Congratulations on your purchase of a Bassman
amplifier. Among its many features:
•300 Watts of output power into 2Ω, 4Ω, or 8Ω (selectable)
•Two channels for both clean and distortion outputs
•Vacuum tube pre-amplifier and power-amplifier design
•10-band graphic equalizer and split band compressor
A. INPUT - Plug your electric bass guitar in here.
B. -6 dB PAD - Sensitivity / gain switch for the input signal.
Button IN provides a -6dB attenuation useful for electric
bass guitars with high output levels, such as basses with
active pickups.
C. CH 1 VOLUME - Adjusts the loudness of channel 1.
D. CH 1 LED - Illuminates when channel 1 is active.
E. CH 2 GAIN - Adjusts the channel 2 gain/distortion level.
F. CH 1 / 2 MIX LED - Illuminates when the ch select
button is IN indicating the Ch. 1 / Ch. 2 mix is active.
G. CH 2 VOLUME - Adjusts the loudness of channel 2.
H. CH SELECT - When this button is IN, both channel 1
and channel 2 are active.
conjunction with the CH. 1 / 2 MIX knob.
footswitch overrides this switch.
I. CH 1 / 2 MIX - Mixes the channel 1 and channel 2 output
levels. At "1", only channel 1 is in the output mix. At "10",
only channel 2 is in the output mix. By rotating the knob, an
optimum mix of both channels may be obtained.
J. LOW - Adjusts the low frequency level of both channels.
In its center notched position, the equalization is "flat" with
no modification.
K. HIGH - Adjusts the high frequency level of both
channels. In its center notched position, the equalization is
"flat" with no modification.
L. DEEP - Low frequency boost when this button is IN.
M. BRIGHT - High frequency boost when this button is IN.
N. MID NOTCH - Reduces the mid-frequency tones, giving
the amp a "punchy" sound when this button is IN.
O. GRAPHIC - Activates the graphic equalizer when this
button is IN. Using the footswitch overrides this switch.
P. LINE OUT - This switch is used in conjunction with the
line out jacks on the rear of the 300. When this button is
IN, the signal sent from the 300 includes frequency
shaping, channel switching and compression. The line out
signal does NOT include any effects which may have been
added via the effects loop. When the button is OUT the
signal is passed through the 300 without any tone shaping
or enhancement.

•Footswitch with equalizer, compressor and channel
switching
•Low-noise differential effects loop
•Tuner out jack for pass-through tuning
•XLR and 1/4 inch line out jacks and a pass-through jack for
output to another amplifier or to a mixing console
•All steel chassis for enduring reliability
Q. GRAPHIC EQ - The 10 band-pass / band-reject filters
are spaced at octave intervals. Move each slider up to
boost or down to cut the level of each indicated frequency.
The EQ Trim slider will boost or cut the signal level through
the graphic EQ with the centered notched position having
no affect on the level.
R. GRAPHIC EQ LED - Illuminates when the graphic EQ is
active.
S. LOW COMP - Adjusts the compression ratio below
400Hz. Clockwise rotation increases the compression
ratio.
T. COMP - When this button is IN the compressors are
active. Using the footswitch overrides this switch.
U. HIGH COMP - Adjusts the compression ratio above
400Hz. Clockwise rotation increases the compression
ratio.
V. COMP LED - Illuminates when the compressor is active.
W. COMP EQ BAL - Mixes the low and high compressor
outputs. When the knob is at "1", only the low compressor
is in the output mix. When the knob is at "10", only the high
compressor is in the output mix. By rotating the knob, an
optimum mix of both compressors can be obtained.
X. INPUT LEVEL LED - Always indicates signal level.
Glows green above the compressor threshold. Glows red
above the pre-amp clipping/distortion threshold.
Y. COMP GAIN TRIM - This knob adjusts gain to
compensate for any level imbalance when the compression
circuitry has been engaged.
Z. TUNER ONLY - While this button is IN all outputs from
the amplifier are muted except to the tuner jack. Useful for
quick and silent bass tuning.
AA. MASTER VOLUME - Adjusts the overall volume level
of the 300 in conjunction with the gain controls of the active
channel(s).
BB. POWER LED - Illuminates when the 300 is ON and
receiving power.
CC. STANDBY - When the power switch and this switch
are ON, your 300 is ready to perform.
position, power is supplied only to the tube filaments and
sound will NOT come out of the amp. Using the standby
switch during short breaks eliminates tube warm-up time
and will increase tube life.
