In the world of boutique fuzz pedal effects, Analog Man Mike Piera’s creations are among the most well-known and respected due to his attention to detail. His Sun Face fuzz is his most popular and based on the original Arbiter England Fuzz Face which was first introduced in 1966, but unlike the original which was built with a range of poorly matched components and haphazard quality control, Piera’s are built like finely tuned machines with every component being carefully measured and tested. Fuzz connoisseurs like Eric Johnson have reportedly gone through hundreds of Face Faces until finding just the right one. In any fuzz based around germanium transistors, proper matching, leakage testing, and biasing are all critical in order to get the most musical and harmonically rich fuzz.
