Connect a footswitch to the ampli

er to remotely enable OVERDRIVE.
The three Fender footswitches at right are compatible with Rumble
(although any generic single-button latching-type footswitch will work).
Fender recommends the LED FOOTSWITCH (PN 0994052000) for best
performance. Contact your local Fender dealer to purchase the Fender
footswitch of your choice.
NOTE:
When a footswitch is connected, the control panel OVERDRIVE
button will still work, but its position may become reversed (i.e., in=o
ff
),
depending on footswitch status. The OVERDRIVE indicator LED on the
control panel will
always
be correct, but the LED in the footswitch may
be incorrect. When using a footswitch with an LED, keep the control
panel OVERDRIVE switch in the
out
position to have the correct status
displayed on the footswitch LED.
ECONOMY FOOTSWITCH (PN 0994049000):
Basic black
single-button on/o

Rumble amp heads are lightweight and compact, which makes trans-
port and setup easy. When placed atop a non-matching speaker enclo-
sure, however, they become subject to the extreme vibrations they're
capable of producing at high volume. Matching Rumble speaker enclo-
sures feature a magnetic locking system to properly secure Rumble
amp heads in place during normal operation. Simply place the Rumble
amp head into the foot cups atop the Rumble speaker enclosure to lock
it in place.
NOTE:
The magnetic locking system should
not
be used to secure a
Rumble amp head during transport; first detaching the Rumble amp
head from the Rumble speaker enclosure is recommended to avoid
potential damage. Please use caution when using a Rumble amp head
atop any other non-matching speaker enclosure.
RUMBLE AMP HEADS WITH RUMBLE SPEAKER ENCLOSURES
Rumble 500/200 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 if it is used in an extremely hot envi-
ronment, it may overheat and shut down, causing a temporary muting
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, causing the speaker to
mute and the power LED indicator to turn off. If any shutdown (speaker
muting) occurs, leave the power switch ON (to keep the fan running),
and give the amplifier several minutes to cool down. The amplifier will
automatically resume operation when it has returned to a safe operat-
ing temperature.
