Installation notes:
The EMG-40-TW has a variety of ways it can be wired into a bass. The diagrams included are limited to the most popular because of space.
The additon of the plug-on PC Board on the Push-Pull Pot adds further flexibility as you will see in the diagrams. We suggest you look fully at the
installation diagrams included in this sheet along with the B157 Pickup Buss data sheet included in this package before beginning your installation.
The Push-Pull Pot allows you 2 options as a volume control as well as 2 other options using the pot as a tone control. If you don't see a diagram that
fits your instrument directly, or you want to do something completely different, contact our technical department and we'll create a diagram you can
follow for your installation. Certain limitations apply...
IMPORTANT INSTALLATION NOTES:
1) Only one 9-Volt battery is required to power the pickups and any
accessories such as the SPC, RPC, EXG, AB, PA-2, and Pi-2.
Use an Alkaline or Lithium battery for longest life.
2) The Volume Control included with the EMG System is 25K Ohm.
This value is required for the system to work correctly.
3) A stereo output jack (12B) is included with the EMG Pickups;
it grounds the black battery wire to turn on the pickups when
the plug is inserted into the jack. If you are replacing passive
pickups, make sure to use the jack included. If your guitar has a
long panel jack make sure it is a stereo type, a Switchcraft 152B
is recommended.
4) When installing any EMG Active Pickup, DO NOT connect the
bridge ground wire. This wire is usually soldered to a volume or
tone control casing and goes to the bridge. This wire grounds the
strings and uses them and your body as a shield against hum and
buzz. It also creates a shock hazard.
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.

In Dual-coil mode, coils C1 and C2 are active.
In Single-coil mode, coils C2 andC3 are active.
EMG Pickups are shielded internally and DO NOT require string
grounding. This greatly reduces the possibility of reverse
polarity shock from microphones and other equipment.
5) EMG Active Pickups have very little magnetism compared to
passive pickups. We recommend you adjust the pickups as
close to the strings as possible. Sustain and string movement
will not be inhibited by close adjustment.
