Installation notes:
The SRO Pickups are open-coil style passive pickups. Models OC-1 Neck and Bridge feature pole pieces spaced apart in a Standard
Tune-o-Matic string spacing. The OC-1 Neck Pickup is very much a standard Humbucking style pickup featuring specifications
similar to older vintage pickups. The OC-1 Bridge Pickup on the other hand features much higher inductance and resistance specifications
yielding a more powerful pickup designed for the bridge pickup position on the guitar. Both pickups feature an Alnico 5 Magnet and steel poles.
The connector system allows an easy method of interchanging pickups. The SRO 5-Wire Cable and wire legend are compatible with all other
EMG-HZ Pickups, so any EMG-HZ Passive Pickup can be installed with an SRO Series Pickup. The 5-Wire cable allows Series/Parallel switching
or simple single/dual-coil combinations can be used. For more information go to http://www.emgpickups.com.
SPECIAL NOTE: The Red Wire of the HZ Pickup is NOT for battery power, it is a coil wire.
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.

EMG Models: SRO OC-1 Neck / Bridge
General Notes:
Diagram #1 shows the installation of the Pickup Cable.
Be sure to install it with the terminals as shown in the diagram.
Diagram #1
Diagram #2 shows the Pickup cable itself. The cable is pre- wired
as shown for “Series” wiring typical of Humbucking Pickups.
If you wish to reverse the phase of the signal refer to Diagram #3.
Send the Red wire to ground with the Shield and use the Green wire
for output. In both cases the Black and White wires are hooked together
and covered with an insulator.

connecting the two wires together. Insert the bridge ground wire,

and the connector wire into the IDC connector, crimp the connector
with a pair of pliers until it snaps and this will connect the two wires.
You don’t need to strip the insulation from the wires.
Push the black connector onto terminal 2 (GND) of the volume control
as shown in the diagram. This will ground the strings to the system.

If your instrument has a selection switch:
Shown below 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 into the Pickup Buss (BLACK Shroud) as shown,
Refer to Diagram #7
Bridge Pickup to BR IN
Neck Pickup to NK IN
3) Plug a coax cable from the Pickup Buss (OUT) to the Master Volume
control as shown in the diagram.
****Tips and Tricks****
Start your installation by:
1) Remove the strings
2) 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.
