How we label sources
- Verified artist gear Confirmed directly by the artist or their team. No items carry this label yet.
- Reliably sourced report Named in a published gear feature or interview (e.g. Premier Guitar Rig Rundowns, guitar magazines).
- YouTube / community reconstruction Compiled from YouTube rig tours, Wikipedia or fan archives. Treat as a starting point.
- Suggested alternative Boutique/budget clones are our editorial suggestions, not claims about what the artist uses.
Gear, prices and listings change. Owning the same gear won't guarantee an identical tone: technique, settings, recording, signal order and modifications all matter.
