Studio recording, 1984-1985 for 'Killing Is My Business... and Business Is Good!'. Dave Mustaine confirmed use of B.C. Rich Bich and Marshall JCM800 for this era. No evidence of additional pedals or rack effects for the riff section; distortion from amp. No evidence of effects loop or studio re-amping for the riff. All evidence points to a straight guitar-amp setup for the main rhythm/riff.

Notes & Caveats
- No direct numeric amp settings found for 'Mechanix' studio riff; settings estimated based on Marshall JCM800 typical thrash usage and era.
- No evidence of pedals or effects used on the riff section; distortion is from amp only.
- Pickups inferred from period-correct B.C. Rich Bich specs and Mustaine interviews.
- No reverb or time-based effects audible or cited for riff section.
- If new evidence of pedals or rack effects emerges, update accordingly.
- Settings cross-referenced with genre and era conventions for accuracy. Mechanix features a classic early Megadeth tone: high gain but not oversaturated, tight low end, heavily scooped mids, and aggressive, biting treble and presence. Dave Mustaine typically used a Marshall JCM800 with a Tube Screamer boost, and the production is very dry with no reverb, matching 80s thrash conventions.
