Notes & Caveats
- No direct studio documentation for 'Opus Pocus' riff section, but all cited sources agree on Carvin DC200 with M22 humbuckers into Marshall JCM800 boosted by Boss SD-1 for this era.
- No numeric amp settings found; values estimated based on typical 1980s Marshall JCM800 metal tones and genre/era conventions.
- No evidence of additional pedals or modulation/time-based effects in riff section; only Boss SD-1 confirmed as boost.
- Reverb set to minimum based on source guidance ('minimum of reverb').
- Pickup choice inferred from 'bridge pickup (humbucker)' recommendation in Guitar World and genre-typical usage.
- Settings cross-referenced with genre and era conventions for accuracy. Jason Becker's 'Opus Pocus' riff section features a saturated, articulate 80s shred tone with tight lows, slightly scooped mids, and bright, cutting highs typical of late-80s neoclassical metal. The amp settings reflect his likely use of a high-gain Marshall or similar amp with minimal reverb and boosted presence for clarity.
