The Analogman Sun Face Fuzz has been produced since the early 2000s and has been a favorite on the high-end fuzz market. Over the years, it has been produced with a wide variety of transistors, which each provide a different tonal footprint. While some rare chip sets can fetch high prices, there are plenty of more accessible models as well. 

The Sun Face is built with both Germanium and Silicon transistors. Germanium models can be found here. All models are available with or without a "Sun Dial" middle knob which adjusts the pedal's bias, taking the place of an internal trim pot on the 2-knob models.
