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.
Then use hot glue or super glue to glue the washers to the jacks.
If you use hot glue, make sure not to apply to much glue.
Screw the pots and switches in the enclosure. Put two layers of tape on the pots to ensure the housing can’t touch the soldered points.
Note: The letters correspont to the characteristic of the pots: 1x100kA (log), 1x100kB (lin) und 1x100kC (rev log).
