Notes & Caveats
- No direct source lists exact amp knob settings for the studio recording; values estimated based on typical Marshall JCM900 settings for 1970s blues-rock and the audible tone.
- No pedal use is confirmed for the riff section of 'Ruta 66'; Equipboard lists only a tape recorder mod pedal used on a different song.
- Guitar model inferred from era, photos, and genre; Pappo is strongly associated with Les Pauls in this period.
- Reverb is minimal and likely from the amp or studio room, not a pedal.
- If new evidence emerges of pedal use or alternate amp/guitar, settings may need revision.
- Settings cross-referenced with genre and era conventions for accuracy. Pappo's Blues 'Ruta 66' riff features a classic early 70s British blues-rock crunch with forward mids, warm but not boomy lows, and moderate treble. Pappo often used Marshall-style amps with Les Pauls, favoring edge-of-breakup to crunchy tones with little reverb and a present, punchy sound.
