Marshall Stockwell II Portable Bluetooth Speaker

About Marshall

Some of the finest bands and performers in the world, like Jimi Hendrix, Eric Clapton, Slash, Oasis, Muse, Gorillaz, and Bring Me The Horizon, have praised Marshall. We frequently go on tour with performers like Lana Del Rey, Kendrick Lamar, and Justin Timberlake. But without creator and innovator Jim Marshall OBE and his son Terry, none of this would be possible.

Jim was born on July 29, 1923, in London. As a kid, he had tubercular bones, which required hospitalization until he was 13 years old for a significant portion of his early years. He started to tap dancing as his father advised him to strengthen the bones in his legs, and he soon realized he had a gift for music. Then Jim started playing the drums, and by the late 1930s, he was playing semi-pro before starting to instruct.
