I got a JTV59 brand new yesterday and I have noticed that sometimes the alt tuning knob (which changes the modeling knob light from white to blue) is sometimes unresponsive, then tries to correct it self on the next press. I pressed it once, nothing happened. Pressed it again, still nothing. About 3-5 seconds later it cycle through the presses. It also has been recognizing double presses for a single push, and even changing between white and blue all by itself in the middle of my playing. I have already flashed and reinstalled the newest firmware. What do I do?
