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 #5 below.
2) Some instruments may already have a battery holder installed and in that case
soldering may be required, see the diagram at the bottom of page 3.
3) Instruments with two pickups may need soldering to the selection
switch in some installations.

Soldering to the 152B Panel Jack:
If your instrument has a long Panel Jack like the one below
you will have to solder the output cable as shown.

Using the 45-TW-X Push-Pull Pot
The Push-Pull Pot included with the EMG-45-TW-X allows you to choose between
two internal pickups, single-coil and dual-coil. The Push-Pull Pot has two seperate
sections described below.
Refer to diagrams #1 and #2
1) The push-pull pot has a switch section (DPDT) that lets you choose
between the single-coil sound and a dual-coil sound by pulling or pushing
the pot shaft up or down. You have the option of having the single-coil
sound in either the up or down position and the same for the dual-coil sound.
Diagrams #1 and #2 show how to connect the 45-TW-X pickup cable to choose
either option. Select the diagram that suits you and push the cable
connectors onto the single line 6 pin header.
Simply flip cable connectors 1 and 2 to change the wire order and this
will choose between the two options.
Connector 3 remains the same for either choice.
Refer to diagrams #3 and #4
2) The pot section (25KA) can be used either as a volume control
for the pickup or, it can be used as the master volume for the guitar.
Diagrams #3 and #4 show how to connect either opition.
Use the dual-line 10 pin header and push the cables on and
install the shunts as needed onto the labeled headers H1 thru H5.
Use diagram #3 if you have a single 45-TW-X installed in your instrument,
or have two or more pickups in your instrument and want to use the pot as the
volume control for the 45-TW-X Pickup.
Installing the shunts on positions H3 and H5 sends the pickup signal
to the wiper of the 25K Pot, and the output of the 25K Pot is at position H1.
Diagram #4 allows you to use the 25K Pot independently of the pickup output.
By taking the output of the pickup from position H4, the volume control is now
available to use as a master volume with H1 and H2 being the input and/or output
of the volume control. H1 and H2 positions are interchangeable.
Position H4, now the output of the pickup, would typically go to a selection switch
or a pan-pot. Don’t forget to install the shunt on H5.
