Need to replace Subwoofer volume control


I have an old M & K subwoofer a friend of mine is going to buy. It's a really good sounding sub. The rotary switch that controls the volume is really touchy and static-y when touched or adjusted. I thought it something we could replace ourselves.

Is there anything specific to a volume switch in a sub? Will most any switch work? I plan to remove the plate, remove the switch and get any numbers off of it.

Is there anything I should look at as a potential problem?

Stonedeaf...NOT Linear taper. It should be Audio taper, but these are so hard to find that Log taper is usually substituted. Characteristic of the original pot could be determined using an ohmeter once you get the thing out of the circuit.
Drew_eckhardt...Any time two pots are ganged there can be a tracking error. Why would a log pot be made as a series of linear segments? Seems to me that this would be more difficult to make than a straightforward log taper.
