I have seen a few of the headphone adapters on folks machines here. and the one Garrett is offering. I don't have an AT Pro yet but plan on it shortly. Has any one thought of doing a "pigtail" adapter that would have both the 1/4" female and the Garrett Male receiver at the back of the arm rest of the Pro? Thought it might be a good idea one on each side of the rod and easy to get to for both.
