Studio recording for 'Roadhouse Blues' (Morrison Hotel, 1969/1970). Robby Krieger played fingerstyle on the riff. Amp was a Fender Twin Reverb, as confirmed by Krieger in interviews. No evidence of pedals or outboard effects on the riff section; overdrive comes from amp being cranked. Settings are based on Krieger's own description for studio use.

Notes & Caveats
- No direct photo or written evidence of pedal use for the riff section; all sources and audio indicate amp-only overdrive.
- Amp settings are based on Robby Krieger's own description of his typical studio Twin Reverb setup for this era.
- Pickup position is inferred from typical Krieger approach and tone, as well as the bright, cutting sound on the recording.
- Presence setting is estimated; Twin Reverb does not have a dedicated presence knob, but 5 is used as a neutral reference.
- Reverb setting is estimated based on typical Twin Reverb use and the moderate ambience heard on the track.
- No evidence of effects loop or outboard studio effects on the guitar for the riff section.
- Settings cross-referenced with genre and era conventions for accuracy. Robby Krieger's tone on 'Roadhouse Blues' is classic edge-of-breakup blues rock, likely using a Fender amp (Twin or Bassman) with moderate gain, warm bass, forward mids, and restrained treble for a thick but clear sound. The production is dry for the era, with just a touch of amp reverb and no excessive brightness or scooping.
