Angus Clark is an expert of all things Tony Iommi, and he has the gear to prove it! The Trans-Siberian Orchestra and Rock of Ages guitarist shows us a couple sweet Iommi tribute SGs as he walks us through Black Sabbath’s discography, breaking down Iommi’s vocabulary, sound, and gear, and how Iommi created some of the most identifiable riffs in all of rock. Angus is plugged in and ready to go, so we get to hear some of the moves in action—including how loose, light gauge strings create the signature Sabbath sound, how it encouraged some parts of Iommi’s lead moves.
