Now we take the tooth washer which comes with the footswitch and solder a wire to it.
If we ground the enclosure it will act like a shild. Ungrounded the shielding effect is much smaller.
The 125B/1590N1-enclosures aren’t rectangular, thus we need to mount the input- and outputjacks with a small angle. I use a piece of wire, which I put under the jacks (see in the pictures). Then I solder them.
Note: If you like, you can cautiously clean the areas arround the jacks again with PCB-cleaner.
If you use hot glue, make sure not to apply to much glue.
