Monkey Wrench

Dave Grohl
The Colour and the Shape · 1997

Monkey Wrench opens The Colour and the Shape at a full sprint — a frantic single-note main riff and a chorus wall of high-gain distortion. Dave Grohl tracked the heavy parts on his Gibson Trini Lopez semi-hollow through a Mesa/Boogie Dual Rectifier, with the lighter verse and the bridge breakdown leaning on a Vox AC30. Producer Gil Norton double-tracked the rhythm hard left and right, and the dirt is all amp — no distortion pedals.
