Used Electro-Harmonix XO Knockout Attack Equalizer Pedal

Used Electro-Harmonix XO Knockout Attack Equalizer Pedal in good condition—an instant tone shaper for guitar or bass. This compact analog pedal uses a powerful dual band-pass EQ to scoop mids and emphasize lows/highs, delivering tighter, more aggressive “knockout” attack for riffs, funk, and leads. Simple controls make it fast to dial in punch and clarity, and it runs on standard 9V DC power with rugged XO-series housing for reliable gigging.
