Rumble bass amplifiers are equipped with Fender’s Delta-
Comp limiter to minimize power amp distortion and increase
sustain. Setting the VOLUME control to higher settings
or playing aggressively with hotter basses may result in a
heavily compressed sound with increased sustain. Using the
–6dB switch or setting the VOLUME control lower will provide
a less compressed sound with more dynamic range and
increased touch-sensitivity.
Rumble bass amplifiers are equipped with variable speed fan
cooling and thermal shutdown protection. The fan will start
at a low speed and increase as you play harder. Leave at least
6 inches of clearance between the vents on your amplifier
and other objects. If the amplifier vents are blocked, or it
is used in an extremely hot environment, it may overheat
and shut down causing a temporary mute of the speaker
while the power LED indicator remains on. Under the most
extreme operating conditions it may be possible for the
thermal shutdown to disrupt the amplifier power supply
and the speaker will mute and the power LED indicator will
turn off. If any shutdown (speaker muting) occurs, leave the
power switch ON (to keep the fan running), and allow the
amplifier several minutes to cool down. The amplifier will
automatically resume operation when it has returned to a
safe operating temperature.
