7 BEST Acoustic Guitar Amp in 2021

Are you tired of playing your acoustic guitar and cannot make it sound good? Would you like an amp that has the latest technology but is simple enough for you to use? Don’t worry. You can get what you need with one of the many best acoustic guitar amps in 2021.

Acoustic guitar amps tend to be different from other amps because they usually require a more specific type of sound. This means that some cannot produce very high frequencies or adapt well to mid-range frequencies.

Acoustic guitar amplifiers are often smaller in size than other types because they do not require as much power to function efficiently. They may also be bulky and hard to move around if built into an amp meant for performance. Most only use 30 watts or less, but this can vary depending on the quality of the amp and how it is made.

Many are also designed to focus on giving you a strong bass rather than creating too many effects. This means that most will work best if you play your guitar over them without any extra instruments plugged in.

Some acoustic guitar amps come with digital effects to help produce different sounds, but these may not be suitable for everyone who needs them because they can break down easily if mishandled.

However, with various acoustic guitar amplifiers available in the market, it can be confusing and intimidating. So, we’ve reviewed and listed down the best acoustic guitar amp available on Amazon and what makes them great.

1. Positive Grid Spark Guitar Amplifier



This is our choice for the overall best acoustic guitar amp for the money.

The Positive Grid Spark Guitar Amplifier Combo is an all-in-one hybrid solution that offers the benefits of digital and analog amps in one package.

The amp has a modeled tube preamp section to emulate classic guitar amplifier sounds, although it has the editing capability of most effect pedals. It also comes with a 10,000 plus tone library for your reference.

It has a built-in acoustic guitar tuner, one of the most accurate ones you can find among guitar amps in this price range, and the pedalboard add-on feature allows you to bring other effects like reverb or distortion.

However, since the preamp section is modeled after tube amps, it lacks some of the warmth and fidelity of actual tube amps, so purists may find this amp lacking for their needs. Also, since this is a more powerful amp, it is heavier than some other amps on the market.

For beginners, this amp offers many features in one package, but for more experienced guitar players, it may not have all the features you are looking for. But if you are looking to practice or play smaller venues, this amplifier will serve your needs just fine. Moreover, this acoustic guitar combo is worth its price.





2. Fishman PRO-LBT-600 Loudbox

The good thing about this model is an excellent sound reproduction, easy setup with all types of guitars, and great distortion. It has a pristine sound with no background noise at all! The volume goes to surprising levels before feedback sets in.

It’s also worth mentioning that it can be used as a studio monitor. Just plug your instruments into its XLR or 1/4″ jack inputs, and you’re good to go!

However, small dimensions may be an issue for some players, especially if you need plenty of volume levels. Also, since it lacks built-in effects for distortion and reverb/delay types, you would have to buy them separately or get another model with these features included (you will spend at least double the money, though).

Overall this amp is a great value regardless of its price. It’s lightweight, compact, and pretty much sounds like a much bigger amp.

Questions and Answers about Acoustic Guitar Amps


What is an acoustic guitar amplifier?


Without a doubt, one of the most common ways that could amplify an electric guitar and a bass guitar has been using an acoustic guitar amplifier. These amplifiers typically receive an analog audio signal from a microphone mounted on the instrument and extract enough high-frequency information to inject it into an audio circuit along with an onboard speaker or two.

An acoustic guitar amplifier is a device that helps explicitly amplify the sound of an acoustic, nylon-stringed guitar. Using this type of amp provides a much fuller-sounding tone with plenty of “depth” and richness which is especially important to acoustics as they often lack clarity due to their light nylon strings. The amps also work well for enhancing the sound quality from other instruments, such as steel-string acoustics, mandolins, and ukuleles.


How does the acoustic guitar amp work?


It is a little bit complicated, but the idea is that the input signal from your instrument goes through a preamp – also called a front-end circuit-. The preamp does three things: it boosts the level of the signal, it changes the tone of the guitar to make it richer, which enhances its sound under amplification, and lastly, it reduces feedback.

The signal then goes into a power amp which is essentially the guts of any other amplifier – this amplifies your instrument up to line levels which can then be plugged into any mixer or speaker.

You may not realize, but that chunk of metal in the front-end circuit is a coil (or series of coils) called an inductor. This is quite powerful and affects the input frequency coming from your guitar before it even gets to the preamp!

The wire wraps around a piece of iron or ferrite (magnetic material), and this gives rise to something magnetic coupling (inductance), which is a function of the size and number of wire wraps. It works like a filter or an EQ, shaping the signal before it even gets to the preamp stage.



Do acoustic guitars need amplifiers?


Acoustic guitars are often played without amplifiers. However, some people may use an acoustic guitar amp for a variety of reasons.

The player’s perspective matters because amplification is all about making the guitar sound louder, and what someone can hear without any external help typically varies depending on the person. Amplification may be helpful to compensate for such differences in hearing. But different people experience loss of sound due to disadvantageous positions or background noise differently. So it’s often viewed as a band-aid solution by some players.

A better option would be to find an instrument that a person will enjoy playing if they’re forced to amplify it – which might involve a more “loud” instrument like an electric guitar or mandolin with their higher frequency resonance.



How to choose an acoustic guitar amplifier?


The task is to find an amplifier that will cover the sounds of the guitar but not distort the signal. This means finding one with just enough power without too much distortion at low volumes. At higher volumes, it should still be loud enough but cut through the mix more easily.

Generally speaking, all amps are designed to provide high-quality audio output up to their maximum frequencies. So if you need something for lower frequencies than what’s provided by your amplifier (e.g., for a bass), there’s no use buying it even though it would otherwise fit your bill perfectly.

And on this note: Since most acoustic guitars have a more comprehensive frequency range than basses, they benefit from an amp that offers more rather than less of its max frequency.

Another factor that can be critical for some is the size of the speakers. While more prominent speakers usually have a more bass sound, this isn’t always the case. A smaller speaker can provide just as much bass; it will only lack in volume. And, contrary to popular belief, less volume does not imply less power! In terms of wattage, bigger does not always equal better.




Some Final Words


In light of the above information about the best acoustic guitar amps, it’s safe to say that amps don’t always have to be expensive! But, as always, it is crucial to remember that amps are a matter of personal preference. Whether you favor the type of amp or its features is up to you.

It’s worth noting that some musicians still think an amplifier is nothing more, but a tool to make their sound louder and more precise. However, overwhelming your budget might be. As a result, it’s vital to consider your preferences and your music style and techniques before deciding which type of guitar amp will suit you best.
