I feel your pain. I have changed electric guitar strings a few times, even as a non-player, and I have even changed classical strings with no problem. This past week I proudly repaired the cracked neck on my son's acoustic and changed the strings while I was at it. I had never changed acoustic strings with pegs. I didn't break anything but I was cussing a couple of pegs flying out until I figured out the trick.

I thought the hard part was going to be repairing the cracked neck not the simple string change!
