The purpose of this project was to design and build a high quality, yet affordable, analog “fuzz” guitar pedal kit to be sold to other members of Cal Poly’s Audio Engineering Society. The Audio Engineering Society (AES) has hosted pedal-building projects in the past, but my project partner Michael Twardochleb first had the idea to build an original kit to be officially affiliated with the club. Michael had built other pedals of his own in the past, making him an excellent partner to have for this project. Our design was based on the classic Vox Tonebender’s circuit, which was in turn based on the Dunlop Fuzz Face pedal. Once a basic working fuzz circuit was assembled, we modified the design and components in order to suit our sound preferences and then discussed the inclusion of additional features. We also hosted AES meetings specifically for our project in order to generate interest and get input on what features people wanted to see. After settling on a design, we ordered a small run of prototype boards along with components and stompbox enclosures, built & tested them, and then presented them to the club before taking orders for an actual production run.
