Re: 2 meg pot, what the heck do I do with that?
If you've got a tone control you that gives you a good range of cut (subtle in the upper half, but still effective at warming the guitar up without removing the clarity) then you might want to give it a whirl as a volume control,especially if you find your self getting a bit muddy or your rig is not as open as you'd like (a bit to much mids and not enough top end sparkle). Other than that if you are happy with what you got toss in a drawer and use it as a spare if you ever need it.
