Electro Harmonix Knockout Attack Equalizer Pedal Video

The Electro Harmonix Knockout is a powerful two-filter combination pedal that makes your humbuckers sound like single coils and your Strat sound like a Tele. Use it after distortion for the heavyweight punch of the metal masters. Awesome on bass! Power the Knockout with either a 9 volt battery or an optional 9 volt power supply.
