The Copilot FX Orbit is an insane frequency modulated fuzz, offering plenty of control to spew out some interesting sounds from wacky to spaceship to laserguns. How does it work? The frequency of the note at the input will move back and forth the center/reference point of the VCO, the result is mixed together so both frequencies (signal and VCO) will interact and force the output of the incoming frequency to vary (the total amount of of modulation will be the difference of both signals). For noise this thing is mondo extreme. The Orbit is only powered via a 9-volt DC adapter (center negative as most pedals). There are no options for battery usage.
