AER is to acoustic amplifiers what Marshall is to electric guitar amplifiers. Most fingerpickers who claim to be something trust in the precious amplifiers from Recklinghausen Germany. Most well-known acoustic festivals even trust exclusively in the fantastic sound of AER acoustic guitar amplifier. The amplifier range of AER offers a solution for everything. The range starts with the small AER Alpha with 40 watts oacked in a small cube. The sound it produces is nearly unreal in comparison to it´s bigger brother, the AER Compact 60II fulfilling all wishes regarding sound, power, effects and inputs (available as a battery powered version). And the range reaches all the way up to the AER Acousticcube III amplifier with a total of 120 watts, 100 effect presets and a very intelligent input routing.
