Moving the pots to any position doesn't per se change the way they work. If they are now backwards, you've inverted the wiring, I'd say, and it would suffice to swap the two outer wires on each pot to have them work as they did before. Volume pots are normally logarithmic (that's to say : more sensitive at one end of travel than the other...); that would be a clue as to whether the wires have been swapped. Hope this helps.
