AER Alpha Acoustic Guitar Amp

Back to List
  • Description
  • Features

The AER Alpha acoustic guitar amp is perfect for the solo guitarist with its clear, punchy, acoustic tone. AER is known for delivering the true, un-hyped sound of your guitar. With its second XLR combo input, it can also accommodate a mic or second guitar.

40 Watts plus the 8“-twin-cone speaker-system provide plenty of volume in a tiny, lightweight (just over 6 lbs.) cube. To call it inconspicuous would almost be an overstatement. 

3-band EQ and reverb offer plenty of tone control. The back panel also offers DI out, line out, effects loop, tuner out, footswitch input and a headphone out for silent practice.

Why We Like The AER Alpha

In true German fashion, AER offers precision-designed products. Function before form—but what they do, they do exceptionally well. The Alpha delivers great acoustic sound, very true, with exceptional clarity. Any AER amp is an investment, but it will definitely deliver the goods.

The brilliant acoustic guitarist Tommy Emmanuel plays an AER, and we can't think of a higher endorsement.
