Introduction
The Fender TWIN™ is the next step up in the evolution of High
Performance instrument amplification. The new TWIN is a direct
descendent of classic tube amps such as the Fender Twin Reverb®,
and 410 Bassman®, which have shaped today’s world of guitar
amps.
The features of the new Fender TWIN provide flexibility rarely found
in tube amplifiers. Channel One is the traditional Fender design
which offers the vintage sound as well as contemporary sounds with
the use of switch-selectable Gain and Master Volume controls.
Channel Two is like owning a second, modern hot-rodded amp with
more soaring gain than previously found in a Fender tube amp. The
CLASSIC Fender tube reverb sound is there too and is switch assignable to Channel One, Channel Two, or both. Finally, a master PRESENCE control allows you to “dial-in” just the right amount of highend sparkle.
design which has become the industry standard as a result of its time
worn reputation for reliability and good sound; however, this amplifier goes further than its clones. In addition to a HIGH/LOW
POWER switch, that you can hear, the TWIN also features external
bias and balance adjustment capability. The four 6L6WGC/5881
output tubes can be set up by anyone with a digital voltmeter without
removing the chassis. This means that you can re-bias every time
you re-tube and can check bias and balance over the life of the
tubes. With the price of tubes today you can’t afford not to have
them set up right every time. In addition to being able to drive a
wide range of speaker combinations from the three speaker output
jacks, switch selectable to 4, 8, or 16 ohms, the BALANCED LINE
OUTPUT will drive any 600 ohm line input. This is a transformer
coupled, truly balanced, floating ground output which is particularly
useful for driving slave power amps or, with the proper equalization,
as a send to a mixing console for recording or sound reinforcement.
Special effects will interface to the Effects Loop easily and with no
guesswork on levels. Simply set the three position LEVEL SELECT
switch to match up to the latest rack-mount digital processor or your
old favorite battery powered effect pedals. The effects MIX control is
used for blending the effect (wet) sound with the normal (dry) guitar
sound. Depending on the effects device used, the effects MIX control, when set to “10”, will produce the “wet” sound only. A three
position switch is provided for assigning the Effects Loop to Channel
A, Channel B, or both. In addition, the PREAMP OUT & POWER
AMP IN jacks can be used as a second effects loop, or as Send and
Return points while slaving amps together. The possibilities are endless (e.g., by inserting a Chorus pedal between the PREAMP OUT of
an amp and the POWER AMP IN of another, a true stereo image
effect can be achieved).
The power amplifier section of the TWIN is a 100 Watt Fender
The Fender TWIN features two Fender Special Design 12” speakers
which have been specifically tailored to reliably produce the legendary Twin Reverb sound.
The selection of a Fender amplifier will reward you with years of
quality music in a wide range of controlled sounds. This manual is
designed to familiarize you with the equipment and to acquaint you
with its many fine features. Please read it carefully so that you will
benefit from the many 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.
Twin Amp Sound Settings
Note: These settings are suggested starting points. Your settings may vary due to your guitar, venue, or most importantly...personal taste!
Twin Front Panel Functions (Fig.1)
M. TREBLE — Adjusts the amount of boost or cut in the high frequency range of Channel Two.
A. INPUT 1 — A high impedance, high sensitivity plug-in connection
for instruments.
B. INPUT 2 — A plug-in connection for instruments. This input
exhibits less input impedance and sensitivity than INPUT 1, making it
useful for guitars that have active pickups. This input will provide a
darker tone if used with guitars that have passive pickups.
Note: INPUT 1 and INPUT 2 are inputs for both Channel One and
Channel Two.
C. VOLUME — Adjusts the overall volume of the Channel One Clean
Sound.
D. PULL BRIGHT — This pull switch on the Clean Sound VOLUME
control (item C) boosts the highs. This has the sonic effect of adding
high end “sparkle” (to the Clean Sound only).
E. GAIN — Adjusts the gain for the Channel One Vintage Drive
Sound. Lower settings provide an “on-the-edge” clean sound, while
higher settings provide gradual compression, like a “cranked” vintage amp, but at controllable volumes. This control works in conjunction with the Channel One Vintage Drive Sound VOLUME control
(item J) to set the overall volume of the Channel One Vintage Drive
Sound.
F. TREBLE — Adjusts the amount of boost or cut in the high frequency
range of Channel One.
G. BASS — Adjusts the amount of boost or cut in the low frequency
range of Channel One.
N. BASS — Adjusts the amount of boost or cut in the low frequency
range of Channel Two.
O. MID — Adjusts the amount of boost or cut in the middle frequency range of Channel Two.
P. CHANNEL TWO INDICATOR — When this red LED is lit, Channel
Two is selected, and the Channel Two GAIN (item L) and VOLUME
(item Q) controls are active.
Q. VOLUME — Adjusts the overall volume of Channel Two. As this
control is rotated clockwise from the “1” position, the volume comes
up slowly at first for additional control at lower listening levels; but
near mid volume settings, the volume comes up faster for perfomance
levels.
R. PULL CHANNEL SELECT — When this pull switch on the Channel
Two VOLUME control (item Q) is in the “in” position, Channel One is
selected. When it is in the “out” position, Channel Two is selected.
This pull switch is overridden when the footswitch is connected.
S. MIX — Adjusts the amount of audible “wet” (processed) signal
when the variable level effects loop (located on the back panel) is
used. When the MIX control is in the full counter-clockwise position
(“1”), the “wet” signal will not be audible. When the MIX control is
in the full clockwise position (“10”), only the “wet” signal will be
heard (depending on the type of effect used). When nothing is
plugged into the EFFECTS RETURN jack (located on the rear panel),
the MIX control will have no effect on the sound. Also see the
“EFFECTS SELECT” switch in the Twin Rear Panel Functions section of
this manual.
F. MID — Adjusts the amount of boost or cut in the middle frequency
range of Channel One.
I. VINTAGE DRIVE INDICATOR — When lit, this yellow LED indicates
that the Channel One Vintage Drive Sound is selected, and that the
Channel One Vintage Drive Sound GAIN (item E) and VOLUME
(item J) controls are active.
J. VOLUME — Adjusts the overall volume of the Channel One
Vintage Drive Sound.
K. PULL GAIN SELECT — When this pull switch on the Vintage Drive
Sound VOLUME control (item J) is in the “in” position, the Channel
One Clean Sound is selected and the Clean Sound VOLUME control
(item C) is active; when in the “out” position, the Vintage Drive
Sound is selected, and the Channel One Vintage Drive Sound GAIN
(item E) and VOLUME (item J) controls are active. This pull switch is
overridden when the footswitch is connected.
L. GAIN — Adjusts the amount of gain in Channel Two. Lower settings provide gradual compression, while higher settings provide
more sustain... lots more sustain.
T. REVERB — Adjusts the amount of reverb present in Channel One
and Channel Two. When the footswitch is connected, the reverb can
be turned on and off remotely. Also see the “REVERB SELECT
SWITCH” in the “Twin Amp Rear Panel Functions” section of this
manual.
U. PRESENCE — This is a true vintage-style PRESENCE control that
affects the way the power amplifier responds to upper high frequencies. As the control is turned clockwise, the power amplifier (in interaction with the speaker load) enhances upper highs, giving the
Twin’s overall sound a “sparkling” quality.
V. PILOT LAMP — When this lamp is illuminated, the amplifier is
receiving power. Should the lamp burn out, turn off the amplifier and
unplug it from its power source, unscrew the red jewel, and replace
the lamp with type T47 light bulb.

A. FUSE — The fuse is in the AC supply of the amplifier and will pro-
tect the amplifier and the operator in the event of an electrical fault.
