ToneBender variants

Beginning with the Maestro Fuzz Tone, which wasn't called a Tone Bender but became the basis of the first Tone Bender circuit, the Tone Bender was king of all fuzzes until the Fuzzface came along.  The two circuits are closely related, with the Tone Bender Mk1.5 being actually a clone of the Fuzzface, but they have their own special personalitites.
