Inspired by Analogman’s Sunface. Vintage germanium fuzz with roots in Arbiter Fuzz Face.
Analogman’s take on the Arbiter Fuzzface, is there more to say? Oh yes, it has an internal trimmer for the input’s sensitivity, which lets you dial in a fatter and more compressed tone or thinner and more transparent. It makes it an excellent tool for any kind of pickup, and if you switch between guitars a lot, we recommend making this an external knob.
There are plenty of versions Analogman did; the most famous one has NOS red dot NTK275 Germanium PNP transistors. (Spoiler alert – they cost a fortune). But what matters more than the brand is that they are low leakage and a certain HFE. WE recommend Q1 50-70 and Q2 90-110. This Little hint should drop the price for your build quite a lot.
