THE SOUND THAT CREATES LEGENDS
Chorus
Owner,s Manual
P/N 049106
INTRODUCTION
Your new Fender®Ultimate Chorus amplifier is a fine musical instrument that will deliver great tone and pleasure for
years to come. It combines many of the great
tures that have made Fender
®
amplifiers the only serious
musical
fea-
choice of guitarists for over 45 years, with a few new tricks
of its own.
The most striking tonal feature of the Ultimate Chorus amp
is its fat, full-range chorus. Unlike many other chorus
designs that can make an amp sound thin or “washsy”, our
classic analog circuit actually
adds
depth and dimension to
any style of playing— whether you’re playing rhythm or
solo. Also, besides the basic Volume, Treble, Mid, Bass and
Reverb controls in the Normal channel, the Ultimate Chorus
features completely independent Reverb and Tone controls
in the Drive channel.
The DRIVE channel also features exclusive Fender
®
Pre- &
De-Emphasis Distortion circuitry based on unique Pre and
Post clipper voicing filters. These filters were designed to
simulate the preamp tone settings and speaker output of an
overdriven tube amplifier. You get the searing smooth
highs backed by deep punch that stack amps are known
for. The MID BOOST switch provides a second pre-emphasis voice and the PRESENCE control provides continuous
variation of the high frequency content in the de-emphasis
voicing. The extended range, three band equalization circuitry is after the distortion and can be used to further modify the overall sound of the amp. In addition, a true, stereo
chorus circuit utilizing two 65-watt power amplifiers gives
this amp that lush, stereo chorus sound. The Fender
®
ULTIMATE CHORUS is one of the most “Expressive” amplifiers
ever made.
In addition to convenient features like All Front Panel
Mounted Controls and Jacks, the ULTIMATE CHORUS features a detachable footswitch for selecting the Drive
Channel and for activating the stereo chorus circuitry.
These switching functions are sent over a standard 1/4
inch phone plug for ease of connection or extension of the
footswitch to remote pedal boards. The versatility of the
ULTIMATE CHORUS is greatly expanded by the individual
mono and true, stereo effects loops. These patch points
allow for a wide variety of external effects connection
schemes and amplifier slaving configurations. They also
provide for direct connection to recording and sound reinforcement mixers.
Last, but definitely not least, the Fender
®
ULTIMATE CHORUS packs a new stereo power amp section based on a
radically underdamped design that interacts with the
speakers in much the same way as a tube amplifier does,
producing sparkle and punch with an increase in apparent
loudness and power that defies comparison to other similarly rated units. These amps are LOUD, and the Fender
Special Design 12 inch speakers can reliably put it out, day
after day.
This manual is designed to familiarize you with your new
amplifier and to acquaint you with its many fine features.
Read it carefully so that you will benefit from all the features as soon as you start using the amplifier.
The built-in quality of a Fender
®
amplifier is the result of
over four decades of dedication in the combined skills of
research and development by our engineers and musicians.
That is why we proudly say...FENDER
®
, The Sound That
Creates Legends.
WARNING: TO REDUCE THE RISK OF FIRE OR SHOCK
HAZARD, DO NOT EXPOSE AMPLIFIER TO RAIN OR
MOISTURE.

INPUT 1- A high impedance, high sensitivity plug-in
A.
connection for instruments.
INPUT 2- Plug-in connection for instruments. This
B.
input exhibits a lower input impedance and sensitivity
than INPUT 1 (Item A) and is useful with active preamp
guitars, and will provide a darker tone with passive
guitars. Both inputs are identical when used simultaneously.
VOLUME- Adjusts the overall loudness of the Normal
C.
Channel.
NORMAL CHANNEL INDICATOR- This LED is illumi-
D.
nated when the Normal Channel is active.
TREBLE- Adjusts the amount of boost (accentuation) or
E.
cut (attenuation) in the high frequency range of the
Normal Channel.
MID- Adjusts the amount of boost or cut in the mid fre-
F.
quency range of the Normal Channel.
BASS- Adjusts the amount of boost or cut in the low
G.
frequency range of the Normal Channel.
REVERB- Adjusts the overall amount of reverberated
H.
signal mixed with the original dry signal for the
Normal Channel.
GAIN- Adjusts the amount of preamp amplification in
I.
the Drive Channel. Cleaner sound is achieved at
lower gain settings; high gain settings will produce
more sustain and distortion. This control works in conjunction with the DRIVE VOLUME control (Item L) to set
the overall loudness at the output while the Drive
Channel is active.
MID BOOST- Activates a special pre-emphasis filter
J.
that accentuates mid range frequencies. This boost
occurs pre distortion in the Drive Channel and will further modify the distortion characteristic.
PRESENCE- Adjusts the amount of boost or cut in the
K.
upper high frequency range of the Drive Channel.
This control occurs post preamp distortion and is useful
in adjusting the distortion characteristic from brash, to
smooth.
VOLUME- Adjusts the overall loudness of the Drive
L.
Channel.
DRIVE CHANNEL INDICATOR- This LED is illuminated
M.
when the Drive Channel is active.
TREBLE- Adjusts the amount of boost or cut in the high
N.
frequency range of the Drive Channel.
MID- Adjusts the amount of boost or cut in the mid fre-
O.
quency range of the Drive Channel.
BASS- Adjusts the amount of boost or cut in the low
P.
frequency range of the Drive Channel.
DRIVE SELECT- Activates the Drive Channel. NOTE:
Q.
This switch disables the Channel Select Footswitch and
the Normal Channel controls.
REVERB- Adjusts the overall amount of reverberated
R.
signal mixed with the original dry signal for the Drive
Channel.
RATE- Adjusts the sweep rate of the chorus generating
S.
circuitry. A lower number corresponds to a slower
rate of sweep.
T.
SELECT- Activates the stereo CHORUS mode for both
the Normal and Drive channels. NOTE: This switch
disables the Chorus Select Footswitch.

DEPTH- Adjusts the intensity of the chorus effect. A
U.
QT
lower setting will introduce a subtle yet distinct effect,
whereas a higher setting will create a more dramatic
effect. With both the RATE (Item S) and DEPTH controls
set midway or higher, a variety of vibrato/tremolo
type effects can be achieved.
CHORUS INDICATOR- This LED is illuminated when the
V.
stereo chorus is active. The color of the LED is modulated red and green by the chorus sweep LFO to give
a visual indication of the sweep rate.
FOOTSWITCH- Plug-in connection for remote
W.
footswitch to switch between the Normal and Drive
channels and to activate the Stereo Chorus mode. For
proper operation of the footswitch, both DRIVE SELECT
(item Q) and CHORUS SELECT (Item T) switches should
be out. NOTE: Any good quality patch cord will work
with the remote footswitch; however, a speaker grade
cord is preferable to a coax guitar cord when it is
available.
MONO FX SEND- This jack provides an unbalanced
X.
mono output signal from the preamp at a point before
the internal CHORUS circuits. This output can be used
in conjunction with the MONO FX RETURN (Item Y) as
a patch point for mono effects devices. (SEE EFFECTS
LOOP CONNECTION DIAGRAMS.) The MONO FX
SEND can also be used to feed recording and sound
reinforcement mixers a dry signal. (For a signal with
internal CHORUS, use the STEREO FX SEND (Item Z)
jack.) Additionally this output can be used to drive
another ULTIMATE CHORUS as a slave amp. This is
done by connecting a standard guitar cord from the
MONO FX SEND jack of the master amplifier to the
MONO FX RETURN jack of the slave.
Y.
MONO FX RETURN- This unbalanced jack inputs sig-
nal to the stereo chorus generating circuitry, which
drives the stereo power amp section. It automatically
disconnects the preamp and reverb circuitry when
used. This is useful when using the MONO FX option
or when using the ULTIMATE CHORUS as a slave
amplifier for a mono signal source. The CHORUS is
active in the slave so that a stereo image will be generated if it is used.
Z.
STEREO FX SEND- This jack provides an unbalanced
stereo output from the preamp, reverb and chorus circuits of the ULTIMATE CHORUS. This output can be
used in conjunction with the STEREO FX RETURN (Item
AA) as a patch point for stereo effects devices. (SEE
EFFECTS LOOP CONNECTION DIAGRAMS.) The
Stereo Effects Loop jacks are standard 1/4 inch TipRing-Sleeve types, with the left channel signal on the
tip and the right channel signal on the ring. This send
can also be used to feed a stereo signal to two channels of a recording or sound reinforcement mixer.
Additionally this output can be used to drive another
ULTIMATE CHORUS as a slave amp. This is done by
connecting a shielded stereo cord from the STEREO FX
SEND jack of the master amplifier to the STEREO FX
RETURN jack of the slave.
AA.
STEREO FX RETURN- This stereo jack inputs signal
directly to the left and right power amps. It automatically disconnects the preamp, reverb and chorus circuitry when used. This is useful when using the ULTIMATE CHORUS as a slave amplifier for a stereo signal
source.
BB.
POWER SWITCH- Turns AC power ON and OFF.
When the switch is OFF the amplifier is completely
shut down.
