I just got a brand new PRS Studio. I'll do the NGD thing in a few days when I can take some pics. It's an amazingly beautiful guitar but the trem arm does not seem to fit into the hole that it's supposed to go into. There's a little black washer there and I don't know if I'm just supposed to force that arm in there. It certainly doesn't want to go in easily. I've looked in the instruction manual, at the PRS website and Youtube and no one says anything about this.
