The Electro Harmonix Knock Out Attack Equalizer is a compact pedal that functions as a two-band equalizer with a distinctive control layout. Its primary controls are labeled "Attack" and "Knock Out," which adjust the high and low frequency content respectively. The Attack knob boosts or cuts the treble range, adding or removing presence and bite from the signal, while the Knock Out knob controls the bass response, allowing for a thicker or thinner low end. A third control, labeled "Volume," sets the overall output level to compensate for any gain changes introduced by the EQ adjustments. The pedal operates with a standard 9V DC power supply and features a true bypass switching system, ensuring that when the effect is disengaged, the guitar's signal passes through unaltered. The interaction between the Attack and Knock Out controls allows for a wide range of tonal shaping, from scooped midrange settings to aggressive, mid-forward tones, making it a straightforward tool for shaping the instrument's voice before it reaches an amplifier.
