Hey there,
ive been wondering for so long (i am really amateur and begineer), ive red every tutorial and so, but for example there is level 1 and 2 and layout, but in description is "level 3 > output"... where is level 3 ? where do i found it?
Level will be a potentiometer. A potentiometer has three lugs, numbered 1, 2 and 3 from left to right looking from above. Level 3 will be the right lug. You should connect this to the output of the 3pdt switch, and onto the output jack
