This evergreen nineties classic rides the fine line between an instrumental theme and a solo. That guitar part is such an integral part of the song that it’s impossible to imagine “Zombie” without it, which is the ultimate proof of a well-crafted solo.
Interestingly enough, even though Noel Hogan is the main guitarist of the band, singer and main songwriter Dolores O’ Riordan is the one who plays that solo on her distorted Gibson ES-335. Use a standard overdrive pedal, turn up the gain and add a little reverb to help the notes blend into each other.
