One of the main effects will introduce the guitar, the face fuzz. Almost “ancestor” effect, but now also very popular. The planned in 1966, I built germanium transistor version.
They have been produced in several versions, and I have not even uttering the copies either. It uses Tungsram AC128 NOS transistors. Like to see is not very complicated circuit. Few parts to be added, but they are of high quality. It is the pair transistors to measure and sort if possible. In return, you can receive a real vintage sound.
Units used germanium PNP transistors. Small effects, great sound:
