The battery has a useful life of approximately 100 hours.
It's turned on when a cable is plugged into the guitar. To extend battery life,
please remember to remove the plug when you're not playing your guitar.
The battery status light is on the control cover. When the
battery is good, this red LED flashes for an instant when the guitar is plugged in.
When the battery is low, the light will glow continuously while plugged in. You
then have approximately two hours of battery life left. Finally, a distorted output
signal or a high-pitched whistle will serve as an audio reminder that the battery is dead.
Ground Loops
Sometimes when using two amps, there may be a loud hum when the
guitar is plugged into the second amp. Tis hum is caused by a ground loop. This ground
loop isn't the fault of the guitar (or the amps for that matter), but a result of
well-intentioned electrical safety codes. Ground loops can lurk wherever two pieces of
electronic equipment are connected. There is opnly one safe way to rid yourself of pesky
ground loops:
Use a direct box with a ground lift to isolate the two amps.
Plug the Magnetic end of the stereo cable into one amp and the Piezo end into the
direct box. Plug the direct box's output into a balances input on the second amp.
