The Mask Audio Screws is a two-knob octave fuzz that abuses an op-amp to deliver an ever-present octave, specializing in tones from the lo-fi to the gnarly. A three-way toggle switch allows for brighter and bassier voices.
The builder claims that this pedal will deliver the octave in the fuzz “no matter the guitar, no matter the situation” – judge for yourself in the videos below.
