We're not really sure on the history of Engl amplifiers apart from their break in 1984 at a Convention where one of their amplifiers became the flagship. A German company who's amps have come to us a few times for breaking down, but nothing less than other brands. We're talking the daily wear and tear breakdowns. We like to repair Engl amps, like their history information is a little limited however their amps make sense to us and we're able to repair all that have faced our bench!
