A.
LINE CORD -
Your amplifier is equipped with a 3-prong, grounding type supply cord designed to reduce the possibility
of shock due to electrical fault. Be sure to connect the cord to a grounded receptacle. DO NOT ALTER THE AC PLUG!
B. POWER SWITCH -
Turns the AC POWER on and off. When this switch is in the OFF position the amplifier is completely
shut down.
C.
FUSE -
The fuse, located in the AC supply of the amplifier, helps protect the amplifier in the event of an electrical fault or
tube failure. If the fuse blows, replace it with one of the same type and rating.
NEVER
use a fuse of a higher current rating.
Doing so could severely damage the unit and present a serious safety hazard. If the amplifier repeatedly blows fuses, take it
to an authorized Fender warranty service center.
D.
STANDBY SWITCH -
Toggles between the operate and stand-by mode. When the switch is in the stand-by mode, no
sound will be heard. Power, however, is still supplied to the tube filaments to keep them warmed and the unit ready to play.
Using this switch during short breaks will help increase tube life. A good rule of thumb is wait at least 50 seconds after the
power switch is on, before turning on the standby switch.
E. RECTIFIER/BIAS SWITCH -
Allows for the selection of Rectifier sounds and bias classes to best suit your playing style.
(Experiment until you find a preferred setting).
The Class A/TUBE setting at low volume sounds a lot like the Class AB2/Solid
State setting at high volume
.
F. IMPEDANCE SWITCH- (Head only)
Labeled 4, 8 and 16. This switch serves to set the output impedance of the amplifi-
er to best match the speaker impedance for maximum power and tube life.
G.
SPEAKER (Combo), SPEAKER 1 (Head) -
Input connection for speakers. This jack is the primary connection for speakers.
H.
EXTERNAL SPEAKER (Combo), SPEAKER 2 (Head) -
Input connection for an external speaker. This jack is ONLY
used in conjunction with the main SPEAKER JACK. If the EXTERNAL SPEAKER JACK is used without a cord / speaker
plugged into the main SPEAKER JACK, there will be no sound. Using this jack on the Combo automatically switches the
amplifier impedance to 8
Ω
.
I.
FOOTSWITCH JACK -
Input connection for the footswitch. The footswitch allows remote switching from CHANNEL A
(normal) to CHANNEL B (drive), as well as, on and off for the REVERB on the Combo unit ONLY. The Head amplifier
footswitch has a single button ONLY.
J. EFFECTS RETURN -
Input jack or “Return” from effects device(s). Inserting a cord here automatically disconnects the
internal connection from the pre-amp and power connection.
K.
EFFECTS SEND -
Output jack for “Send” to effects device(s). This jack can also be used as a line out.
L.
CHANNEL SWITCH -
Allows the remote switching from CHANNEL A (normal) to CHANNEL B (drive).
M. REVERB SWITCH (Combo only) -
Allows the remote switching of the reverb effect.
