7Using the Tuner
To Tune Your Guitar
1.In Play mode, enter BYPASS 
or MUTE 
mode by pressing the Program Up and Down buttons at the same time once (for BYPASS) or by holding them both down for more than half a second (for MUTE). The display will now show tuning information.
2.Make sure your guitar is connected to the Spitfire, and play the open string you wish to tune. The left digit of the display indicates the pitch nearest that of the open string. If the # decimal point is lit, the note is a sharp. If it is not lit, the note is a natural.
3.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. The more the pitch is off, the faster the rotation. If no pitch is detected, you’ll see a dash in the left digit.
4.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 what you’ll see on the display while tuning your guitar.
Remember, the optional footswitches work the same way as the Program Up and Down buttons. Step on both footswitches once to enter BYPASS mode, and hold them down for more than half a second to enter MUTE mode.
