BLACK SABBATH

Effect: Treble Booster

Prior to Black Sabbath, Tony Iommi and Bill Ward had been playing together in Mythology, which is when Iommi first got his hands on a Dallas Arbiter Rangemaster treble booster that was later modified by a friend’s brother. “I don’t know what he did to it, but it was really good!” he told TG in 2010.
