CONDENSER MIC ADJUSTMENT (System 43 only)
* Be sure to remove the battery if the instrument will not be used for an
extended period of time in order to prevent possible damage due to
battery leakage.
The condenser mic is attached inside the body (behind the preamplifier) with a
flexible pipe that allows free adjustment of the mic's direction.
A variety of tone variations are achievable by changing the direction of the mic
head.

• When the guitar was shipped from the factory, the mic head is positioned
inside the body slightly pointed towards the sound hole and about 10mm
from the guitar's top. (You can see it from the sound hole.) This setting is
good for picking up the sound of the strings being plucked. (See diagram 1)

• When the mic head is slightly pointing toward the inside of the body this
