Based on the earliest 1969 perfboard version of the Big Muff, the device that started the whole family. The specifics of this early schematic produce a very massive, high-gain sound. Little Green Giant has more low end and gain than later variants, which makes it quite a distinct fuzz. The gain is very smooth, producing a long, sustained, singing character.
