Z.Vex Fuzz Factory
The Z.Vex Fuzz Factory is a fuzz pedal made by the American inventor and musician Zachary Vex of the Z.Vex Effects company. The Fuzz Factory is based on, yet vastly expands the tonal palette of, classic fuzz-tone designs from the 1960s. Invented in the mid-1990s, the pedals are mostly handbuilt and painted in Minnesota, United States, with a budget line being manufactured in Taiwan. Custom Finishes. Each unit is handpainted, and while there is a stock design that adorns most models of the pedal, there have been several variations released in limited quantity, including sparkle finishes , kanji finishes (writing and labelling of controls are in Japanese kanji characters), Korean finishes (all controls labelled in Korean), and so on. These limited runs of custom paintjobs underscore the handmade, one-of-a-kind nature of the devices. From the earliest incarnations of the device in the mid-1990s, Jason Myrold painted all Fuzz Factories leaving the Z.Vex shop. Briefly during the mid-2000s the artist Laura Bennett assumed painting duties. Vexter Series Fuzz Factory. In December 2004, Z.Vex released a new model of the Fuzz Factory, called the Vexter Series Fuzz Factory. The Vexter series differs from the Handpainted version  in that it has a silkscreened enclosure and a shorter warranty period. This effectively lowers the price point, and makes both production easier for Z.Vex and allows the effect to become more accessible to musicians. The Vexter Fuzz Factory contains the same circuit as the original Fuzz Factory pedals, with the inclusion of modern touches such as an indicator LED and DC power jack for powering the fuzz with an adapter. As of August 2006, Vexter series Z.Vex pedal subassemblies are completed in Taiwan, but a large portion is still done in Minnesota. Variations and Followers. Soon after the rise  in popularity of the original Fuzz Factory, the Fuzz Probe was introduced. This version kept most of the circuitry the same, but added a voltage-sensitive copper plate affixed to, and extending downward from the bottom of the unit. This copper plate, hardwired to the 'Stab' control on the pedal, allowed for real time control by use of one's foot or hand. By varying the distance from appendage to plate, the self-oscillation effects of the Fuzz Factory (Probe) circuit could be tempered and played musically, similar to a Theremin. Several newer effects makers, such as Death By Audio , have introduced products which exploit the feedback-loop characteristics in the same way as the Fuzz Factory. Japanese manufacturer Zoom released a self-oscillating/feedback loop-derived fuzz design called the Ultra-Fuzz, which some have likened to be a "poor man's" Fuzz Factory. In addition, circuit bending is now a commonplace technique among experimental electronic musicians, with the principles employed in the Fuzz Factory being extended to include almost any electronic device. Muse frontman Matt Bellamy is perhaps the best known user of the Fuzz Factory. The feedback heard at the beginning of Plug In Baby is a  Fuzz Factory oscillating before Bellamy launches into the song's iconic riff. Bellamy also owns several guitars with a built-in Fuzz Factory which he came up with the concept and was built by Hugh Manson of Manson Guitars. The first such guitar was popularly known by fans as the "Silver Manson" but now named "Manson Delorean". It was retired after the Absolution era, but Bellamy still uses the Fuzz Factory in the studio and on stage. Since the Fuzz factory is very expensive, but the electronic circuit rather simple – with the PCB board containing only 13 parts – it's  a popular project in the D.I.Y Scene. Fuzz Factory users.
