Electro-Harmonix Knockout Attack Equalizer Reissue Pedal

Expand the tonal limits humbucker-equipped guitar with the Electro Harmonix Knockout attack equalizer pedal. This guitar equalizer pedal helps you shape your tone by cutting the low end or contouring the upper mids via three user-friendly knobs for lows, highs and overall mix level. Click the switch on the signature tough metal chassis to transform your deep, husky humbucker tones to Strat-style bite, or take your single coils to Telecaster-level pop and twang. Place the Knockout after your distortion pedal in the chain to recreate the sounds of classic metal.

  • Tweak upper mids with a six-pole filter
