From ehx.com: Octavix delivers the definitive late 1960’s fuzzed out, octave up sound together with modern enhancements that update the classic concept. Housed in EHX’s rugged nano package, the Octavix features Volume, Boost and Octave knobs. Volume regulates the output level of the pedal. Boost controls the amount of fuzztone and Octave adjusts the volume of the octave above. A mini-toggle lets the player select between 9 or 24 volt power rails and determines the power supply voltage for the entire circuit. At 9V the pedals behaves like the classic, saggy fuzz box. At 24V the Octavix delivers a tighter sound and a richer octave tone. True bypass ensures maximum signal path integrity.
The new EHX Octavix is designed to deliver a late ’60’s Octavia-style vibe with an octave up and classic fuzz to transport you to a world of bell bottoms and purple haze. Sounds good, right? The Volume, Boost and Octave controls let you dial in the right vintage tone while 21st Century updates for the modern player include switchable 24/9volt power rails that bring on a tight or saggy sound, as well as true bypass.
