Hand-built in Germany, AER amps are widely considered to be the hallmark of acoustic amplification.

At AER, electronics still means a great deal of manual work. Measuring and simulation do not suffice. In the end, every single amp is played and checked for sound and function. A small, dedicated and extremely talented team of just over 20 employees are kept busy checking, equipping, documenting, installing, assembling, and checking all over again!
