REBEL-30 OVERVIEW
Rebel: One who opposes or disobeys authority or control.
Rebel-30: The Rebel-30 head is an extention of the award-winning
Rebel-20 head, adding a whole new level of flexibility and tone-shaping power. These 30-watt all-tube, 2-channel heads feature Egnater’s
unique TUBE MIX knob, giving you access to an incredible variety of
tones, from American to British and all points in between. Channel 1
delivers rich cleans with controls for volume, treble and bass. Channel
2 dishes out powerful, touch-responsive overdrive with treble, middle
and bass EQ, as well as a wide-range gain knob that takes you from
growl to scream. Both channels feature Egnater’s signature BRIGHT
and TIGHT switches and each channel has its own WATTS knob so you
can access both low-wattage crunch and serious clean headroom, or any
combination you choose.
The REBEL-30’s specially designed and easily accessible back panel
holds more welcome surprises, such as independent REVERB controls
for each channel and a tone-preserving series effects loop. A speakeremulated line out lets you go directly to the board live or in the studio.
Set the standby switch to ‘Silent Record’ for great direct-recorded tones
that spare both your ears and your neighbors. And the easy-access chassis makes swapping tubes quick and painless. The REBEL-30 is also
available as a 1x12” combo with the same dimensions as the REBEL112x cab and as a 2x12” combo. Both include a dual-function footswitch for channel selection and reverb on/off.

1) GUITAR INPUT: Plug your guitar in
here using a high quality, shielded instrument cable.
2) CHANNEL SELECT: A pushbutton
switch to select CHANNEL 1 or CHANNEL 2. NOTE: This switch is disabled
when using the footswitch.
3) CHANNEL 1 LED: ON indicates
CHANNEL 1 is active.
4) CHANNEL 1 TIGHT: Same effect as
CHANNEL 2. The tight (up) position cuts
out the deep bass to better balance the tone
with different guitars. TIGHT will also
help clean up the low end if you are cranking the VOLUME knob up and overdriving the channel.
5) CHANNEL 1 BRIGHT: Same as
CHANNEL 2. Adds high end sparkle.
Experiment with different combinations
of the TREBLE knob and the BRIGHT
switch.
6) CHANNEL 1 VOLUME: Sets the
overall loudness of CHANNEL 1. Remember what we said earlier about the interaction between the VOLUME control and
the WATTS knob.
7 & 8) TONE CONTROLS FOR
CHANNEL 1: Once again, the familiar
passive tone control circuits from the classic amps we all love. This channel can be
1
6
2
7
very warm and friendly, like a great old
vintage combo, or crystal clear and glassy
for a pristine clean sound. Just turn the
knobs to find your tone, it’s in there.
9) CHANNEL 2 TIGHT: This switch
is really useful for tightening up the low
end, especially when using a lot of gain.
It works by cutting the deep bass at the
beginning of the high gain preamp. Setting the TIGHT switch up will result on a
clearer, less muddy distortion.
10) CHANNEL 2 LED: ON indicates
CHANNEL 2 is active.
11) CHANNEL 2 BRIGHT: Just as you
expect, the up (BRIGHT) setting of the
switch boosts the high end. Do experiment with different combinations of the
BRIGHT switch ON and TREBLE down
compared to the TREBLE turned up and
the BRIGHT switch off. You will find
that with the BRIGHT ON and TREBLE
down, the sound will be a little less midrangy compared to the BRIGHT OFF and
TREBLE turned up.
12) GAIN CHANNEL 2: The gain control adjusts the amount of overdrive (distortion). You’ll find the control “comes on”
rather slowly to make it easy to zero in on
just the right amount of moderate breakup.
Past about 1:00, the gain really ramps up
4
3
10
8
12
quickly and moves into serious high gain
territory. As always, lower settings of the
gain control will result in a tighter, more
defined sound. Higher gain settings are
more fun and make an amp easier to play
but can get more compressed and muddy.
13,14 &15) TONE CONTROLS FOR
CHANNEL 2: The Rebel overdrive
channel features the passive tone control
circuit similar in design to the one found
in many classic British amps. The range
and feel of these controls should be familiar to most players and makes it really easy
to dial in great tones with minimal knob
“twiddling”.
16) VOLUME CHANNEL 2: Adjusts the
overall loudness of the overdrive channel.
17) CHANNEL 2 WATTS: Same as
CHANNEL 1 WATTS but only affects
CHANNEL 2. How cool is that? You can
set each channel’s power individually! Try
turning down the power on CHANNEL 1
for a bit of classic breakup when pushed
and set CHANNEL 2 for maximum power
and definition.
18) CHANNEL 1 WATTS: This knob
lets you adjust the actual power output on
CHANNEL 1 from 30 watts for maximum
headroom all the way down to 1 watt for a
lower volume, squishier feel. This is cool

if you are looking for a little more power
amp breakup.
Note: Keep in mind, especially
when playing live with the band, your
amp will only go as loud as your power
setting will allow. If you find you need to
be louder, be sure to increase the WATTS
knob instead of the volume. If you have
the WATTS knob too low, turning up the
VOLUME control will only result in more
distortion, not more volume.
19) TUBE MIX: This is one of the neatest
features on the Rebel 30. Inside the amp
you will find a pair of EL84 tubes AND a
pair of 6V6 tubes. This unique knob allows
8
9
16
17
you to select a tone with a more “British
bark” by rotating the knob all the way to
the EL84 side. Setting the knob all the
way clockwise brings out the smoother,
creamier tone of the 6V6 tubes. If that
alone wasn’t enough, you can also blend
the tubes together for a unique combination of the two giving you a tonal range
not found in other amps.
Note: When the knob is all the way
to the EL84 or 6V6 end of the control, the
maximum power output is about 20 watts.
Setting the control around 12:00 creates a
unique mix of the tubes and also ups the
power to 30 watts.
10

21
20) PILOT LED: Cool blue color.
21) STANDBY SWITCH: In the center (STANDBY) position, the Rebel is
warmed up and ready to go instantly when
switched to PLAY or SILENT RECORD.
Move the switch to the PLAY position for
live performance. The SILENT RECORD
mode is a great feature that allows you
mute the speaker output(s) and automatically connect the internal load resistor.
This lets you to record directly from the
RECORD LINE OUT on the rear without
having to listen to the speaker(s). Perfect
for late night recording when the family is
asleep.

FINDING THE SOUND YOU WANT!
Below are some suggested knob settings to get you started. Keep in mind these are merely suggestions.
You are encouraged to experiment to find “your tone”.
8
A TIP FOR GETTING THE MOST OUT OF YOUR REBEL-30 HEAD
The less gain you use, the tighter and more defined your low end will be.
TUBE MIX KNOB: We did not include suggested settings for the TUBE MIX because it is truly up to
you as to what sounds best. Experiment with different TUBE MIX settings to find “your sweet spot”.
Keep in mind turning the knob more towards the EL84 will sound a bit more aggressive while the 6V6
setting will tend to be smoother.

1) AC POWER SWITCH: Turns the
main power on/off.
2) AC INLET & FUSE: Connect a
universal IEC type power cord. Be sure
the proper value fuse is installed that
matches the ratings for your country as
indicated on the rear panel.
3) AC VOLTAGE SELECTOR:
Makes the Rebel 30 compatible with
the line voltage in any country. Proper
setting of this switch is absolutely
critical. Be sure the switch position
matches the line voltage in your country. Severe damage will result from
improperly setting this switch and will
void your warranty, as well as destroying your amp.
4) 315mA FAST BLO FUSE: This
fuse is 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
blow and there will be no sound. If the
amp appears to be “lighting up” normally but there is not output, check this
fuse. If it is blown (open), this indicates
on or more output tubes has failed and
must be replaced.
Use the troubleshooting method below to determine if a power tube has
shorted.
a) Turn the power off.
b) Set the TUBE MIX control to
the 12:00 position.
c) Allow the power tubes to cool
10
5
6
7
3
and remove the two 6V6 tubes.
d) Install a new 315mA FAST
BLO fuse in the holder.
e) Place the STANDBY switch in
the standby (center) position
f) Move the STANDBY switch to
the PLAY position.
g) If the amp makes sound and
the tone is normal, this is a clue
that one of the 6V6 tubes is bad.
h) If the 315mA fuse blows, one
of the EL84 tubes is bad.
i) Next, turn the power OFF
again and allow the tubes to cool.
j) Remove the EL84 tubes and
reinstall the 6V6 tubes.
k) Turn the power back ON while
in the STANDBY mode.
l) Move the Standby switch to
the PLAY position.
m) If the 315mA fuse does not
blow, the 6V6 tubes should be fine.
n) If the fuse does blow, one of
the 6V6 tubes is shorted.
o) Replace the bad PAIR of tubes
with a same rated pair from
Egnater (1-877-EGNATER) and
you will be fine.
NOTE: This is a useful trouble
shooting technique if you are on the job
and your amp dies. Once you determine
which pair of tubes is bad, you can
safely operate the amp with only the remaining good pair until you can get the
amp properly serviced. Obviously you
must at least carry extra 315mA fuses
in order to do this. Spare tubes would
also be a really good idea.
5) FOOTSWITCH: Plug the supplied
Rebel 30 pedal in here for remote control of the channel selection and reverb
on/off functions.
6) EXTENSION SPEAKER: Used for
connecting an external speaker along
with the internal combo speaker(s).
Since the MAIN speaker output is
labeled “USE FIRST”, you can assume the EXTENSION speaker output
would be “use second”. See the chart
later in this manual for proper setting of
the IMPEDANCE switch when using
extension speakers.
7) MAIN SPEAKER OUTPUT:
Labeled “USE FIRST” because you
must….use this jack first. There is
a special circuit in the Rebel 30 that
helps protect the amplifier from damage in case you forget to plug in a
speaker and try to play the amp. As
we all know, NEVER operate any tube
amp without a proper speaker load
connected! The exception would be
the Rebel 30 combo or head only when
used in the SILENT RECORD mode.
This would be the only instance where
it is OK to use the amp with no speaker
connected.
8) IMPEDANCE SWITCH: Set this
switch to match the impedance of the
speakers. The proper setting for the
8
9
Rebel 30-1x12 combo is 16 ohms. The
setting for the Rebel 30-2x12 combo is
8 ohms.
The correct setting for the IMPEDANCE switch, when in the SILENT
RECORD mode, is 16 ohms for the
Rebel-30 1x12 and 8 ohms on the 2x12
to properly match the internal load
impedance. These settings are the same
as for the internal speakers.
The correct setting for the Rebel 30
Head when using only the Silent
Record mode is 16 ohms.
9) RECORD LINE OUT: This is a
balanced cabinet simulating output
designed for silent direct recording or
as an alternate to placing a microphone
in front of the speaker for live sound
or recording. The frequency response
curve of this output very closely
mimics the sound of a mic’d speaker
cabinet. The RECORD LINE OUT is
always on when the STANDBY switch
is in the PLAY or SILENT RECORD
mode. It is OFF in the standby (middle)
position. With the STANDBY switch in
the SILENT RECORD setting (down),
an internal load is active along with the
RECORD LINE OUT to allow the all
tube power amp to be safely operated.
CAUTION: In the PLAY mode,
you MUST always have a speaker
connected to the MAIN speaker output
jack.
10&11) REVERB LEVELS: These
10
12
11
controls allow you to add any amount
of reverb to each channel individually. The Rebel 30 reverb has a unique
feature we call “spillover”. Most amps
with separate reverb knobs for each
channel simply switch controls when
changing channels often causing either
an abrupt cutoff of the reverb tail or a
swell in the reverb level before decaying away. The “spillover” feature allows the reverb to decay naturally even
when switching channels.
12&13) 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. It must be essentially transparent,
meaning it shouldn’t “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 following method:
a) Set your amp/preamp volume
levels for normal playing
levels. Connect a high quality
shielded cable from the series
send jack to the effect input.
b) Adjust the effects unit input
level to “just peak” while
playing your most aggressive
licks.
13
c) Now connect another high
quality shielded cable from the
effect output to the return jack.
d) Adjust the effects unit output
level to the match the volume you heard before connecting
the return cable. You can check
this by pulling the cable in and
out of the return jack while
playing and verifying there is
no substantial volume
difference. This is called “unity
gain”. A cool “techie” phrase
for “you get out what you put
in”. If your effects gadget does
not have level controls, it can
be assumed you will get unity
gain when plugged in.
NOTE: Depending on how loud
you play, the level at the loop may
be higher than normal guitar level.
Though many floor type and tabletop
effects may work, some may tend to
overload. You will know an effect is
not made for higher levels if, when
you plug it the effect into the loop, you
notice distortion and/or a loss of volume. Most modern effects (including
many pedals) can operate just fine in
an effects loop. We have gone to great
lengths to make the Rebel loop compatible with as many different effects
gadgets as possible.

REBEL-30 HEAD
TECH NOTE #101 WATTS vs VOLUME and other stuff….
There is some confusion about the
relationship between watts and volume
(loudness). There is much discussion
about how this many dB is twice as
loud as that many and that many dB is
double the power and blah blah……
lot’s of techie rambling but no real world
explanations. I’ll try. Let’s say you have
a guitar amp with a knob to adjust the
power (watts). Now say this amp is 20
watts at its maximum power setting and
1 watt at the lowest knob position. It
would be reasonable to assume that 20
watts should be loud enough to play with
the band and 1 watt would be whisper
volume. Anyone who has had the opportunity to test this theory has found
quite the contrary. 20 watts through a
reasonably efficient speaker is quite
loud. 1 watt through the same speaker
is also quite loud. What’s up with that?
Have you ever seen the specs for a 12”
speaker? A typical guitar speaker will
produce about 95 to 100dB at 1 meter
(about 3.3ft) with 1 watt of input power.
Now put 2 or 4 of that same speaker in
a cabinet and the output is even higher.
What this is saying is that even with a
mere 1 watt of power, that speaker will
put out the volume about equal to a person yelling. Obviously not “TV watching” volume. To obtain that whisper
volume, you might need as little as 1/10
of a watt but…….at that low a volume,
most guitar speakers start to sound terrible. In addition, there is a phenomenon
that occurs with human hearing that is
documented by Fletcher and Munson
(two really smart guys) that graphs the
way we hear things at different volumes.
Look it up on the internet. The Fletcher/
Munson curves show how our ears, at
lower volumes, are less responsive to
low and high frequencies. That means
the quieter you play, the more we tend
12
to want to boost the bass and treble to
compensate for our own hearing. Ever
seen the “loudness” contour switch on
a home stereo? That is what the switch
does. It boosts the treble and bass to
make it sound better quiet. On a guitar
amp you often find knobs for boosting
the low and high end in the power amp
section. Typically these controls are
called Presence for the high end boost
and Resonance or Depth or Density (Egnater) for the low end. At low volumes
you typically turn those controls up but
the louder you play, the more you find
you need to turn them down. Fletcher/
Munson again.
Because we make guitar amps with
variable power (Rebel) and switchable power (Tourmaster and Modular),
we get inquires about this all the time.
Often players will use one of our amps
and it appears that the power cut feature
doesn’t do much. Please allow me to
explain.
Let’s say you are playing an amp
at home or in a music store at relatively
low volume. Recall what was said earlier about how little power it really takes
to get a fairly loud volume. If you’re
playing quiet, you might be using even
less than 1 watt to obtain the loudness
you’re at. If you have a chance, try this
on a Rebel. Play fairly quiet and turn the
WATTS knob from 20 watts to 1 watt.
What do you hear? Very little change!
Why? Because at that volume you probably are not even using up 1 watt let
alone 20 watts. Sort of like driving a car
at 5MPH. It doesn’t matter if the engine
is a 100HP or 500HP, you are still only
going 5MPH and using very little HP
to maintain that speed. Same with your
amp. To cruise along at low volume
requires very little power (watts). Having the extra horsepower (watts) doesn’t
make the amp louder when you play at
low to medium volume.
Now try this with your Rebel. Set
the power to 20 watts, turn the master
full up and turn up the gain knob until
you start to hear some distortion. It will
be loud. While you’re playing turn the
WATTS knob down. You will clearly
hear and feel the way less power creates
a spongier, lower volume tone. Some
players are saying the knob isn’t really
cutting the power but is reducing the
headroom. Call it what you will, the result of reducing power is more of a “feel
thing” than a volume thing. Ultimately
the idea is to set it to where you like the
sound and be happy…..play your guitar.
While we’re on the subject of the Rebel,
there has been some talk about how,
when panning from the 6V6 tubes to the
EL84 tubes, the tone difference is not
what some expected. It is believed that
by simply changing power tubes you can
make a Fender (6L6 power tubes) sound
like a Marshall (EL34 power tubes) or
a Vox (EL84 power tubes). What you
are hearing in the Rebel when you go
from 6V6 to EL84 is the real difference in the sound of those two types of
tubes. It may not be quite as dramatic
as many believe but that is the reality of
it. The tonal difference between various types of tubes is more subtle than
many believe. A few people have even
been disappointed when using the TUBE
MIX features because their expectations
of what should happen were really not
based in fact. The intangible characteristic is the change in “feel” between
different types of tubes. These subtle
differences do become more apparent at
higher volume when the power tubes are
“pushed” a little more into overloading.
What you are hearing in the Rebel is
“the truth” about power tubes.
TECH NOTE #102 Sound dispersion
Ever wonder why your 4x12 cabinet
sounds better when you stand off to the
side? Did you consider why the pros mic
a speaker from the edge instead of in the
center? Ever have people in the audience
tell you your guitar tone is really loud
and shrill but it sounds great to you onstage? This is a result of the directionality of loudspeakers. Speakers inherently
do not project all frequencies equally. As
the frequency increases, the dispersion
decreases. In non technical terms, this
means the higher you play on your guitar
neck, the more directional your sound
will be. By nature, speakers tend to be
somewhat non-directional at lower frequencies. This means you can stand off
to the side of your cabinet and you will
hear basically the same bass and lower
mids as your audience is hearing right
in front of your speakers. On the other
hand, and this is where the trouble starts,
higher frequencies tend to “beam” from
the speaker. While you are standing off
axis from your cabinet (not directly in
front of it) you are hearing an even balance of lows, mids and highs and feeling
pretty pumped about your awesome
tone. Unfortunately, unbeknownst to
you, the listeners directly in front of your
cabinets are being killed by the high end
that is “beaming”. FYI, contrary to what
one might deduce, having more speakers in a 2 by 2 arrangement, as in a 4x12
cabinet compounds the problem and
makes the beaming even worse. Next
time you play take a moment to walk
from side to side and squat down in front
of your speakers. You will be amazed
at the difference between listening off
axis (to the side) and listening on axis
(directly in front). Have you ever seen
a band in a small place where you are
hearing the stage volume and wonder
why the guitars sound so bright? Doesn’t
that guitar player hear that obnoxious
high end? That knucklehead must be
deaf!?!? More likely he is standing close
to his cabinets and all that high end is
just blowing past his/her legs so he/she
doesn’t even hear it.
OK..so now I’ve pointed out how
we’ve all been playing for years believing everyone in the crowd thinks our
tone is as awesome as we think……or is
it? Great, so what can you do about it?
The key is to place your speakers so you
are hearing the same thing as everyone
else. If you can get the cabinets far
enough behind you, you probably will
pretty much hear everything just fine.
If that is not possible, try placing the
cabinets pointing across the stage sideways instead of forward at the audience.
At least then you will only be killing
your other band members instead of the
audience. Chances are you often want to
kill the drummer or bass player anyway,
right? The best thing you can do is to tilt
your cabinets so that they are pointed at
your head. I guarantee you will set your
controls way different from what you
normally do.
There are a number of possible options to combat the beaming problem.
A few companies make a solid disc that
you install in front of the speakers to
help disperse or attenuate the high end.
These discs have met with some success though they do introduce some
phasing issues. Also, because there is a
solid piece in front of the speaker, if one
places a microphone in front of the disc
(which happens quite often at shows),
it can sound weird because the disc is
altering the sound into the mic. There are
some other smart people attempting to
address the problem. Most involve using
some form of foam piece in front of the
speakers. The method we find works
best for both live, and when placing
a mic in front of the speakers, utilizes
a sound absorbing 4” x 1” foam disc
placed on the back side of the grill cloth
directly in front of the speaker. The discs
are made of an acoustical foam material
that attenuates the beaming highs instead
of blocking them.
I’m always surprised whenever this
subject is discussed and many guitar
players make the statement “I hate the
way my guitar sounds when I stand in
front of my speakers”. The answer is not
to simply stand off to the side so it only
sounds good to you because everyone
else is still hearing the sound that you
hate. Remember why we play music? It
is for others to enjoy. We should always
make a conscious effort to think about
what the audience is hearing, too.
