I picked up a MK2 cab today and the sound pot wires were unhooked. I don't know which wire goes to what connection on the pot. There is 3 pins on the pot and I got a Yellow, Brown, and White wire. Which wire goes where??? Thanks for any help!
It is not real critical. You can hook it up and will probably work. Usually there is an input and a ground and the center is the wiper (adjustment).
You can use an ohm meter and find one that is at or near ground. That wire will go to one side of the pot. The other two shouldn't matter much. Just make sure the pot is working as that may be a reason it was taken off.
