Question: When I press one of the touch buttons (Vocal, Guitar, Looper etc.) the LED light comes on, but it also makes the light come on in other touch buttons! Is my unit defectiveAnswer: No, your unit is fine - this is a combination of the lights reflecting off the inside of the casing, as well as the way signals are sent up an LED ladder. You might also notice that when you use Naturalplay, and the orange LED flickers, it also sets off the red clip-light. This is also normal, and your unit isn't clipping - that is, unless all the level-LED's are lighting up brightly. A faint red flicker when Naturalplay comes on is nothing to worry about. Both this, and the touch button LEDs coming on, will have no effect on your audio signal.User-added imageUser-added image
