If MXR's M-108 10-Band EQ isn't heavy enough for you, check out its evil twin, the Kerry King 10-Band. Designed in conjunction with the legendary Slayer guitarist, this beastly, tattoo-covered pedal sports the same great features and hardcore construction as the M-108, but the King can punish two amps at once thanks to its dual outputs. Use it as a boost for solos or to create thrash-approved, scooped-mid rhythm tones. Create raging sustain and feedback while getting more thunderous low-end out of your rig than you ever thought possible. The Kerry King 10-Band EQ: Use with caution. And don't say we didn't warn you. Power: Two 9-volt batteries (some early models may not have this feature), or Dunlop ECB-004 18-volt AC Adapter - Footswitch toggles effect on/hardwire bypass (illuminated sliders indicates on) Ten sliders enable boost or cut up to 12dB at 31.25Hz, 62.5Hz, 125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 4kHz, 8kHz, 16kHz Separate Input Gain and Output Level sliders (+/- 12dB) Dual outputs for stereo applications.
