AER has been one of the dominant brands in high-end acoustic guitar amps for several years and the 40-Watt Alpha is their popular entry level amp.

Tommy Emmanuel is one of the most notable artists who uses AER acoustic amps, albeit with their much more expensive Domino 3.

Although you can plug both your guitar and mic into it, it's less useful as a small PA than many other options because it only has 1 channel meaning your effects loop is applied to both inputs. It does however provide 24V phantom power on the XLR input.

A common statement in positive customer reviews is that it has excellent volume for a 40W acoustic amp. It is recommended by both nylon string and steel string guitarists, for both fingerstyle and strumming. The general consensus is that it faithfully reproduces your guitar without unwanted tonal coloration. It is also known to work great with mics and miked instruments.


The only consistent complaint in customer reviews is about the price - AER amps are not cheap. One notable point is that I didn't find many customer reviews recommending it for vocals.


If you want a high-end 40-Watt amp and you have the funds, then this is a great option. If your budget can't quite stretch this far then you'll find excellent alternatives in our recommended list of The Best Acoustic Guitar Amps.
