In PLAY mode, enter BYPASS or MUTE mode by pressing both foot pedals at the same time once (for BYPASS) or by holding them both down for more than half a second (for MUTE). Make sure your guitar is connected to the GuitarFX, and play the open string you wish to tune. The left digit of the display indicates the pitch nearest that of the open string. Look at the right digit of the display to determine if the pitch is correct. If the top four segments of the digit are rotating clockwise, then the pitch is higher than the pitch shown in the first digit. If the bottom four segments are rotating counterclockwise, the pitch is low. Tune the string until an 8 appears in the second digit, indicating that the string is in tune with the pitch displayed in the left digit. The visual guide on the next page shows you what you'll see on the display while tuning your guitar. 2 3 1 3. 4. 20 Using the Tuner 7 Changing Pitch Reference If you turn the VALUE knob while using the tuner, the display shows you the setting for the GuitarFX's pitch ) for the A reference, which is set to 440Hz (shown as note above middle C.
