Iron Man by Black Sabbath — Amp Settings & Guitar Tone

Reference tone dialed on a Squier Classic Vibe Stratocaster into a Fender Mustang LT25. Settings below are cited from real sources; open the page in a browser for the interactive version, or get this tone dialed for your exact gear.

To recreate the iconic tone of 'Iron Man', we'll use the Squier Classic Vibe Stratocaster '60s and the Fender Mustang LT25. The Strat's single-coil pickups will stand in for the P90s, and the Mustang's modeling capabilities will help us achieve the saturated tube crunch with a slight fuzziness. We'll start with the '04 CLASSIC ROCK' preset, which provides a solid foundation for the mid-forward, heavy metal sound.

What Black Sabbath actually used

Black Sabbath recorded 'Iron Man' during the 'Paranoid' sessions in June 1970. Tony Iommi's setup included a 1965 Gibson SG Special with custom-wound pickups, a Dallas Arbiter Rangemaster Treble Booster, and a Laney Supergroup 100-watt amplifier. The distinctive 'Iron Man' voice effect was achieved using tape varispeed techniques in the studio.
