Andrew Stockdale's searing, fuzz-soaked riff from Wolfmother's 2005 debut — the track that won the 2007 Grammy for Best Hard Rock Performance. Producer Dave Sardy tracked it at Sound City, LA, keeping ~10 vintage amps (Marshall Plexis, Oranges, Laneys, Hiwatts) on hand and switching between them for tonal variety. The dirt is fuzz, not just the amp: a Green Russian Big Muff is the documented studio fuzz, with octave-fuzz character (a Foxx Tone Machine is his live staple) for the screaming lead bite. Standard E, '73 Gibson SG.
