Hashpipe was the first single to be released by the band from their untitled 2001 release (which has been dubbed "The Green Album"). A heavy guitar groove doubled by the bass is the focal point of the song - you'll need a dirty sound and a good deal of volume to replicate this. The guitar part shouldn't be too tough to play. Pay attention to the dynamics of the song - most of the verse is more restrained and palm-muted.
