Mick Thomson relies on his signature Rivera KR7 head. It’s a beast of an amp at 120 watts, voiced for tighter low-end and boosted mids to punch through the many layers of Slipknot’s music. The matching cab has massive headroom to keep the sound as pristine as possible. He’s also been seen more recently playing through an Omega Obsidian for the sixth LP We Are Not Your Kind. Mick’s setup is a little more tricky to capture perfectly, as Rivera amps are a small company with a very niche sound, but an EVH 5150, Mesa Boogie Mark V or Synergy amp will get you into the same ballpark.

Pedals
Both guitarists have relatively simple pedalboards and rackmount setups, as the high-gain amp channels do most of the work. On the rare occasion Slipknot use a clean tone, they’ll accompany it with some ambient effects. Jim Root has two MXR Carbon Copy delays set to different delay times and controlled backstage by his guitar tech. He has another one onstage for any crazy oscillations and a Cry Baby Wah used during solos or passages, such as as the pre chorus on Before I Forget.
Other effects such as the Boss Noise Suppressor stay on the rack as an “always on” effect ensuring silent, sharp staccato. Clean effects like the EHX Holy Grail Reverb, Micro POG and Maxon Phaser and Auto Filter are used more sparingly.
