Tone Profile
Tony Iommi — Tone DNA & Signal Chain
Tony Iommi invented heavy metal. After losing the tips of two fingers in an industrial accident, he tuned his strings down — creating the dark, slow, heavily de-tuned riff vocabulary that launched a genre. His SG into a loud Laney, pushed with a treble booster, is the foundation of all heavy music that followed.

Upgrade Path
Start with the £200 rig to validate the tone is right for you, then upgrade in order of impact.
- Guitar first — body and pickup type define the foundational character. A sg-family guitar is essential.
- Amp second — this is where 60% of the tone lives. Tony Iommi uses a british-voiced amp.
- Essential pedals — Boost, EQ. These are not optional for this tone.
- Technique — pick attack, vibrato, and dynamics account for more tonal difference than any single gear upgrade at this point.
