I had the same problem, so I put a couple of layers of painters tape on pliers and very carefully pulled them out. I used new tape each peg so the teeth wouldn't start to cut through the tape.
You can also try to push them up with your hand through the sound hole, but I couldn't get them to budge at all that way.
I put flats on mine and I am now thinking of trying tapes also and dreading having to pull those little buggers again.
