GENERAL OPERATION:
The EXB is an active EQ circuit for bass guitar that simultaneously increases both low and high frequencies while decreasing mid-range.
The graph below illustrates the effect of the EXB. 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 EXB is continuously
variable from flat to maximum effect. The EXB is wired in series with the signal path, so there is an input and output.
The EXB has buffered inputs and can be used with passive pickups.
INCLUDED:
1 EXB Control
1 Battery Clip with Buss Connector

Installation Instructions:
EMG Model: EXB
Like all EMG Accessory products the EXB 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 EXB 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.
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 BTC instead of the EXB, simply unplug
the EXB and replace it with the BTC.
All of the EMG Active controls use the same 5-pin connector
shown below.
Note: Reversed connector! Pins 1 and 2 are reversed.
Make sure the connectors are plugged on as shown.

Diagrams #5 and #6 show the pickups connected to the B245 Pickup Buss.
To learn more about the B245 Pickup Buss, be sure to go to
http://www.emgpickups.com. More diagrams are available at the EMG website.
The EXB 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 EXB
before the output jack.

This diagram illustrates an installation using the X Series pickups from EMG
that have an active Tone control. The controls are wired in the above order with
the master Volume control last in the circuit. If you are using
the Active Balance Control remember that a passive Tone control will not
function when it comes after the ABC Control. If you want a standard tone
control the VLPF will be required.
