An excellent choice for solo performers or duos.

The Blackstar Sonnet 120-watt combo amp is an excellent solution if you want versatility. Sonnet is one of the most feature-rich and best acoustic guitar amps on this list, boasting things like 3-b EQs, pad polarity reverse, and an anti-feedback system.

The Blackstar Sonnet also has two channels, a separate phantom power option for each channel, necessary effects, and a rich set of connection interfaces. You have two sets of XLR D.I. outputs for the two channels that Sonnet supports, and you’ve also got MP3/line-in, USB audio, as well as MIX D.I. output.

The Sonnet acoustic combo features a 1×8” + tweeter setup as well to enhance the highs of your compositions. Each channel can also be adjusted with effects independently. The sound produced by the Sonnet acoustic amplifier is very clean as well – as expected for the price.

One thing we dislike about Sonnet is that reaching for the controls isn’t as easy as with some other models on this list. It looks cleaner from the front though thanks to the control panel’s location, which may matter to some musician.

Difference between an acoustic amp and a regular amp

The main difference between an acoustic and a regular electric guitar amp lies in how they process sound. Typically, electric guitar amplifiers enhance the tonal spectrum of electric guitars. In contrast, good acoustic amps usually only amplify the sound without altering its tone too much. Aside from that, electric amps usually have a stronger mid-range, while acoustic amplifiers typically feature tweeters for better high-end frequencies.

Additionally, acoustic guitar amplifiers very often have a mic input for vocals, as well as to allow you to hook an acoustic guitar without piezo pickups to the amp. Electric amplifiers typically don’t have mic inputs.

With that said, many acoustic guitar amps today have onboard effects anyway, so they may also be used to enhance the sound of an acoustic guitar. The boundaries between acoustic and electric amps these days are fairly blurred, and you may use any type of amp as long as it has the necessary inputs and satisfies your needs.

What Guitar Amp Should A Beginner Choose? 

best amp for acoustic guitar

Choosing the right amp is a bit difficult if you’re a beginner, there are so many models and you’re not sure which amplification system will suit you. There are a couple of things you should keep in mind before buying one.

  • Bigger Isn’t Better: The bigger the better? Nope, if you’re playing at home you won’t need anything bigger than a 100-watt amp. Even 50 or less will do if you are not a professional. Amplifiers of 100 watts or more are for playing outdoor concerts and gigs. Also, keep in mind the portability issue.
  • Choose An Amp With Simple Controls: Using an amp can be complicated for beginners, so, choosing an amplifying system with simple controls can be helpful. Starting off with an amplifier that has one channel and some features like gain and reverb is a good choice.

How To Get The Best Out Of Your Amp?

Guitar amps have different tones and each one of them is unique. But how do you get your amp to make that sweet acoustic tone that you’ve always wanted to hear?  Here are some tips on how to get the perfect tone.

Location Of The Amp

Put your amplifier against the wall and jam for a bit then, move it and put it on a table. As soon as you start playing, you’ll notice that the tone has changed! Moving your guitar amp will result in different tones. So if you don’t like your amp’s tone you can simply change its position. You can also look for an amplifier stand if you like the tone of the amp when it’s raised off the floor.

Cables

The cables you’re using have a very big effect on the amp’s tone. Using low-quality cables will give you a weak and distorted tone.

Strings

So your amp’s tone has become dim? Check your strings. Cleaning your strings regularly and changing them helps a lot with getting a better tone. So always make sure to change your strings every once in a while.

Features You Should Look For In An Amp

Choosing the right amplifier depends on what you’re going to do with it, some amplifiers are fit for playing gigs, some are for just playing in the practice room and some are best suitable for a recording studio. This is why deciding what you’re going to do with your new amp is essential before getting one.

best acoustic guitar amplifiers

Guitar amps differ in size, power, controls, effects, and number of channels. So to make things easier for you, we’ve made a list of features that you should look for in a best acoustic amp.

1. Power Output

If you’re planning on getting an amplifier for gigs and live performances you should look for a 100-watt amp or more. Amplifiers of less than 100 watts are usually for home use and practice.

2. Channels

Most acoustic amps with 1 channel will make do. But acoustic guitar amps with 2 channels come in handy if you want to plug another guitar/instrument in. you can also plug in a microphone so you can sing while you’re playing. Make sure that each channel has its own controls so you can adjust the volume, reverb, and tone of each channel.

3. Effects

Guitar amplifiers usually come with built-in guitar effects. But, not all of them have the same effects. Some have reverb effect while some have chorus effect, some have both. If you get an amp with many built-in effects, you won’t have to break the bank on effect pedals.

4. Inputs

Acoustic guitar amps typically have various input interfaces – usually 1/4-inch connectors for the guitar itself and an XLR connection for microphones. If your acoustic guitar doesn’t have a piezo pickup, then a microphone input is a must.

For most people, these inputs are more than enough.  Some guitar amplifiers also have 3.5mm ports that allow you to connect a laptop or smartphone to the amp.

Needless to say, your acoustic amp should have all the inputs you need.

5. Feedback Control

Feedback adjustment is an important amenity because the pickup or microphone via which the signal is sent from the guitar to the amp may have feedback. Control on the unwanted response suppresses this phenomenon.

Simple forms of noise control have no adjustability, while more complex systems may allow you to treat specific frequencies. Obviously, the latter drives amp costs up quite a bit.

Do You Need A Tube Or Solid State Amp?

There’s a huge difference between tube and solid-state amps. Tube amps use vacuum tubes to increase the power of guitar signal to the amp while solid-state amps use solid-state electronics like diodes and transistors. Tube amps can be a bit pricey and you have to change the tubes every once in a while.

Each one of those amps has its own tone. Tube amps have a warm tone and the overdrive is smooth while the distortion in solid-state amps can be a bit fizzy and harsh. Tube amps are louder than solid-state, if you have both 20-watt solid and tube amps you’ll see that the 20-watt tube amp is louder.

Most of the acoustic amplifiers are combo hybrid amps. They’re a combination of both solid and tube amps. It uses both vacuum tubes and solid-state electronics.

Can you play an acoustic through a tube amp?

Yes, you can play an acoustic guitar through a tube amp. And despite what some people may suggest, playing an acoustic through a tube amp doesn’t damage the amp. If your tube amp has the right inputs for your acoustic/acoustic-electric guitar, you will be able to use it to amplify the instrument.

With that said, tube amps aren’t the finest choice for acoustic guitars because they don’t deliver as natural sound as acoustic guitar amps. So unless you have no other options, don’t pair an acoustic guitar with a tube amp.

Another issue to consider is that tube amps don’t always have mic inputs. This will matter with acoustic guitars that don’t have piezo pickups.

Frequently Asked Questions

What is an acoustic guitar amp?

An acoustic guitar amp is a type of amplifier designed to help you amplify the sound of an acoustic guitar, which is especially useful for on-stage performances. The purpose and general design of acoustic amps are similar to those of any other amp, but there are some subtle differences that set acoustic amps apart.

Do you need a special amp for acoustic guitars?

You don’t really need a special amp for acoustic guitars, although acoustic amps are distinct from other types of amps. As long as an amp has the right inputs, it will work with an acoustic guitar no matter what. If your guitar doesn’t have a piezo pickup, then the amp should have a mic input so that you can mic up the guitar.

Can I play my electric guitar through an acoustic amp?

You may play an electric guitar through any amplifier, including an acoustic guitar amplifier. You will be able to hook an electric guitar to any amp as long as it has the right inputs. However, the sound may be a bit dry because acoustic guitar amps don’t enhance the mid-range as standard electric amps do. Unless you have a good reason, don’t pair an electric guitar with an acoustic amp – this doesn’t make much sense.

How can I make my acoustic guitar sound better with an amp?

The primary way of making an acoustic guitar sound better with an amp is by adjusting the EQ. Most acoustic amplifiers have an equalizer that you can play around with to squeeze the most out of your guitar.
Another thing you may do is to use effects like reverb and chorus to enhance the acoustic’s sound. Effects don’t work well in some compositions, and not everybody likes to distort the natural sound of their guitars, but this is a viable way of improving sound.
Keep in mind that “better” is subjective and depends entirely on your preferences and musical needs. Educate yourself as to what your amplifier can do and try to play around with its settings to see what works the best for you.
