Spaw- Is the AAPMT tuned to A-440, or is it variable? I tried to tune my moustache with my Korg electronic tuner and it doesn't seem to work. I think it's out of range. I tried it on my beard, also, sith similar results. Any suggestions? Is there a model that is adaptable to beards? Any advice you have would be sincerely appreciate. Thanks, BlueJay
