Allsound Echotronic delay unit

The Allsound Echotronic is a classic piece of musical gear from the 1970s, specifically an analog tape delay and reverberation unit. It was designed to provide professional echo effects for musicians and studios before the digital era. These units were famously manufactured in West Germany during a time when German engineering in musical electronics was highly regarded.

The brand 'Allsound' was a product of the company founded by Karl Altmann in Munich. While the original company dominated the European market for amplifiers and PA systems in the 60s and 70s, the brand is now considered a vintage collector's item. There is no large multinational corporation owning the brand today as it exists as a legacy name in the boutique vintage audio community. Local distribution was typically handled directly by the Allsound factory or specialized music dealers across Germany.
