Removing that pot isn't worth the trouble. Besides, if your soldering skills are shaky, you just do damage to the board, not to mention any static can possibly damage an IC during handling.
Here's a better idea; If memory serves me correctly, I believe the pot shaft has a cap on it, which is the part that sticks out a bit from the casing. You can pull this cap off the shaft. Looking at your picture, the cap end where the step is. You can use a pair of side cutters from the outside to GENTLY grip this cap, and pull it off. The pot shaft will still be sticking out of the casing. Grind the excess off with a Dremel, and put a piece of duct tape over the hole (once it's set to the desire volume, of course). That way, you won't run the risk of damaging anything internal, and there will still be enough shaft left to remount the knob if you decide to sell the unit later.
