AM-Era Valveslapper Grind — 12-String Riff
Published rig reconstructions identify a Vox Starstream XII 12-string feeding a Coopersonic Valveslapper and a blend of Selmer Zodiac Twin 30 and Magnatone Custom 410 amplifiers. That unusual combination accounts for the riff’s thick octave texture, sag and subtle modulation. The listed amplifier values follow the published reconstruction, while microphone details are representative.

Notes
Play the riff behind the beat and mute decisively between phrases. Keep the drive fuzzy at the edges but defined enough that the 12-string octave content remains audible.
