M. EXTERNAL SPEAKER OUTPUT (500/200 COMBO
ONLY): Connect 8Ω (minimum impedance) speaker
cabinet here. Power rating of external cabinet should
meet or exceed rating listed on the amplier.
N. HORN SWITCH (500/200 COMBO ONLY): Press to "ON"
position to turn horn on. Press to "OFF" position to turn
horn o. Horn adds high-frequency crispness and sparkle
for more modern tones well suited to slap-style playing.
O. EFFECTS LOOP (500, 200 AND 100 ONLY): Connect SEND to
input of outboard eects devices (delay, chorus, etc.) and output of
eects devices to RETURN. Using EFFECTS LOOP
(instead of between your bass and the INPUT)
reduces amount of noise and tone degradation
caused by eects pedals.
P. AUX IN: Connect external audio device here. Amp controls
do not aect this input. Adjust volume/tone of aux signal at
its source.
Q. HEADPHONES: Connect headphones here (32Ω minimum
impedance). Speaker output is automatically muted.
R. LINE OUT: Balanced output for connection to external
devices such as PA systems and recording consoles.
Level and tone of LINE OUT signal are aected by all
preamp controls, including GAIN. Engaging GROUND
LIFT button may eliminate hum or buzz resulting from
connection to improperly grounded equipment.
S. FOOTSWITCH: For remote switching of OVERDRIVE
circuit; see Optional Footswitches section below.

Connect a footswitch to the amplier 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),
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 footswitch.
VINTAGE FOOTSWITCH (PN 0994054000): Chrome
single-button on/o footswitch.
LED FOOTSWITCH (PN 0994052000): Contemporary
single-button on/o footswitch with LED indicator. NOTE:
For footswitch LED to operate properly, OVERDRIVE eect
must be o before connecting this footswitch.
OPTIONAL FOOTSWITCHES
REAR PANEL (CONT'D.)
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.
