Brown-Sound Arpeggio — Phase 90 Rhythm & Doubled Solo
Eddie Van Halen’s early chain centered on his bridge-humbucker Frankenstrat, a variac-controlled late-1960s Marshall Super Lead and a Greenback-loaded 4x12, with Echoplex ambience around the recorded guitar. Eddie and later effects histories identify the MXR Phase 90 on the song, including the solo, which was doubled with an electric sitar. Exact album-session control positions remain disputed, so settings are approximated from the documented early rig and Eddie’s reported slow Phase 90 setting.
