Behringer Ultracoustic ACX450

The Behringer ACX450 is a 45-watt 2 channel combo amp for acoustic guitar. The first channel is for guitar/instrument and the second is for Mic/Line input.

It doesn't have all the features of more expensive amps, there's no phantom power, FX loop, headphone jack, DI or Line outs, but based upon the reviews it does a fairly good job of being a straight-up acoustic amp with a low price.

When you turn the FBQ feedback control on the LEDs on the graphic EQ sliders light up to show you which frequency band is feeding back allowing you to turn down the specific band causing the problem.

Pros

"Great value for the money" or words to that effect are common in positive reviews. Many owners also say it works well for both practice and performing in small venues.

Cons

The lack of additional features did cause several complaints but in my opinion these are unwarranted because this is a budget amp, not a high-end Fishman or AER - you get what you pay for. There were also a few people who said the mid frequencies could be crisper.

Overall

If you're on a beginner or have a limited budget then this is a good choice, in fact it was on our recommended list from July 2016 until November 2017. The reason we're not currently recommending it is because it's ratings have gone down slightly over the last 15 months which other acoustic amps have improved their ratings.
