About Marshall

https://marshall.com

Marshall was founded in 1962, is a brand from the United Kingdom, its headquarters is located in Bletchley, England. The brand has always been at the forefront of innovation in the audio world, designing and producing not only contemporary products, but also re-creations of the classic models – the guitar amps that defined the sound of rock and British blues in the 1960s and 1980s. For more than half a century, Marshall's mission has been to listen—to listen to the neglected rebels and mavericks. Their goal, past and future, is to make these voices heard.
