(ACTIVE/PASSIVE PICKUP INPUTS)
SPECIFICATIONS
Input Impedance (Ohms) 250K
Input Referred Noise -130dbV
Output Impedance (Ohms) 2K
Current @ 9V (Microamps) 750
Battery Life (Hours) 200

GENERAL OPERATION:
The EXG is an active EQ circuit for guitar that simultaneously increases both low and high frequencies while decreasing mid-range.
The graph below illustrates the effect of the EXG. The thick black line displays the effect with the control all the way up (clockwise).
The flat black line illustrates the effect with the control all the way down (counter-clockwise) in the bypass mode. The EXG is continuously
variable from flat to maximum effect. The EXG is wired in series with the signal path, so there is an input and output.
The EXG has buffered inputs and can be used with passive pickups.
INCLUDED:
1 EXG Control
1 Battery Clip with Buss Connector
1 Stereo Output Jack (Battery Switching)

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

Installation Instructions:
EMG Model: EXG
Like all EMG Accessory products the EXG uses the 5-pin header as a standard.
Diagram #1 to the right shows how the plug-in connectors are installed.
Be sure to reverse the input connector as shown.
Since there are a variety of installations in which the EXG can be installed it
is impossible to show every installation in this data sheet. Some of the simpler
installations have been chosen. More diagrams are available at our website
http://www.emgpickups.com.
Diagrams #2 and #3 illustrate installations that have a single pickup and
do not use a selection switch.
Page 3 has diagrams that have 2 pickups and a selection switch.
Page 4 has diagrams that have 3 Pickups and use the B161 five-position
selection switch/buss. If you have the B161, refer to that data sheet where
more options regarding 3-pickup instruments are available.
Keep in mind that all of the EMG Accessory controls can be substituted for one
another since they all have buffered inputs and utilize the same 5-pin connnector.
So, if you decide you would rather use the SPC instead of the EXG, simply unplug
the EXG and replace it with the SPC.

Powering up the pickups:
If your existing pickup cables don’t have the connector for the
power buss, simply use some needle nose pliers and pull out the
V+ header and solder the RED Wires of the EMG Pickups to any
of the pins on the header. Also, don’t forget to solder the RED Wire
of the battery clip to one of the header pins of the buss as well.
If you are installing EMG-HZ Passive Pickups refer to
their diagrams. The Red Wire of the HZ Pickup is NOT
for battery power, it is a coil wire.

Diagrams #4 and #5 show the pickups connected to the B157 Pickup Buss.
To learn more about the B157 Pickup Buss, be sure to go to the EMG Website:
http://www.emgpickups.com. More diagrams are available at the EMG website.
The EXG or any EMG Active Tone Control is shown following the pickup buss
and then to the output jack. A master volume could easily follow the SPC
before the output jack.

3 Pickup Guitars using a selection switch:
The EXG Control is larger than EMG’s other accessories, so it is shown
installed in Strat* installations in the middle control position with the tone
control shown in the last control position.
Diagrams #6, #7, and #8 show a typical installation with a Volume/Tone/EXG in a
“daisy-chain” series wiring. The only difference between the the diagrams
is the order in which the controls are wired. All diagrams yield the same
results. The diagrams have been edited to show the EXG input, output,
and power (9V+). The pickup inputs, battery, and “ring”contact to the jack
have been omitted for clarity.
All diagrams also show the B161 5-Position switch buss. To learn more
about the B161 5-Position switch Buss, go to the EMG Website:
http://www.emgpickups.com.
Refer to Diagram #6
Start by installing the EXG as shown in Diagram #6.
1) Plug a coax cable from the switch output to the Volume control.
2) Plug a coax cable from the Volume control to the Tone control.
3) Plug a coax cable from the Tone control to the input of the EXG.
Be sure to reverse the connector on the input of the EXG as shown.
4) Plug the output cable from the EXG to the output jack.
5) Plug the Red wire from the EXG to one of the supply pins on the
B161 Switch Buss.
Be sure the 3 shunts are installed on the bypass header of the
B161 switch or you won’t get any output from the guitar.

Refer to Diagram #7
Start by installing the EXG as shown in Diagram #7.
1) Plug a coax cable from the switch output to the Tone control.
2) Plug a coax cable from the Tone control to the input of the EXG.
Be sure to reverse the connector on the input of the EXG as shown.
3) Plug a coax cable from the output of the EXG to the Volume control.
4) Plug the output cable from the Volume control to the output jack.
5) Plug the Red wire from the EXG to one of the supply pins on the
B161 Switch Buss.
Be sure the 3 shunts are installed on the bypass header of the
B161 switch or you won’t get any output from the guitar.
Refer to Diagram #8
Diagram #8 shows 2 active controls installed. This would be
similar to the X Series Pickups that use an active tone (VLPF)
and adding the EXG Control.
Start by installing the EXG as shown in Diagram #8.
1) Plug a coax cable from the switch output to the Volume control.
2) Plug a coax cable from the Volume control to the input of the EXG.
Be sure to reverse the connector on the input of the EXG as shown.
3) Plug a coax cable from the output of the EXG to the input of the VLPF.
Be sure to reverse the connector on the input of the VLPF as shown.
4) Plug the output cable from the VLPF to the output jack.
5) Plug the Red wires from both the VLPF and EXG to the extra 9V+
supply pins on the B161 Switch Buss.
Be sure the 3 shunts are installed on the bypass header of the
B161 switch or you won’t get any output from the guitar.
