M. EXTERNAL SPEAKER OUTPUT (500/200 COMBO
ONLY): Connect an 8Ω (minimum impedance) speaker
cabinet here. The power rating of the external cabinet
should meet or exceed the rating listed on the
amplifier.
N. HORN SWITCH (500/200 COMBO ONLY): Press to the
"ON" position to turn the horn on. Press to the "OFF"
position to turn the horn off. The horn will add high-
frequency crispness and sparkle for more modern tones
that are well suited for slap-style funk.
O. EFFECTS LOOP (500, 200 AND 100 ONLY): Connect the SEND to
the input of outboard effects devices (delay, chorus, etc.) and the
output of the effects devices to the RETURN.
Placing effects in the EFFECTS LOOP (instead of
between your bass and the INPUT) will reduce the
amount of noise and tone degradation caused by
the effects pedals.
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 it is used in an extremely hot envi-
ronment, it may overheat and shut down causing a temporary mute of
the speaker while the power LED indicator remains on. Under the most
RUMBLE HEAD AMPLIFIERS WITH RUMBLE SPEAKER ENCLOSURES
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.
Connect a footswitch to the amplifier 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=off),
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.

down 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 operat-
ing temperature.
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.
