About the trim pots: When you are nished with the build, the two BC108 transistors will need to be
dialed in using these internal adjustable trim pots. One of them is labeled “clean” and the other “bias”.

TRIM POTS

The internal trim pots featured on the Sun Fuzz allow the user the ne tune the overall
“feel” the pedal will have when engaged. The Clean trim pot adjusts the amount of fuzz
in the signal. The Bias trim pot adjusts the amount of voltage being routed to the transistors.
Both controls have a signicant impact on the sound.
Carefully insert the legs of the trim pots into the
PCB and solder in place on the back of the PCB.
Use a phillips head screwdriver to adjust the high
end frequency. Turn it to the right for more high
end, to the left to remove high end.
