Marshall amps were born out of the desire to create a sound that was POWERFUL. Artists wanted high-quality tone, and they wanted it really loud. Marshall Amplification is a British amp manufacturer, founded by the legendary Jim Marshall in 1962. Over the years, Marshall ‘stacks’ or ‘half stacks’ have been a recognizable backdrop for many great artists including Jimi Hendrix, The Who, Led Zeppelin, AC/DC and more. Marshall amps are known best for sounds fondly termed the classic “Marshall roar” and the unique “Marshall crunch”.
