RCA Horn-Line Fuzz — Maestro FZ-1 Riff
Keith Richards treated the central guitar line as a temporary guide for a future horn arrangement, using a Maestro FZ-1 Fuzz-Tone to give it a sustained, brass-like character. Engineer Dave Hassinger reportedly applied substantial console EQ to make the primitive fuzz cut through, while the precise guitar, amplifier and settings remain disputed. Settings approximated from the documented session equipment. Source: Premier Guitar's Rolling Stones Gear excerpt and Guitar World.
