Instead, it makes the guitar tone amplified faithfully, without modification and no feedback. In brief, the acoustic guitar amp transfers exactly the same sound from your guitar.

In addition, the electric guitar amp has two channels designed, one channel is clean and the other has a gain stage on but the acoustic amp doesn’t. The common reason is that the acoustic guitar amplifier’s one channel has a 1/4“ instrument input jack along with a XLR input available for vocal mic connection. Now, let’s move to the details for choosing the best acoustic guitar amp. 

If you are a professor in playing guitar, maybe these lines are not suitable for you. However, if you just took up playing musical instruments or an amateur in considering amplifiers or even a player who is confused with options, then you can get help from this part.       

When you go to the shop to buy an amplifier, just simply based on two factors that can help you choose your relevant one: your finance- purpose and the device’s features. Here is some specific information.

Amplifier has some following basic characteristics to consider. Take a look before choosing your best acoustic guitar amp.

Amplifier Power

This feature plays a significant role in choosing an acoustic guitar amp. It will become a nightmare if you get the amplifier that is not relevant to your using purpose.

Before, the small amps were usually powered from 20 upto 75 Watts. However, in the present time, there are more and more smaller sizes of new acoustic power. The numbers of Watts can range widely from 5 to under 100 to fit the using situations. 

Home- Self practising: If you just need an amp to enjoy music or practise guitar by yourself, just take it easy to make a choice. All you need is a reasonable price amp with size from 5 to 40 Watts providing you with basic features.

Self Performance In Public: If you are a freelance player and you stand in front of people playing guitar, you will need a higher quality of amp. Particularly, the size should range from 40 to 100 Watts with average feature standards and price. For instance, if you would like to perform in a coffee house or a bar, a 50 to 60 Watts amplifier is enough. However if you enjoy the crowd on the street, you should choose higher quality for your device. In addition, if you also want to sing through the amp, you should carefully adjust the volume and EQ.

The bigger size amplifiers would be powered from 100 upto over 200 Watts, prepared for public performance or professional activities.

Band Performance: When you are a member in a gig and you are going to buy an amplifier for your team, don’t hesitate to choose the one that has mid to high quality powered from 80 to over 150 Watts. Of course the price will be a little high.

Recording: It’s circumstantial to choose an amp for recording. For example, if you are going to make a live setting record, you’d better have a very powerful amplifier. Another case, if you put the mic in front of the amp to transfer the sound to the mixer, you will need a less powered amp.


First to be mentioned is the Feedback Control. It is compulsory for amplifiers that are powered more than 40 Watts to have this kind of feature. The ones that are played under 40 Watts are optional to have.

Most of the acoustic amps provide the users with some kinds of prophylactic measure in order to prevent feedback such as notch filter, sweep and phase. Some kinds of amps are equipped with a frequency sweep control and a notch filter for users to control over the feedback. The other types have on/off buttons known as phase switches.

Built-in Effects

This feature directly affects your produced sound. The common effects included in acoustic amps are: reverb, delay, compression and chorus.

For example, the reverb adds more space to the tone and helps brighten up a dead room also.

Channels and Inputs

These are the features available for more than one guitar to connect. The best recommendation in this situation is choosing the amp that has volume, EQ, effects and so on controlled individually.

Next, if you have unstable performing places, it is necessary to buy an amp that is battery- powered. Moreover, don’t forget to compare the sizes and weights on demand of portability.

Ultimately, Solid State or Tube shape are also important and need to be considered. Particularly, Solid state amps are firm and don’t have much requirements in maintenance. On the contrary, Tube amps that produce the thickest and warmest sound require having their tubes replaced regularly.
