.

But overall, an acoustic preamp may last anywhere from 1 year up to 5 or 10 years with little use.

Does an acoustic guitar preamp work with other instruments?

Yes, some preamps are multi-instrument, meaning you can also pair them up with electric guitars and even basses.

Why does a preamp need a battery or power supply?

As an electrical device, it needs to get its power from somewhere. That’s why most of them are either powered by a set of batteries or a power supply.

We usually recommend power supply models as they don’t run out and are more consistent.

What problems could I face when using an acoustic preamp?

These are several problems you may face with a preamp. But we’re going to show you only the main problems and their solutions. Here’s what we mean:

  • Empty batteries (they run out fairly quickly, so we recommend always having spare ones around)
  • Imprecise adjustments (if you aren’t experienced, you may have a problem adjusting the sound of the guitar)
  • Too much feedback (when the notch filter or feedback suppression system of a preamp doesn’t work, it’s likely to cause unwanted quack sounds)
  • No compatibility with the pickup (be sure that the preamp you’re using is compatible with the type of guitar pickup)


Want to boost your guitar sound exponentially? Then you need to consider our best acoustic guitar preamp reviews.

As long as you follow our buying guide and get rid of your doubts with the FAQ section, then you’re ready to pick the best acoustic guitar preamp out there. You won’t be disappointed.
