Or does the meter show open circuit (infinite resistance) thru the full range of rotation?

Well I figured out what it was, a piece of capacitor lead wire got down into the volume control pot and was shorting it out, so I flushed it out with some contact cleaner and now the volume control pot seems to be working fine now.
The biggest give away was that the volume control pot wasn't measuring open but it was being rather difficult to turn so I took some contact cleaner and sprayed it into the volume control pot and sure enough that piece of capacitor lead wire flew right out of the pot and it now rotates perfectly.
