The MXR KFK-1 Kerry King Ten Band Equalizer was designed in conjunction with the legendary Slayer guitarist. This beastly, tattoo-covered pedal has all the functions of the M-108 times 2 with its dual outputs. The KFK-1 will help you shape thrash-approved, scooped-mid rhythm tones plus create raging sustain and feedback. It'll help you wring more thunderous low-end out of your rig than you ever thought possible. Use it with caution. And don't say we didn't warn you!
