Vult Freak DIY Kit
Assembly Guide

Thank you very much for supporting the Vult project!
I developed the Freak lter as a module for myself. I’m very glad
that more people have adopted it and have made it an
essential tool in their sonic arsenal.
Assembling this module is not complicated. But even if you are
an experienced builder, we recommend you to read and follow
this guide.
The build is divided into four sections.
1. Assembling the main board.
2. Assembling the control board (part 1).
3. Assembling the control board (part 2).
4. Final mounting of the module.
The control board is split into two sections because this will
simplify the cleaning of the board without damaging the
sensitive components like the OLED screen which can break
with liquids.
IMPORTANT: in this guide you will nd many sections
highlighted this way. Make sure you follow the indications.
I hope you enjoy the module, and if you like it, share the Vult
love with friends and enemies.

Disclaimer:
By purchasing a DIY kit you are aware that you are responsible
of the outcome of your build. Before starting, verify that none of
the parts has been damaged during the transport.
If your build fails, we can provide a limited service to help you
repair it. The cost will depend on the extent of the damage.
We want you to succeed. For that reason we tried to make this
guide as detailed as possible.

Assembling
the main board

In this section we are going to build the main board. You will need the
following parts:
• The Core board (with all SDM parts)
• 1 power connector (2x5 pins)
• 4 female headers (1x10 terminals)
• 1 push button (no cap)
You can see the elements in the following picture:

Start by soldering the 10 pin female headers.
Insert the header from the component-side of the board and hold it.
Solder only one terminal.
Verify that the header is correctly placed before soldering the rest.
The header should stand at 90 degrees.
Repeat the same process for all four headers.

NOTCH
Now you are going to solder the power connector. This connector
has a notch. The notch should be below the word POWER written
in the board.
IMPORTANT: Make sure you place it in the correct direction.
Use the same procedure as for the headers: solder one pin, verify
that the connector is correctly placed and then solder the remaining
pins.

To nish this section, solder the RESET button.

Your board should look like the pictures below.

Assembling
the control board
Part 1

We are going to assemble the control board in two parts.
IMPORTANT: Making it this way will simplify cleaning the board
without damaging sensitive components.
Locate the following components:
• The control PCB
• 9 jacks
• 2 push buttons (with cap)
• 2 axial resistors
• 4 male pin strips (1x10)
You can see the components in the following picture.
All components have to be mounted on the up-side (logo side) of
the board.
As a preparation, remove all the nuts from the jacks if they are
placed.

Start by soldering the two resistors. The orientation does not affect.

Continue with the pin strips using the following procedure. Insert
the pins from the bottom (as displayed in the pictures). Then solder
only one terminal.
IMPORTANT: verify that the pins are correctly placed and that the
angle is 90 degrees otherwise it will not be possible to connect the
main board.
Once you have veried that the pins are correctly placed continue
soldering the remaining terminals.
Repeat the procedure until all pin strips are done.

Place one of the two jacks displayed on the picture below. Hold it
with your nger and solder it. Then place the second jack displayed
on the picture and solder it.
IMPORTANT: make sure the jacks are correctly placed otherwise
the panel will not t correctly.

Place (but do not solder yet) the remaining jacks. Once you have all
jacks in position. Take the front panel and place it.
Gently tight two nuts on the jacks that are soldered. With all the
jacks in place, turn the board around and solder all of them.
NUT NUT

Place the two push buttons with caps. Make sure they are sitting
correctly on the board and solder them.
The control board should look as in the picture below.
IMPORTANT: now is a good moment to clean all the ux residuals
in your board. Use alcohol or ux remover. Make sure you clean the
space between the pin strips otherwise you may have undesired
noise in your module.

Assembling
the control board
Part 2

In this section we are going to nish the control board assembly.
Locate the following components:
• 5 plastic shaft potentiometers (blue color)
• 3 metal shaft potentiometers (green color)
• 1 OLED screen
• 1 screen holder
You can see the components in the following picture
As preparation, remove the nuts from the potentiometers if they are
placed.

In order to simplify the mounting of the potentiometers, take some
pliers and atten the terminals as show in the pictures below.
IMPORTANT: this is recommended because applying too much
force to the plastic shaft when placing the knob can break it. These
shafts break internally and become unstable or stuck.

IMPORTANT: When placing the potentiometers make sure they
enter completely through the holes and that they are sitting
correctly ovn top of the board.
