Step 5: Soldering N 1/8" Output
-Now we will be soldering the wires to our output jack. (pictured is a 1/8" jack)
-Locate the GND, Left, and Right pins of your jack and solder the corresponding wire to them.
...most companies have a schematic layout of the pins on the packaging, if not, then try and trace which one will touch the tip of the plug (left channel), the "ring" (right channel), and the Ground (sleeve or shaft) of plug.
-Tinning the wires here will also make it easier to connect
