PICKUP AND MAGNET DIMENSIONS:
The shorter housing (SJ) is for the neck pickup, while the longer housing (LJ) is for the bridge pickup. Each of the housings also have
different mounting hole distances. Both SJ and LJ Housings can work with both 4 and 5-string instruments, but you should check the width
of your strings against the magnet dimensions above to make sure there is sufficient string coverage. A rule of thumb for any pickup is that
the total magnet width should be the string width plus twice the distance the pickup is from the strings. So, If the pickup is 3/16” (5mm) from
the strings, with a magnet width of 3.10“ (78mm) the maximum string width would be 2.72” (69mm). If your string width is too wide for a J Pickup,
choose one of the EMG Extended Series Pickups, with a 4 inch (100mm) housing, where we have several styles of pickup available.

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 Instructions:
****Tips and Tricks**** Start your installation by:
1) Determine which type output jack your instrument has.
A Stereo 12B type is Included, but if you have a long panel jack
a SwitchCraft 152B Long Panel Jack will be required.
2) Remove the strings, remove any existing Pickups and controls
(remember the order and function of each control)
3) Determine a good spot for the Pickup Buss and make sure the
cable or wires from the selection switch will reach the Pickup Buss,
4) Install the EMG Volume and Tone Controls and tighten them in.
5) Then install the pickups keeping any excess cable under the pickup
rather than in the control cavity.
6) IMPORTANT: EMG Active pickups do not require a string ground wire!
DO NOT Reconnect the string ground, it is unnecessary.
EMG Models: J,JA,J-CS SET (4/5-STRING)
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 the long panel output jack and you had passive pickups
you will need a new stereo output jack, the Switchcraft 152B is recommended.
Soldering to the new jack will be required, see Diagram #7 on page 3.
2) Power Supply tips are on page 4. If your instrument has a battery holder,
you are installing this pickup with an older EMG, or you want to supply your
instrument with +18 Volts, see page 4 for tips to avoid soldering.
Installation Instructions:
2 Pickups, 2 Volume controls and Master Tone, no selection switch
J-Bass Style wiring
Refer to Diagram #2
1) Install the Pickups and route the Pickup cables to the control cavity.
If the cables are too long, keep any excess under the pickup.
2) Mount the Volume and Tone controls into the body / pickguard.
Plug the Neck Pickup Cable onto the Neck Volume Control.
Plug the Bridge Pickup Cable onto the Bridge Volume Control.
3) Plug a coax cable from the Neck Volume Control to the Bridge Volume
Control.
4) Plug a coax cable from the Bridge Volume Control the the Master Tone Control.
5) Plug the output cable onto the Master Tone control and connect the output
wires to the output jack by pushing the connectors on as shown.
WHITE wire onto the TIP (T) contact,
BLACK wire onto the SLEEVE (S) contact
BLACK Battery Negative wire onto the RING (R) contact.
6) Plug the RED Wires of the pickups onto the V+ Supply Buss (RED Shroud)
along with the RED of the battery clip.
Extra pins on the V+ Supply Buss are for EMG Accessories.
7) Put the battery in the insulating foam piece provided and place it securely in the
control cavity. We suggest that you plug in the instrument and test it before
closing the control cavity.

Installation Instructions:
EMG Models: J5, J5A, J5-CS SET (4 /5-STRING)
If your instrument has a selection switch:
Shown at the right is the EMG B245 Pickup Buss which is used for
instruments that have 2 pickups and a 3 position selection switch.
If you have a selection switch and want your installation to
remain solderless, you’ll need a B245 Buss.
Either send an e-mail to: sales@emgpickups.com
or call: 800 821-1446 to get the buss.
1) Install the Pickups and route the Pickup cables to the control cavity.
If the cables are too long, wind up the excess and keep it under the pickup.
2) Mount the Volume and Tone controls into the body.
Plug both Pickup cables onto the Pickup Buss (BLACK Shroud) as shown,
Refer to Diagram #4a
Bridge Pickup to position 1
Neck Pickup to position 2.
3) Plug a coax cable from the Pickup Buss (position 3) to the Master Volume
control as shown in Diagram #4b.
4) Plug a coax cable from the Master Volume to the Master Tone as shown.
5) Strip the insulation from the switch wires and Insert them into the GREEN
Terminal Block and tighten the screws with a small screwdriver.
The Bridge pickup goes to the BR Terminal
The Neck pickup goes to the NK Terminal
The Output of the switch goes to the O Terminal
If there is a ground wire coming from the switch, insert it into one of the black
terminals on the terminal block.
6) Plug the output cable onto the Master Tone control and connect the output
wires to the output jack by pushing the connectors on as shown.
WHITE wire onto the TIP (T) contact,
BLACK wire onto the SLEEVE (S) contact
BLACK Battery Negative wire onto the RING (R) contact.

If the instrument has a Battery Holder:
If your instrument has a 9 or 18 Volt battery holder you can still
use the EMG Connectors to supply power to the pickups.
Simply cut and strip the wires from the battery clip provided.
Twist the wires together (Red to Red and Black to Black) and
use the shrink tubing included to cover the connections.
Soldering the wires is recommended.
Cover these connections with the
