4Owner's Manual

There are two thumb screws beneath the bridge. The bridge may be raised or lowered on both sides to accommodate your playing style. It is recommended that the strings be slightly loosened before making any adjustments. Do not use pliers on the thumbscrews as the instrument's finish and screws may be damaged. Also, intonation may be adjusted by changing the angle at which the bridge meets the strings.

DOUBLE ADJUSTING TRUSS ROD

The truss rod is located where the neck meets the body. Turning the truss rod clockwise adds tension and up-bow to your neck; turning the truss rod counter-clockwise relieves tension and adds down -bow to your neck. We recommend that you have your neck adjusted seasonally by a qualified instrument repair person or luthier, or at your local Authorized ZETA Dealer.

BATTERY

This instrument contains quiet pre -amplified electronics within the compartment on the back of the instrument. Two 9-volt batteries power the circuitry and should be changed after 1,000 hours of playing use. Plugging in the ¼" cable activates the preamp. When the instrument is not in use (overnight), unplug the amplifier cord from the ¼" jack so that the battery is not being discharged.
