"Although he started out on acoustic, it was with Muddy’s transition onto the electric that captivated the music world, with the hulking bluesman using a slide alongside open G tuning on many of his greatest tracks, including ‘Mannish Boy’ and ‘Honey Bee’. Waters was also noted for his immense vibrato, and was famous for rolling up the volume knob prior to his solos to create eardrum shattering levels of distortion to cut through the mix and write himself into history."
