Notes & Caveats
- No direct numeric amp settings found in sources; values estimated based on typical Marshall JMP settings for classic southern rock in early 1970s.
- No evidence of pedals or outboard effects used on the riff section; all sources and isolated tracks indicate straight guitar-to-amp signal.
- Pickup position inferred from tone and known Betts' preference for bridge pickup on 'Blue Sky' riff.
- Amp model and guitar confirmed by multiple reputable sources, but no studio log with exact knob positions found.
- Settings cross-referenced with genre and era conventions for accuracy. Duane Allman's 'Blue Sky' riff tone is classic early '70s Southern rock: edge-of-breakup with rich mids, slightly boosted bass for warmth, and clear but not piercing treble. Likely a Marshall or Fender amp set for singing sustain, with moderate spring reverb for space.
