Warranty
All EMG Pickups and accessories are warranted for a period of two years. This warranty does not cover failure due to improper installation, abuse or damage.
If upon examination the pickup is determined to be defective, a replacement will be made. Warranty replacement products are covered by this same warranty.
This warranty covers only those pickups and accessories sold by authorized EMG Dealers. This warranty is not transferable.
Installation notes:
The JV-HZ and JV-HZ 52 Sets consist of a Short (SJ-HZ) Neck Pickup and Long (LJ-HZ) Bridge Pickup. These JV-HZ Models use a side-by-side
coil design for noise-reduction and feature Alnico pole pieces for a warm, vintage tone. Alnico 5 poles are used in both JV-HZ Set pickups,
and in the Neck pickup of the JV-HZ 52 Set. Alnico 2 poles are used in the Bridge pickup of the JV-HZ 52 Set for a uniquely-smooth response.
IMPORTANT NOTE: String Ground (Earth)
It is common practice to use a bridge ground wire to reduce noise in instruments with passive pickups. An IDC connector is included to
attach your bridge ground wire to the EMG Ground Wire (single-ended). A “Ground Buss” and doule-ended Ground Wire is used to join all
common ground connections.

Insert the plug onto the 3 pin header
of the pickup as shown above.
Note the orientation arrow.
General Notes:
Every attempt has been made to make this a solderless installation.
There are some instances where this is not possible:
1) If your instrument uses a long panel output jack, soldering will be required
2) If your instrument has a selection switch or if the wiring is different,
vist our website (emgpickups.com) for more diagrams and video installations.
Installation
1) Diagram#1 shows how to install the pickup cable onto the back of the pickup.
Be sure the arrows are visible as shown.
Diagram #2 shows the color code of the cable, be sure to pay attention to the
colors when you are installing the pickup and interconnect cables.
2) The most common method of wiring J Bass Pickups is using the
Volume/Volume/Tone arrangement shown in Diagram #3.
If your guitar is wired in the same fashion, simply follow the diagram
and install the cables as shown.

Attaching the bridge ground wire
3) Refer to Diagram #4.
As mentioned on Page 1, it is common to “ground” (earth)
the strings on instruments with passive pickups.
Included with the system is a black ground wire with a single
solderless connector. Also included is an IDC connector for
joining two wires together.
Insert your bridge ground wire and EMG ground wire into the IDC
connector as shown. You don’t need to strip the insulation from
either wire. Crimp the connector with a pair of pliers until it snaps.
This will connect the two wires. The IDC connector can only be
used once, and cannot be “un-crimped”.
Push the solderless connector into the included Ground Buss
as shown in the diagram. This will ground the strings to the system.
