The Indigo Fuzz was the result of simply wanting to create a fuzz that has the tonal qualities of a great germanium based fuzz without the inherent problems that occur with germanium based fuzzes. Those problems include; inconsistent performance because of temperature stability; deterioration over time because of the nature of germanium; PNP design making the use of a power supply problematic, and, possibly the most important fact: there simply aren’t many quality NOS germanium transistors left!
The Indigo has great tonal depth with a moderate amount of gain that does not mush out or get uncontrollable. It stays tight allowing chord detail to ring out true. The Indigo is a fuzz broadens the useful envelope of what a fuzz can do and adds a distinct character to rhythm and lead work.
