Look up onUp for sale, an Electro-Harmonix Octavix in mint condition, complete with the original box, factory paperwork, and power supply. This unique stompbox pairs a classic fuzz with a frequency doubling circuit, producing a range of distorted effects backed by ring modulated overtones. The intuitive set of controls include Volume, Boost, and Octave knobs, with Boost governing the amount of fuzz being applied, and Octave governing the volume of the octave-above signal. Additionally, a 9/24 mini toggle at the heart of the interface determines the power supply voltage, behaving as a classic saggy fuzz of the mid-1970s when powered by 9V, and producing a richer octave tone with a tighter sound when set to 24V.The original box, factory paperwork, and power supply are included.
