Appendix C: Troubleshooting
If you encounter problems with Dark Fire, Gibson recommends that you take it to an authorized
service center. Although there are some procedures you can try yourself, be careful—if you have any
doubt about your ability to do any of these fixes, please consult Gibson tech support.
One or more strings don't seem to tune correctly, but the rest do.
There can be several possible reasons for this problem:
The nut slot too high and there's too much friction
The lock nut on the string post is not tight enough
The string was strummed too hard, causing it to go sharp
A sticky string bar in the saddle causes pitch detection to fail
The accuracy setting needs to be higher accuracy setting too low (refer to Function 7 table in
Chapter 7)
E-Function Correction is enabled (refer to Function 9 table in Chapter 7)
The tailpiece is set too low, so the string touches the bridge base and shorts out to it.
Observe what happens when you try to tune the problematic string. Here's what should happen:
You strum, the respective string LED should start flashing red to indicate that pitch detection is
active.
After 1 second, the LED should start flashing yellow (information is being sent to the neck
CPU, and the Powerhead starts to move).
After tuning the string, the string's LED turns green to indicate the string is in tune.
When the guitar is in tune, all strings flash blue.
If not, try these fixes:
Remove the problematic string and make sure the string bar is not inclined in the saddle, and
that you can move the string bar up and down a little bit; it must not be sticky in its saddle.
Sometimes just “unsticking” the string bar is enough to solve the problem.
Restring the string and tap the string bar gently. Check that the string bar is not inclined and
that the lock nut on the tuner post is set tight.
Reset the tuning system (refer to Function 101 table in Chapter 7), afterward disable E-
Function correction (this must be done manually; refer to Function 9 table in Chapter 7).
If you are still having problems at this point, change accuracy settings to a higher level (refer to
Function 7 table in Chapter 7).
If all else fails, tune the problematic string to your liking, and save as Custom Altered Tuning
preset.
The battery doesn't seem to charge properly
While this is extremely rare, the battery may need to be reset. To do this (work slowly and carefully—
take care that you don't damage any of the components!):
