Five Finger Fuzz Build Guide & User Manual
Five Finger Fuzz is a passive diode fuzz Eurorack module with switches for changing which diodes are included in the circuit.
It's based on the simple passive fuzz designs that others have come up with (eg: Yan's Patchpals), but we added the switching
for more fuzz fun. This kit includes everything you need, including the PCB, front panel, all the components and a build guide.
The design uses 2 different kinds of diodes and it comes with a selection of different types to choose from, including some
Soviet military germanium diodes.

Note: This is a passive module. It may or may not cooperate with your other modules. It will not compete with your favorite distortion module. It will
not cause nausea or vomiting. Some people think passive modules don't belong in a proper Eurorack setup. Others are the type that are known to eat
ice cream in bed and put black tape over the warning light on their car's dashboard. You'll have to decide if it's right for you before proceeding.
Building the Module
This kit should be easy to assemble for a beginner. With that said, you will need to bring some basic soldering skills. You’ll also need a soldering iron,
some solder, and a pair of flush cutters. The following step-by-step instructions will lead you through the build process. If you have any questions,
send us an email and we’ll try to help.
Step 1: Gather the Parts
Lay everything out on a table, to make sure it’s all there. You should have a green PCB and a black front panel. The components that aren’t diodes,
include the following:
One 3mm red LED and one 180 Ohm resistor for the LED (the component with the brown, grey, brown stripes).
(If you decide to use a different LED, you might need to swap out the resistor to match)
One 10K linear taper potentiometer (also known as a “pot”). This is a trimmer-style pot that doesn’t allow you to attach a knob. If you want a
cool knob on your module, you’ll want to switch this out for a pot that’s designed to have a knob on it.
Two 3.5mm jacks and nuts
Five miniature SPDT on-off-on toggle switches
Two M3 x .5mm mounting screws
We’ve included an assortment of diodes. You’ll need four diodes
of the same type
, and four diodes
of another type
to make the module, but you can
choose which diodes you’ll use. Each type potentially has a different fuzzing effect, so you’ll want to keep them all in case you want to experiment with
changing the diodes later. In your kit, you should have four of each:
1N4001 power diodes (the black cylinders with a grey stripe)
1N4148 signal diodes (the little glass ones)
5mm LEDs (yes, LEDs are diodes!)
Point contact Germanium diodes (the larger black capsules)
