Used and in great condition, the Chicago Stompworks Octave Up effect pedal delivers bold, vintage-inspired tones perfect for guitarists seeking a classic fuzz-driven upper octave sound. Housed in a durable metal enclosure, this true bypass pedal features simple, knobless operation for intuitive control over its edgy and harmonically rich effect. Designed to emulate 1970s-style fuzz/octave tones, it pairs exceptionally well with gain-sensitive amp setups and other distortion pedals. This pedal runs on a standard 9V DC center-negative power supply (not included), making it easy to integrate into any pedalboard. Whether you're chasing Hendrix-esque leads or adding texture to your solos, the Octave Up offers responsive performance in a compact package.
