The MCK’s LED display will show various symbols and colors and these will be explained in the various modes of operation available to you. During the tuning process, they will behave as follows:
String LEDs Display Actions During Tuning Operations: string not tuned = solid red
measuring frequency = red flashing Powerheads turning = yellow flashing signal clipping = solid blue
string frequency at extreme range = solid purple individual string in tune = solid green
all strings in tune = all LEDs flash blue 3 times
During the tuning process, the guitar will be nearly 100 percent muted. After the MCK is pushed back in, full volume returns.
