The last thing to solder is to close two
solder jumpers
indicated by “IN” under the first and fifth jack
connector. This normalizes the input to ground when nothing is plugged in. See the image below.
Unmount the connector board from the panel. As you can see some
male pinheaders
left. You will use
them in another step.
POTS BOARD
Next you will build the pots board. Firstly insert
three resistors
(15k) and solder them.
You should be
aware to let enough space for the 5 pin holes on the side
(you will be soldering a male pinheader
there later).
Take the
six potentiometers
and put them
on the board. They have to sit right on the
board and stand vertically. You can start
soldering only one leg of each pot, then check
the alignment and make an adjustment if
needed. Solder the other legs. Then let’s insert
and solder
two small buttons
.
