They are often called "dual concentric" pots.

No idea where to get them, except from guitar suppliers at insane
prices. For example:
http://www.stewmac.com/shop/Electronics,_pickups/Components:_Control_pots_and_knobs/5/Control_Pots.html
Sure, the prices include the special knobs, but they are still very
expensive pots.
