1&2) EFFECTS LOOP: Basically an
insert patch point. When an external effect
is patched into the series send and return
jacks, the path is interrupted and 100%
of the signal is routed through the effect.
This puts some special demands on the
effects unit itself. First, it must be essen-
tially transparent meaning it should not
mess with your tone. The input and output
levels must be properly set for maximum
headroom and lowest noise. Proper setting
of the levels can be achieved using the fol-
lowing method. a) Set you amp GAIN and
VOLUME controls for normal playing lev-
els. Connect a high quality shielded cable
from the send jack to the effect input. b)
Adjust the effects unit input level control so
that the indicator ‘just peaks“ when playing
your most aggressive licks. c) Now connect
another high quality shielded cable from
the effect output to the return jack. Adjust
the effect unit output level to match the vol-
ume you heard before connecting the return
cable. You can check this by pulling the
cable in/out of the return jack while playing
to verify there is not substantial volume dif-
ference. This is called “unity gain”. A cool
techie term for “you get out what you put
in”. If your effects unit does not have level
adjustments, it can be assumed you will
get unity gain when plugged in. SPECIAL
NOTE: Depending on how loud you play,
the level at the loop may be higher than
normal guitar levels. Though most pedal
and rack type effects may work, some can
be overloaded. You will know an effects
gadget is no made for higher levels if, when
you plug the effect into the loop, you notice
distortion and/or a loss of volume. Most
modern effects (including many pedals) can
work just fine in an effects loop. We have
gone to great lengths to make the Tweaker
loop compatible with as many different ef-
fects units as possible.

4) WARNINGS AND CAUTIONS
5) IMPEDANCE SWITCH: Set this
switch to match the impedance of the
speakers. The correct setting for the Tweak-
er 112 combo is 16 ohms. The proper set-
ting for the Tweaker 112 extension cabinet
is also 16 ohms. Otherwise, always match
the setting of the tweaker switch to match
the impedance of whatever speakers you
are using.
6) MAIN SPEAKER OUTPUT: Labeled
“USE FIRST” because you must.........
use this jack first. There is a special circuit
inside the Tweaker that helps protect the
amplifier from damage in case you have
a bad speaker cable of forget to plug the
speaker in. as we all know, NEVER operate
any tube amp without a proper speaker load
connected.
7) EXTENSION SPEAKER: Used for
connecting a second speaker cabinet. Since
the MAIN speaker output is labeled “USE
FIRST”, you can assume the EXTENSION
speaker output could be labeled “USE
SECOND”.
8) 250mA FAST-BLO FUSE: This fuse
is there to protect the internal amplifier
circuits against damage that can be caused
by a shorted output tube. In case of a power
tube failure, this fuse will open and there
will be no sound. If the amp appears to
be “lighting up” normally but there is no
output, check this fuse. If the fuse is blown
(open), this indicates that one of the 6V6
power tubes had likely failed and must be
replaced. Use the following procedure to
determine which tube is shorted. a) Turn
off the POWER and STANDBY switches.
b) Allow the tubes to cool and remove
the two 6V6 power tubes. c) Install a new
250mAFast-Blo fuse. Turn on the POWER
and STANDBY switches. If the fuse does
not blow, one of the 6v6 tubes is defi-
nitely shorted. It is recommended the tubes
always be replaced in matched pairs for
best performance. Simply install the new
pair and you should be “good to go”. The
Tweaker amp utilizes a circuit design called
“cathode bias”. This allows you to simply
plug in the power tubes without regard for
any bias or other adjustments. Basically
PLUG and PLAY.
9) AC VOLTAGE SELECTOR: Makes
the Tweaker compatible with the line volt-
age in any country. Proper setting of the
switch is absolutely critical. Be sure the
switch position matches the line voltage
in your country. Severe damage will result
improperly setting this switch and will void
your warranty, as well as destroy your amp.
10) Ac iNLET AND FUSE: connect a
universal IEC type power cord. Be sure the
proper value fuse is installed as indicated
on the rear panel.
