Up for sale is the clever and powerful Electro-Harmonix Knockout Attack Equalizer, complete with its original factory box.

Far more than a standard EQ pedal, the Knockout is a targeted attack equalizer featuring independent Low-Pass filter, High-Pass filter, and Dry signal controls. It lets you completely redefine the transients and voice of your instrument—turning muddy low-end into tight, chest-thumping chunk or injecting searing, punchy high-end clarity. It works wonders placed after distortion pedals to tighten up modern metal tones, or used as a secret weapon for shaping bass guitar tracks.

Condition:

• Cosmetic: Good condition overall. It has a few minor scuff marks from normal board use, but the chassis is structurally rock-solid.
• Functional: 100% fully tested and operating perfectly. All three control knobs, jacks, and the true-bypass footswitch function smoothly and quietly.

Key Features:

• Advanced Frequency Sculpting: Combines a 7-pole low-pass filter, 6-pole high-pass filter, and clean dry blend.
• Transient & Attack Control: Dial in crushing low-end punch or sparkling high-end cut on the fly.
• Complete Package: Comes supplied in its original EHX factory box (runs on a standard 9V battery or 9V DC negative-center power supply, not included).
