The frantic, palm-muted intro riff that detonates into One by One's lead single. Dave Grohl's rig from The Colour and the Shape onward was a Gibson Trini Lopez Standard — a diamond-soundhole semi-hollow — into a Mesa/Boogie Dual Rectifier, and All My Life leans on exactly that: tight, aggressive Recto gain in drop D, with the low end reined in so the fast muted picking stays surgical. Chris Shiflett doubles and layers. The dynamic shift from whispered intro to full-throttle chorus is in the picking hand, not a channel switch.
