Hey, everyone. I've had an HD500 for about a year and a half and recently the tap/tuner button started misfiring. What I mean is that sometimes when I press it once, it registers as two times, making the tempo insanely fast. Also sometimes when I hold it down and it goes to tuner, it will register contact, when I release it, so then it exits tuner mode. Is there anything I can try to do before sending it in for repair? Any ideas would be appreciated.
