Thanks for buying a Fender Rumble 800 bass amplifier. Fender bass
amplifiers are legendary for providing thick, natural and balanced
tone that sits fat in your live or studio mix. Rumble amps are
designed by and for bass players, and we take great pride in putting
full-featured, easy-to-operate amps of the highest quality in the
hands of working and aspiring musicians everywhere.
A.
INPUT: Plug passive or active bass in here. If bass is too hot and
causes unwanted distortion, turn GAIN control down.
B.
GAIN: Adjusts incoming signal level (0dB to +20dB), optimizing
preamp signal level for a variety of basses. Setting this control to
noon is a good starting point; GAIN setting also affects level of
distortion/compression when VINTAGE and/or OVERDRIVE are
selected.
C.
BRIGHT, CONTOUR AND VINTAGE: BRIGHT adds presence
and shimmer in the upper frequencies. CONTOUR is a mid-
frequency cut, combined with low- and high-frequency boosts
that offer a fat pleasing tone, useful for slap and low-volume
playing, or in combination with OVERDRIVE (E). VINTAGE creates
a dark tone rich with harmonics and some natural compression.
D.
DRIVE: Controls amount of harmonically rich preamp distortion
when OVERDRIVE (E) is engaged.
E.
OVERDRIVE: Activates overdrive circuit and controls; light
indicates use.
F.
LEVEL: Controls overdrive volume when OVERDRIVE (E) is
engaged. Use to balance volume levels between clean and
overdrive tones.

higher or playing more aggressively, modified Fender Delta-
Comp™ limiter circuitry delivers more tube-like response to
speakers with greater compression, harmonics and sustain.
OUTPUT SWITCH: Set switch to FULL for normal maximum
power (800W or 400W internal). Set to LOW to get the same tone
at reduced output/volume levels (200W or 100W internal).
POWER/STATUS INDICATOR: Illuminates solid red when
power is on; flashes amber when maximum output power is
produced for short periods (normal for uncompressed bass
guitar). Illuminates solid amber when amp enters "protect
mode" (see Thermal Performance and Protection) and briefly
during power on/off.
