Octave Master Boost

The Fuzzlord Effects Octave Master is an all-analog octave-up boost designed to stack with fuzz, distortion and overdrive pedals. Its ring-modulated analog octave circuit produces pronounced upper-octave harmonics, with the effect becoming particularly prominent when playing higher on the neck with the instrument’s tone rolled back. When stacked into gain pedals, it adds aggressive harmonic content and can produce grinding, synth-like textures. The circuit is designed for both guitar and bass, retaining low-end weight while adding upper-frequency definition. It also provides enough output to push amplifiers and other gain stages harder, making it suitable as both an octave effect and a boost for heavier, saturated sounds.
