INTRODUCTION
Congratulations on your purchase of the Rob Wasserman Signature 6-string Cross-Over
Bass. Zeta’s Cross-Over Series instruments are designed to give the bass player the
ability to successfully produce the sound of an acoustic bass whether playing in a
strapped-on bass guitar position, or when played in an upright position on the endpin or
tripod stand. The Cross-Over is made from lightweight alder tonewoods and is designed
to be comfortable to play with the ergonomic chest brace. To properly maintain and
familiarize yourself with your instrument, please read this owner's manual completely.
Please Note: Keep this manual in a safe location for future reference.
warranty card.
PERFORMANCE APPLICATIONS
The Cross-Over™ Bass provides the best of both worlds – the smooth sound of a
fretless bass guitar, and the easily accessible feel of an upright bass. To play as a bass
guitar, simply place a standard guitar strap on the strap pins on the back of the Cross-
Over™ Bass. Upright style playing can be accomplished on either the Telescoping
Endpin or the ZOS-5 Tripod Stand. The arched fingerboard of the Cross-Over™ Bass
allows for both pizzicato style playing (with your fingers), as well as arco style playing
(with a bow – in this case, a cello bow works best).
CONTROL FUNCTIONS
VOLUME KNOB Controls the volume of the instrument signal output. This knob
is located closest to the bridge, near the center of the
instrument.
TREBLE
BASS
This is a 12dB treble boost/cut, located in the center position of
the three controls.
This is a 12dB bass boost/cut, located closest to the edge of the
instrument.
LINE OUT
A powered balanced ¼” mono-output jack. The volume knob
determines the output level of this jack. Use a standard "guitar"
¼” cord.
PICKUP SYSTEM
Zeta Music

Owner's Manual
The heart of your instrument is Zeta’s patented StradosÔ bridge pickup. Under each
string are special piezo pickups positioned to maximize tone and signal while rejecting
feedback. The Cross-Over’s StradosÔ pickup projects warmth and clarity at any
volume. The pickup has a full-frequency response of 20-20Khz. The pickup’s audio
signals are processed through an active preamp system internally mounted within the
instrument..
TELESCOPING ENDPIN AND UPPER BOUT GUIDE
These accessories convert the Cross-Over so that it can be played in an upright
position. Simply insert the telescoping endpin into the base of the instrument and turn it
clockwise until the screw threads engage and hold it in position. The upper bout guide
is screwed in place with the two thumb screws onto the upper back of the instrument,
and features thumb screws for adjusting the playing angle of the Cross-Over. The
upper bout guide is designed to simulate the contours of an acoustic upright bass, and
provides support of the bass by leaning against the player's midsection.
TRIPOD MOUNTING SYSTEM
The optional ZOS-5 Tripod Stand mounts in the lower body cavity, just as the
Telescoping Endpin. While the instrument is mounted on the ZOS-5 Tripod Stand,
please be certain that the tripod feet are fully expanded as the instrument could be
accidentally knocked over.
LIGHTWEIGHT TUNERS
Gotoh lightweight tuning machines are designed to hold the strings at pitch for long
periods of time without needing readjustment. Gotoh lightweight tuning machines have a
20:1 tuning ratio.
STRINGS
Please note: For optimum instrument performance, strings should be changed at least
once every month.

ZETA strings are available at your Authorized ZETA Dealer. ZETA strings are

INSTRUMENT CARE
CLEANING. Do not clean your instrument with chemical solvents such as benzene or
alcohol. Wipe only with a clean dry cloth or use a high quality non-abrasive instrument
polish.
SET UP. ZETA recommends that you have your neck adjusted seasonally by a
qualified instrument repair person or luthier, or at your local Authorized ZETA Dealer.
BRIDGE ADJUSTMENTS
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.
TRUSS ROD
The truss rod is located where the neck meets the body, and is recessed inside of the
neck. An allen wrench extension may be necessary to adjust the truss rod on some
models of Cross-Over™ Bass. 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. A 9-volt battery powers 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.
TROUBLESHOOTING
Don’t Panic!

String(s) Dead or Low Level Output
1. Check to see if the string is sitting properly on the bridge.
2. Check to ensure that the steel ball at the end of the string is in good contact with the
tailpiece. If necessary, scrape away any thread winding on the string that may be
preventing a clean metal-to-metal contact.
3. Try replacing the internal 9-volt battery with a fresh one.
