Fender Bassman 100T Owner's Manual page 6

Thank you for choosing the Fender® Bassman® 100T, 100
watt tube bass head. This amplifier was designed to provide
the ultimate bass playing experience, with two channels
(Vintage/Overdrive), classic good looks and modern technol-
ogy designed to maximize classic technology.
The Vintage channel offers a classic Fender passive tone
stack. This "cut-only" interactive circuit provides a distinctly
old-school caramel-like thickness to the notes. The Overdrive
channel has an active tone stack, very quick and responsive,
with the ability to get incredibly aggressive. Foot switch
between these on stage for an instant tone make-over.

INPUTS

VOLUME BASS
A. INPUTS — Plug your bass into the input that sounds
the best to you! Input "2" is a lower sensitivity input (–6dB)
and provides cleaner response with high-output or active
instruments. If both inputs are used simultaneously, their input
sensitivities become identical, both –6dB.
B. VOLUME — Adjusts the volume level of the Vintage channel.
C. BASS / MID / TREBLE — Classic, cut-only (passive) tone stack.
Pull the BASS knob out for emphasis in the low-frequency range
(DEEP). Pull the TREBLE knob out for an increase in the high-
frequency range (BRIGHT).
D. CHANNEL SELECT — Selects the active channel as indicated by
the green and red LEDs. When the VINTAGE channel is selected
(switch in the down position, green LED), the knobs on the
left {B–C} are active. When the OVERDRIVE channel is selected
(switch in the up position, red LED), the knobs on the right {E–J}
are active.
♫
The included Footswitch can also be used to select channels. See
FOOTSWITCH {U} on next page.
E. GAIN — Adjusts the amount of preamp tube distortion in the
Overdrive channel.
F. BLEND — Controls the amount of distorted signal (set by GAIN)
to be blended with the clean bass signal. Lower settings can
maintain a cleaner tone, with some added grit. Higher settings
will produce more distorted tones and add sustain. Set to "1" for
clean tube bass signal only.
NOTE: The TUNER OUT {V}, POWER AMP IN and PRE AMP OUT {W} jacks are balanced TRS (Tip/Ring/Sleeve) type
jacks, with tip=positive (+), ring=negative (–) and sleeve=ground (GND). While standard shielded TS (Tip/Sleeve)
"mono" guitar cables can certainly be used, the use of "stereo" TRS cables may improve signal-to-noise ratio and
reduce hum due to line noise.

Fender Automatic Bias removes "tube anxiety" by constantly
monitoring and re-biasing the tubes for perfect performance
and alerting when service is required. Silent recording is easy.
Simply set the Output Power switch to Silent and capture
the Pre AND Power amp tone out of the XLR output without
waking the neighbors!
The Bassman 100T will provide a life time of thick, natural,
balanced tone that sits fat in your live or studio mix.
Enjoy!

VOLUME BASS FREQ MID LEVEL
G. VOLUME — Adjusts the volume level of the Overdrive channel.
Use together with the GAIN knob {E} to set the overall loudness
of the Overdrive channel.
H. BASS — Adjusts the amount of low-frequency boost or cut
(±15dB) of the Overdrive channel. Set this knob to the center
detent position for flat bass response. Pull this knob out for low-
frequency emphasis (DEEP).
I. MID FREQ / MID LEVEL — Use the FREQ knob to set the
frequency at which the LEVEL knob adjusts the middle-frequency
boost or cut (±18dB) of the Overdrive channel. Set the LEVEL
knob to the center detent position for flat mid response.
♫
It is easiest to adjust MID when the LEVEL control is at its
maximum or minimum, so that the effect of the FREQ knob is
more easily heard. Once the proper FREQ setting is found, adjust
the LEVEL knob to the desired setting.
J. TREBLE — Adjusts the amount of high-frequency boost or cut
(±15dB) of the Overdrive channel. Set this knob to the center
detent position for flat treble response. Pull this knob out for a
high-frequency boost (BRIGHT).
K. MASTER — Adjusts the overall volume of the amplifier. Pull this
knob out to mute all outputs from the amp except the TUNER
output, useful for silent instrument tuning.
L. POWER INDICATOR — Illuminates when power to the unit is
switched on.
