Ultra Jazz 5
TM
Installation Instructions
Important Note: The cover dimensions of
the Ultra Jazz 5™ are not the same as 5-
string Fender Jazz Bass
®
. The Ultra Jazz
5™ can therefore NOT be installed as
direct replacements on these basses
without modification.
Dimensions and String Spacing
The neck (DP547) and bridge models (DP548)
are the same length, 3.725” (94.6mm). String
spacing is 2.72” (69mm) for the DP547 and
2.836” (72mm.) for the DP548.
General Instructions
If you have purchased our pickup to replace one
that is currently in your guitar, do the following:
•
Remove your old pickup carefully. Installing
your new pickup will be much easier if you
unsolder your original pickup cleanly, rather
than cut its wires. Make a note of exactly
where the old pickup was connected as, in
most cases, the new one will go to the same
place.
•
Use a soldering iron with a fine tip (25 to 45
watts) and thin rosin core solder for all
connections.
•
If you intend to use a miniature switch with the
pickup, try to be as clean as possible with the
solder connections to avoid short circuits or
damage to the switch. DiMarzio offers two
Push/Pull Potentiometers, the EP1200PP
(250K) and the EP1201PP (500K) with
double-pole, double-throw miniature switches
built in. The switches perform exactly like
separate miniature switches, and we
recommend them in situations where you do
not want to drill extra holes in the face or
pickguard of your instrument.
IMPORTANT
: Although other brands of pickups
may have the same color wires as DiMarzio
,
the connections are not necessarily the same.
For our pickup to function properly, you
must
follow these instructions.
Standard Wiring
The Ultra Jazz 5
TM
is a humcancelling pickup
with two coils, which are connected internally in
series. The wiring consists of a red, a green and
a gray wire.
Solder the
RED
wire to the hot connection in the
guitar’s circuit. In most cases where you are
replacing a pickup, the
RED
wire will be
soldered to the same place as the hot, or center
wire of the original pickup. The
GREEN
and
GRAY
wires are soldered to ground. The ground
connection is usually made to the back of a
control.
If you install this pickup in a guitar with other
pickup types and the pickups are out of phase
when they are on together, solder the
RED
and
GRAY
wires to ground, the
GREEN
wire to hot.
Phase Switch
Phase switching can only function in an
instrument with two or more pickups. The effect
will only occur when both pickups are on, and
will be most obvious when the pickups are at
approximately the same volume. Only one of
the pickups should be wired to the phase switch,
and it makes no audible difference which pickup
you choose. The switch is a double-pole,
double-throw type: DPDT (DiMarzio catalog
number EP1106) or push-pull pot (EP1200PP or
EP1201PP):
The wire labeled
HOT OUTPUT
is connected to
the same point as the original pickup. The wire
labeled
GROUND OUTPUT
is soldered to a
ground connection, such as the back of a
control.
Component Values
The Ultra Jazz 5
TM
will perform well with 250K
ohm or 500K ohm controls. The EP1202 1-Meg
tone control can also be used. Higher-resistance
controls offer a little more power and extended
treble response. Using 250K controls will result
in a little warmer sound and a slight drop in
power. If your bass uses a blend pot for pickup
selection, we recommend a value of 500K.
IMPORTANT
: To avoid compromising the
performance of the Ultra Jazz 5
TM
, do
not
use
25K ohm controls.
Additional Notes
Wiring diagrams and technical information may
be found on our website:

All DiMarzio pickups have been potted in an
exclusive wax formula to eliminate squeal and
subdue extraneous noise. For further noise
reduction, we recommend shielding the entire
guitar internally with DiMarzio
Shielding Tape
(EP1000). This will eliminate stray hum fields
from the circuitry of your guitar.
