Criteria used for evaluation

Feedback control

Amplifiers that are designed for acoustic guitars have feedback control because their signal either comes from a mic or pick-up. For this reason, there’s a feedback that needs to be cultured with some feedback control functions. Most of our reviewed amps have feedback control features, except for the mini amps that can’t handle gigs.

Power

If your aim of buying an amp is to practice at home, a 20 to 30 watts power amp is ideal. Your amp’s power should increase when the size of your playing venue increases. If you’re going to play for a coffee house, a 50 watts amp is good. Larger venues require at least a 100 watts amp, especially if you’re playing alongside other musicians.

The higher the amp’s power, the higher, the louder the sound.

In-built effects

An acoustic guitar amp now comes with different in-built effects, but there’s a need for you to identify the ones you need. Purchasing standalone pedals can be stressful and costly when you can have all your effects in a soundbox. For example, the Loop effect is useful for a guitar player to develop rhythms and play Solos. 

Reverb is the most important effect for an acoustic guitar sound. It brightens the guitar tone when you’re playing by creating a robust sound.

Dual-channel

This feature is one of the reasons why most musicians want an amp. The mic input feature could come with an XLR input and a phantom power option. An XLR input is a great addition to an amp; it serves a PA system function, and there’s no need to add a public address system when you’re playing. It is more beneficial and will save you the cost of getting an extra PA system in your set-up.

Quality

One of the important factors to look into when searching for an amp is the quality. Quality has a big influence on the amp’s performance, and it isn’t defined easily. The design and materials of a product will showcase its quality. Solid materials mean the amp is high-quality, which means the amplifier will produce a great sound.

To get the right quality, you have to be detailed about the different amps you have shortlisted. An amplifier that can stand heavy-duty usage will never disappoint. Also, popular brands are usually better than some brands you’ve not heard about. Do not be discouraged by the price whatsoever.

Frequently Asked Question

Amps are mostly used by players who play for an audience, no matter how small or large. If you’re good on an acoustic guitar, you’ll need an amp to play on stage when you have a gig. Purchasing an acoustic guitar to enhance your music would be best for you. 

A hobbyist who only fancies playing at home won’t find it appealing to own an amplifier unless they’re ready to go beyond just playing at home.
