The Tuner mode detection allows to use the tuner instead of the traditional way. By connecting your guitar on
dedicated input (MICRO 2) you can check on display current status of tuning. The bar with the GREEN colour will
indicate perfect tuning.
BLUE or RED colour (related of tolerance tuning) will suggest how to correct your instrument tuning.
