For decades, AER has set the benchmark for amplifying acoustic instruments, becoming the go-to choice for players who demand natural, dynamic, and true-to-life tone on any stage. Founded in the early ’90s by Udo Rösner, Michael Eisenmann, and Susanne Janz, AER began as a small, passionate team determined to build the world’s best acoustic amp—and after years of relentless experimentation, they nailed it.
Today, under new leadership but with the same core vision, AER continues to refine and innovate, crafting high-quality, powerful, and sustainable amplifiers that faithfully serve musicians around the globe. From intimate coffeehouse sets to world tours, AER amps deliver the clarity, warmth, and reliability that have made them a modern standard.
