The mysterious Sola Sound MK1.5 Tone Bender, which is pretty much a Fuzz Face, or a Fuzz Face is a MK1.5 Tone Bender – either way… just don’t try and bias it like a Fuzz Face.
You can the find history of the Tone Bender on Kit Rae’s Big Muff Page and also on David Main’s (D*A*M) Stompbox site
You could also use this layout for a standard Fuzz Face. Be sure to add the usual power filtering if you intend to run this off a power supply, as opposed to a 9V battery. There should be room on the board.
