Iron Man Amp Settings
Iron Man's opening riff is the sound of heavy metal being born. Tony Iommi's thick, dark, detuned tone through a Laney Supergroup — played with prosthetic fingertips — created a new template for heavy guitar that influenced generations of metal players.
What Makes This Tone Iconic
Iommi essentially invented heavy metal tone. After losing his fingertips in a factory accident, he tuned down, used lighter strings, and developed a playing style that favored power and simplicity over speed. The Laney Supergroup amp's dark, thick voicing combined with his detuned SG creates a massive, doomy tone. Iron Man's riff is slow, simple, and crushingly heavy — proof that tone and attitude matter more than technique.
