From the vendor
A reproduction of the third version of the Tone Bender germanium fuzz sold by Macaris in London in the late 1960s.
Project description
The Phobos Fuzz is a clone of the Colorsound / Sola Sound Tone Bender Mk. III. Using this PCB, you can also build a Baldwin-Burns Buzzaround. Just make sure to read the documentation because there are a few major differences between the two circuits.
The Tonebender was sold under a number of different brand names, including Vox and Park Sound. While the official Sola Sound version was just called the “Tone Bender” officially, the Vox version included the “Mark III”, and it was the direct successor of the “Mark II” (my Deimos project) so the Mk III designation has come to represent this version. It’s also commonly called the 3-Knob Tonebender to distinguish it from versions 1 and 2 that only had two knobs.
