Gibson DARK FIRE - Single String Up Mode; All Strings Down Mode

In this mode, Dark Fire automatically repeats the tuning process because new strings are
being tuned. Note: A string LED may shine solid white in this mode due to signal anomalies.
This is not a problem; proceed normally.
Single String Up Mode
This mode is for replacing only one or two strings (e.g., replacing a broken string).
Caution: Unlike String Up Mode, Single String Up Mode does not target any pitch but simply
puts tension on the string. Do not press the MCK too many times in Step (5) below, or the
string could snap from over-tightening. Three presses should put enough tension on the new
string for it to tune with standard tuning operations. Also, remember that no tuning functions
work if any portion of the string shorts to the bridge base or adjacent strings.
1. After installing a string as described previously, pull out the MCK and turn it counter-clockwise
until the b# symbol lights blue. The Display Matrix will also shine blue (Dark Fire is in the Blue
Bank).
2. Turn the MCK to the Rotating Arrow position, and press the Display Matrix until a green
“arrow up” symbol shows in the center of the Display Matrix.
3. Stop pressing on the display; the Rotating Arrow LED will shine blue and all string LEDs will
shine green.
4. Turn the MCK to the string LED that corresponds to the string you are replacing. The LED you
select will shine red.
5. Press the MCK's Display Matrix momentarily, a few times in succession, and the
corresponding Powerhead will start to turn and place tension on that string.
6. Once there is enough tension on the string for it to have a pitch, rotate the MCK fully clockwise
and press the Display Matrix momentarily twice. Strum the strings as usual to tune.
All Strings Down Mode
When changing an entire set of strings, String Down Mode causes all Powerheads to de-tension all
strings at the same time so that you can remove them all.
1. Pull out the MCK and turn it counter-clockwise until the b# symbol lights blue. The Display
Matrix will also shine blue (Dark Fire is in the Blue Bank).
2. Press the MCK momentarily twice; the Display Matrix shines red. Dark Fire is in the Red Bank.
3. Turn the MCK to the Rotating Arrow position.
4. Press on the MCK's Display Matrix, and hold it in until the string LEDs start to flash and the
Powerheads start to unwind. All 6 Powerheads will unwind their strings.
5. When the Powerheads stop turning, release the locking nuts on the tuner posts and you can
easily remove all strings.
