Notes & Caveats
- No direct studio amp knob photos for 'Sin City' riff, but multiple sources confirm Angus Young's rig was SG into Marshall Super Lead with no pedals or effects for this era and song.
- Amp settings are based on a reliable forum post referencing a rig rundown (Source 2), but may vary slightly from the exact studio session.
- No evidence of any pedals or amp effects (reverb, delay, modulation) used on the riff section; all sources and audio confirm a dry, direct amp tone.
- If Schaffer-Vega wireless preamp coloration was used, it would be subtle and not a pedal/effect in the traditional sense.
- Settings cross-referenced with genre and era conventions for accuracy. Malcolm and Angus Young used Marshall amps set for crunchy, mid-forward British rock tones with little to no reverb, as heard on 'Sin City.' The tone is tight, punchy, and articulate, with moderate gain, strong mids, and a balanced top end typical of late-70s AC/DC studio recordings.
