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.

Visual Guide to Tuning
Here are the 12 possible
pitches (a decimal point
indicates a sharp):
= no pitch detected.
The bottom four segments rotate counterclockwise
if pitch is low. The top four rotate clockwise if the pitch
is high. An 8 means the string you have played is in tune
with the displayed pitch.
Changing Pitch Reference
If you turn the VALUE knob while using the tuner, the
display shows you the setting for the Spitfire’s pitch
reference, which is set to 440Hz (shown as
) for the
A note above middle C. The possible range of values for
this setting is 35 to 45, which represents 435Hz to
445Hz.
When you turn the Spitfire on and off again, the
reference pitch is reset to 40.
While you are viewing
or editing the pitch
reference, the display
will return to pitch
indication if you do not
rotate the knob for
more than two seconds.
