Behringer Ultracoustic AT108

The Behringer AT108 is an affordable and compact acoustic amp with 2 channels and a dedicated XLR input. This means that this small amp works like a small PA system where you can amplify both your guitar and microphone. With its 15W power rating, you can't expect much volume from the amp, but it has more than enough for solo practice and for acoustic jams.

As expected, features are streamlined to keep the cost down, but it does have a line input jack for playing along with your favorite tracks, and there's also a headphones out for quiet practice.

Other features include dedicated volume controls for the two inputs, Behringer's "Virtual Tube Circuitry" and a 3-band EQ for basic tone shaping.

Wrapping up the practice and student friendly features of the AT108 is its single 8" speaker, which works nicely for vocals and acoustic guitars, as long as you're not driving the volume too high.

One reviewer aptly put market sentiment into a simple phrase, stating that the Behringer Ultracoustic AT108 is a killer little amp. Most users are impressed with its value for money, especially appreciating its two channel capability which is quite the bonus considering its price.


There are a few users who noted that the amp can sound muddy when pushed hard, but this is to be expected of a small amp.
