DIY Pedal Tips: Eyelet Board Build Walkthrough

Published at : 23 Dec 2025

In this video, we'll walk you through the build process for an eyelet board pedal build. This build is for a one-knob germanium Fuzz Face, though the process is similar for other circuits. The Fuzz Face has a very low parts count, so it is an excellent choice for a first-time build.

The one tricky part of a germanium fuzz face build is transistor selection, as the original circuit is picky about transistor specifications and can sound poor with the wrong specs (which will result in the circuit being "biased" incorrectly). One of the most common ways to mitigate this issue is to use a trim pot in place of the 8.2k resistor, which we have done in this build. The trim pot allows for making adjustments to the bias, which allows for a wider range of transistors to be used.

Note that PNP silicon transistors can also be used in this build.
