Nu metal is heavily syncopated and is based mostly on guitar riffs. Mid-song bridges and a general lack of guitar solos contrasts it with other genres of heavy metal. Kory Grow of "Revolver" wrote, "... [i]n its efforts to tune down and simplify riffs, effectively drove a stake through the heart of the guitar solo". Another contrast with other heavy metal genres is nu metal's emphasis on rhythm, rather than on complexity or mood, often its rhythm sounds like that of groove metal. The wah pedal is occasionally featured in nu metal music. Nu metal guitar riffs occasionally are similar to those of death metal.
