Studio recording, 1976. Malcolm Young's rhythm guitar on 'Jailbreak' riff section. No pedals, straight into amp. No amp reverb or effects. Guitar volume and tone controls are bypassed/removed on this modded Gretsch. Pickup selector is bridge only. All evidence points to classic Marshall Super Bass setup, no effects, and the iconic 'dry' AC/DC rhythm tone.

Notes & Caveats
- No direct studio knob settings for 'Jailbreak' found; amp settings estimated based on era, amp model, and genre-standard practice for Malcolm Young's rhythm tone.
- No effects or pedals confirmed or audible; all evidence and listening confirms dry, straight-into-amp sound.
- Guitar is heavily modded: only bridge pickup wired, no tone knob, volume hardwired full.
- Presence setting inferred from forum advice to keep presence low for AC/DC rhythm ('keep presence at 2-3' - Reddit).
- No reverb or delay audible or mentioned in any source; classic AC/DC rhythm tracks are famously dry.
- Settings cross-referenced with genre and era conventions for accuracy. AC/DC's 'Jailbreak' riff uses a classic Marshall crunch with moderate gain, strong mids, and slightly boosted treble and presence for bite and clarity. The tone is dry with no audible reverb, reflecting 70s production and the band's raw, in-your-face guitar sound.
