Erafuzz Octavo Stone - Silicon Fuzz Octave Machine



The Erafuzz Octavo Stone recreates the fuzz tones of one the most influential stoner-rock bands nowadays. It’s a great silicon fuzz that generates an octave-up tone available from a second footswitch on the right side; creating a psychedelic sound perfect for solos. This handmade unit includes multiple switch configurations to give you more control over the fuzz tones. The true-bypass footswitch preserves the guitar sound, and the extra point to point soldering wiring connection on the copper stripboard ensures a full circuit performance. It operates with a 9V carbon-zinc battery or with a standard (negative pin) 9V external power supply.
