safety instructions
& warnings
Please read, understand and follow all safety instructions in this manual, as well
as those on the rear panel of the amplifier. These instructions and warnings must
be followed for your safety, and also to ensure that the amplifier will serve you
for many years. Please use common sense when operating, this is a professional
instrument designed for electric guitar amplification, and should only be used with
electric guitar signals.
• Do not store or operate the amplifier
in damp/wet areas.
• Do not keep items that contain liquid
on or near the amplifier.
• Allow for 4-6 inches of space around
the unit when operating. This unit
produces heat and should be kept
away from flammable items/objects.
• Never obstruct the top heat vent when
the unit is powered on.
• Do not expose the amplifier to high
temperature, keep away from radi-
ators or heat producing/supplying
items.
• Be sure to connect to an AC power sup-
ply that meets the power supply specifi-
cations listed on the rear of the unit.
• Do not use an AC power cord that
is damaged, has been pinched or is
missing prongs.
• This amplifier must be properly
grounded to local standards when
being operated. Do not use 2 pole
extension or power cords to supply
power to this amplifier.
• Remove the AC power cord from the
amplifier when changing tubes, fuses
or when moving the amplifier. Always
replace fuses with the correct type
and rating. Always remove AC power
cord when removing chassis.
• The AC power cord should be re-
moved from the outlet when left
unused for long periods or when there
is risk of electrical storms.
• No user serviceable parts inside, all
service should be done by qualified
personnel only.
• Always make certain the proper load
is connected to the amplifier before
operating. Always make connections
to the amplifier with the power off.
• Your amplifier is designed to produce
high volume/sound pressure levels.
Long term exposure to these levels
can damage your hearing. Please use
hearing protection when exposed to
these levels for extended periods to
prevent loss of hearing or hearing
damage.
• Keep away from children.

set up & power up
It is very important to place the amplifi-
er in a dry location that provides 4-6” of
space between the rear of the amplifier
and anything in the area that has been
designated for the amplifier. Tubes
produce heat, and anything flammable
should be kept away. Verify that the top
heat vent is free from obstruction so
that the heat produced by the tubes can
escape from the interior of the amplifier.
Now have a quick look at the tubes and
make sure they are all seated in their
sockets. Look good? We are ready to
move on!
First, make sure that the power and
standby switches are in the off (down)
positions. Connect the amplifier to a
speaker cabinet using a good quality
speaker cable and set the impedance
switch to the required impedance
setting (See 3.5). Next, connect the AC
power cord to the amplifier Mains con-
nector on the rear of the amplifier and
then to an AC outlet.
At this point, all other peripherals can
be connected to the amplifier as well:
Foot Switch (See 3.9)
MIDI (See 3.8)
FX Loop (See section 4 )
Line Out (See 3.5)
Guitar and cable (See 2.1)
Note: A good quality, shielded instrument
cable is recommended for guitar input
as well as FX loop connections to prevent
unwanted noise. Cables can color the
sound of a guitars signal, and sometimes
trying different cable lengths, can provide
a desired sound.
Once all your connections are made,
move the power switch to the On po-
sition and give the tubes at least one
minute to warm up. Now is a great time
to begin setting all controls while we
wait. We recommend setting the master
volume, channel level and gain controls
to the lowest setting or zero (fully count-
er clockwise) and all treble, mid and
bass controls to the 12 o’clock positions
to begin. Set the bright and contour
switches to the down position, the
standby switch to the Revv (up) position
and you are ready to begin exploring!
Note: Upon power up, you will have
noticed that all channel LED’s light up
for a couple of seconds and then only the
Channel 1 LED remains lit. This is normal
as the amp does a start up sequence at
power up then arms channel one to begin.
This sequence will also assist you when
setting other modes which will be touched
on later in the manual.

Input
¼” Instrument cable input.
Active Input – The active input jack is to
be used with guitars that have active
pickups and work better with lower
impedance than a guitar with passive
pickups. Because active pickups don’t
require high impedance and usually
provide a stronger signal out, this jack
provides the proper circuit in order to
keep the tone of the amp articulate
and preventing unwanted compression
and noise.
Passive Input – The passive input jack is
to be used with guitars that have passive
pickups and require high impedance for
proper signal transfer. This jack is de-
signed to get the strongest signal from a
passive pickup to the first tube stage.

Channel One (Clean)
Selected by: 1) pushing the designated
front panel momentary toggle switch up,
2) foot switch button #1 or a foot switch
preset mode setting, 3) MIDI and CC
commands.
Channel One CLEAN is equipped with a
treble, mid, bass and level control. The
passive EQ controls have a large range
for all different clean variations and
should be adjusted a little at a time while

experimenting with different sounds.
The Generator clean has been tailored
to have incredibly clean tone and is very
responsive and punchy to give you great
versatility in finding the ultimate clean
tone every time!
Channel One (Crunch)
Selected by: 1) pushing the designated
front panel momentary toggle switch
down, 2) foot switch button #1 or a foot
switch preset mode setting, 3) MIDI and
CC commands.
Channel One CRUNCH adds a gain con-
trol and bright switch to the EQ it shares
with the channel one clean mode. These
two modes have been voiced to share
the EQ and still be switchable without
large adjustments.
The gain control on channel one crunch
will take you from a level above clean
at its lowest setting, to an old school
medium gain crunch at full throttle. The
definition of the channel is then compli-
mented by an array of different sounds
and settings once the passive EQ controls
are adjusted to taste. But as always,
adjustments should be made a little at a
time as the range of control is very broad.
Experimentation will expose many differ-
ent combinations of great crunch tone.
Throw the bright switch on and you have
all you need to find your favorite combi-
nation of low to medium gain tones!

Channel Two (Dirt)
Selected by: 1) pushing the designated
front panel momentary toggle switch up,
2) foot switch button #2 or a foot switch
preset mode setting, 3) MIDI and CC
commands.
Channel Two is equipped with a gain,
treble, mid, bass and level (volume)
control as well as aggression, bright, fat
and contour switches.
The amount of gain from the channel
can be selected by the relationship be-
tween the gain control and aggression
switch. There are 3 levels of use from
the aggression switch that shifts up the
amount of gain, as well as the satura-
tion and frequency spectrum. The range
of the gain control itself in either of the
3 aggression settings is fully useable
and will then dial in the amount of gain
desired from the aggression setting
selected. The relationship between the
aggression switch and gain control will
provide anything from a lower gain rock
tone to a saturated metal or lead tone
but still remain super articulate and
well defined.
The aggression setting is foot switch-
able for on the fly selection, can be
saved into the foot switch presets and is
MIDI selectable essentially adding more
channels to the amplifier.
The EQ controls on this channel are
very broad and a little adjustment at a
time is suggested when experimenting.
The range is large and the channel has
been voiced to provide a huge frequency
spectrum so as to make sure nothing is
left out, but still remain very tight in the
bottom end and not too harsh at higher
frequencies. The midrange bite is very
much present and the amount of cut
can be easily tailored with use of the EQ
controls and contour switch.
The bright and fat switches accentuate
the EQ settings and give the channel
more voice options. They do as they are
described and really give the channel
the added versatility that it was de-
signed for without compromising the
channels character. These switches are
foot switch preset saveable and can be
toggled via MIDI or CC commands.
The contour switch shifts the upper
frequencies and changes the voice from
that of a darker focused voice to a more
open and bright voice that becomes pro-
jected and is almost 3 dimensional. Be-
cause the EQ will more than likely need
to be set when the switch is toggled, it
was not designed to be saved via foot
switch presets or MIDI/CC selectable as
it is considered to be an extension of the
EQ itself. This switch is a latching type
and not momentary like the others.
Finally, the level (volume) control adds
the flexibility to keep the volume of the
channel set as you require. Because the
level control is added in the circuit
before the effects loop, it also controls
the amount of crunch channel signal
sent to the loop allowing for balanced
signals from the two channels. This
is a very handy feature that allows for
volume boosts of desired channels with-
out having to be limited to the master
volume controls.
Revv Generator 100w2.5
2.6
Master Volume Control
The Generator is equipped with 2 MIDI
and foot switchable/programmable
master volume controls. These controls
come right after the effects loop and
also work as the FX loop return control.
These controls adjust the global volume
of the amplifier and feed the preamp
signal into the power amplifier and can
be toggled from one to the other for
complete volume control and boosts.
The master volume #1 control is in
use when the red “masters” LED is off.
And master volume #2 control is in use
when the red “masters” LED is on. The
controls can be toggled via the front
panel “masters” toggle switch, the foot
switch button #4 (or programmed bank)
or a MIDI device. The “masters” function
is also foot switch preset programmable
and can be toggled via CC commands.
Depth & Presence
The Depth control is a bass control
and will add some incredible low end to
the output. Using the control sparingly
is recommended to keep the bass re-
sponse tight, as higher setting will give
you a looser bass tone.
Note: Lowering the bass control on the
four channels and increasing the depth
control is also another means of experi-
menting with the voice of the Generator
and the bass response.
The Presence control from the off po-
sition to the 2 o’clock position will give
you a subtle increase in treble, and ev-
erything past that point will then provide
a greater increase for a sharper cut.
Note: These are controls of the power
amp section of the amplifier and are
global controls which affect all channels.
Because they work well with the EQ of
each channel, experimentation will pro-
vide added tone and definition.
2.7
Function Controls
The accessory functions are activated by
the momentary toggle switches. These
switches are assigned 2 functions each
and control the functions when the
switch is pushed in the direction of the
functions label. The LED associated with
each function will then react according
to the state of the function.
A - Masters Switch
The master volume toggle switch is
a momentary switch that needs to be
pushed up in order to toggle between
the 2 master volume controls. The Red
LED is illuminated when master #2 is
in use and off when master #1 is in use.
(See 2.6)
B - Mute Switch
The mute function allows for the amp to
be silenced. This function requires the
front panel momentary toggle switch to
be pushed down to be turned on and off.
The Red LED will flash when the ampli-
fier is in mute.
Revv Owner’s Manual2.7
Mute can also be turned on by holding
down button #4 on the foot switch for
2 seconds. Mute is also MIDI and CC
controllable. (See Section 6)
Note: It is not possible to program mute
into a foot switch preset bank. Button #4
on the foot switch will control mute in any
foot switch mode. (See Section 7)
Note: Mute is a handy feature that is
not found on many amplifiers today. It is
something that takes time to remember
to use instead of fiddling with volume con-
trols and the standby switch. It is also very
helpful for tuning live and should be taken
advantage of whenever possible.
C - Serial FX Loop Switch
The FX Loop toggle switch turns the
serial FX loop on and off, as well as in
and out of the signal path. On and off is
selected by pushing the toggle switch
up and releasing it quickly, in and out is
selected by pushing the toggle switch up
and holding it until the LED flashes.
The on and off selection will set the amp
to use the FX loop and activate the FX
loop foot switch button #3 for use. When
the FX loop is not being used it can be
turned off and the foot switch will react
to this condition by flashing the LED
when stepped on.
The in and out control of the FX loop
simply does what the foot switch would
do when stepped on, it takes effects in
and out of the signal path. This feature
was added to be able to set the in or out
condition of the FX loop to a preset bank
on the foot switch when the foot switch
is in preset mode (See 7.3), or to control
the in or out function when the foot
switch is not plugged in to the amp.
Note: The Generator is set by default to
start up with the FX Loop turned off. If
you want to bypass the feature and want
the FX loop to turn on automatically at
start up, simply turn the power off on the
amplifier, press the FX Loop toggle switch
up and hold it, then turn the main power
switch to the on position. The FX Loop LED
will flash and immediately turn the loop
on. Now whenever you turn the amplifier
on, the FX loop will also be on and ready
to be put in and out of the signal path as
you wish.
D - Store Switch
The store switch is used to program
MIDI (See section 6) as well as set the
MID channel. (See 6.3)
When the amplifier is powered up, by
pressing the store toggle switch down,
the store LED will begin to flash. At this
point, the amplifier is waiting for a MIDI
program command to be received. Once
received, the current amplifier configu-
ration will then be saved to memory so
that anytime the program command is
received via MIDI; the amp will switch
itself to the saved configuration.
Note: When in store mode, once a MIDI
program command is received, the LED
will flash quickly then turn off signaling
the user that a program command has
been received and the amps configuration
has been stored to memory.
Revv Generator 100w2.8
Standby & Power Switch
The power and standby switches give
the amp power from the mains, as well
as high voltage through the circuit. First
turn on the power switch and wait a
minute to allow the tubes to warm up.
Turn on the standby switch to the Revv
position once you are ready to play.
Note: NEVER power up the amplifier with-
out the proper speaker load connected!

Bias Test Points
The amplifier is designed to allow the
user to set the bias of the power tubes
without taking the chassis out of the
head shell. Each pair of power tubes
needs to be set according to the tubes
being used. (See 5.4)
Power Tube Fault Fuses
The power tubes are fused in pairs.
Should a power tube fail, the fuse will
blow and take the pair of power tubes
out of service. This has the benefit of
protecting the amplifier, but also allows
for playability, so as to allow the user
to finish the gig on the remaining pair.
The volume and tone will change but the
show will go on.
Note: Should the amp be run with 2 power
tubes removed from service (Bad or blown
fuse), in order to get the same tone as 4
tubes, the amp should be run with an im-
pedance setting of half the speaker cabinet
rating. For example, if the speaker cabinet
is 8 ohms, set the amplifier to 4 ohms, and
if the speaker cabinet is 16 ohms, set the
amplifier to 8 ohms. This will improve tone
and run the tubes more comfortably when
2 are taken out of the mix!

Revv Owner’s Manual3.5
Impedance & Speaker Jacks
The amplifier must always be connected
to a speaker cabinet or load when it is
powered up. The Generator amplifier
can be used with cabinets that provide
a load of 4, 8 and 16 ohms. Because the
amplifier provides 2 speaker jacks, it
can also power 2 cabinets directly from
the amplifier, but the impedance will
need to be set correctly.
Most set ups are simple, one cabinet
plugged into the amp, set the imped-
ance to that marked on the cabinet and
your ready to go! But when it comes to
adding more cabinets to the rig, then
you need to set the impedance correctly
to prevent damage. Most rigs don’t usu-
ally run with more than 2 cabinets so we
won’t go beyond 2 cabinets here.
Some examples:
2 - 8 ohm cabinets would be run to the
Generator (one per speaker jack), the
correct impedance switch setting would
be 4 ohms as they are being run in parallel.
2 - 16 ohm cabinets would be run to
the Generator (one per speaker jack),
the correct impedance switch setting
would be 8 ohms as they are being run
in parallel.
2 - 4 ohm cabinets cannot be run in par-
allel with this amplifier. This will cause
damage.
Note: No damage will result when running
the amplifier set at a lower impedance
(Ex: 4 ohms) into a cabinet rated at a high-
er impedance (Ex: 8 Ohms). But running it
the other way around will possibly cause
damage to the output transformer or
other components and it is suggested that
the amplifier never be run into a lower
load than what the amplifier impedance
switch is set at when hooking up speakers
in different configurations.
Note: Depending on the power tubes used,
the Generator can supply 180 watts+ of
power to the speakers at high volumes, so
it is important to be sure your cabinet can
handle that kind of power, especially when
running KT88/6550 type tubes. If that is
not the case, then it is recommended to
keep your volume levels lower to prevent
speaker damage.
3.7
3.6
FX Loop Connections
The FX loop connections are to be
hooked up to external pedals or effects
units. The Send level will supply the
signal required and needs to be set
accordingly with the send level control.
(See 4.4)
Line Out
The Line Out jack and level control pro-
vide a signal that is taken right off of the
speaker jack. This can be used to run
the Generator into another power amp
for more power. Returning the signal
back is not required as it is a direct out
and not a send signal like on an effects
loop. Use a ¼” mono plug.
Note: Never run the amp without a speak-
er connected to the speaker out jacks! The
line out can never be used without a load
connected to the speaker jacks!
Revv Generator 100w3.8
MIDI Connections
The MIDI IN connection is for external
equipment connections when the need
to control the Generator with other MIDI
equipment or Revv Products is desired.
The MIDI IN connection can also provide
12V DC phantom power to power the
external equipment (See 6.1). The MIDI
through connection allows for daisy
chaining of other MIDI devices.
3.9
Foot Switch Connection
This connection is for the foot switch
which communicates with the ampli-
fier as well as powers the foot switch.
Should the provided foot switch cable
ever fail, any Ethernet cable can be used
when in a pinch. However, the cable
sends data between the amplifier and
foot switch and if a low quality cable is
used, communication between the 2
devices may suffer causing incorrect
switching or erratic behavior. A high
quality cable is recommended which can
be provided by Revv should you need a
replacement.

serial effects loop
The effects loop has been designed to allow it to be foot switchable, preset able, as
well as MIDI and CC controllable. It has also been given an On and Off control ability
Speaker Cab Lighting
Revv speaker cabinets each have a
light up logo that is powered from the
cab lighting jack on Revv amplifiers.
This is a 4 pin DIN jack that should be
connected to the 4 pin DIN jack of a Revv
speaker cabinet. A cable with 2 – 4 Pin
DIN connectors is to be used to connect
the cabinet and amplifier together. The
logo on Revv speaker cabinets change
colors with the amplifiers logo to add to
the great look of the Revv amplifier and
cabinet rigs.
Note: This jack can only be used with Revv
speaker cabinets.
Revv Owner’s Manual

SEND Level Control
Some effects units have meters on them
to show you what level of signal they are
receiving and some do not. For those
that do not have them, simply turn the
send level control up until you are happy
with the volume, or until your effects
begin clipping, in which case you are
driving them too hard and have found
your maximum setting. The master
volume controls on the amp also work
as return signal controls, so they will
need to be adjusted once your send level
is set up in order to drive the power amp
to your desired volume.

switch the effects loop in and out of the
signal path to make it easier to apply
and remove effects to the guitar signal
on the fly. When the effects loop is being
used (On), the send level control on the
amplifier must be set to send the signal
level that is required by the effects units
or pedals being used. Because this level
control can get messed with when mov-
ing the amp from place to place, venue
to venue, we also found the need to add
an on and off ability to the amp, to pre-
vent a gig or jam from going bad when
the effects loop is switched in and your
instrument drops out of the mix because
the level control was turned off com-
pletely by accident. (Hey, it’s happened,
and we’re just trying to help you so your
drummer can’t rub it in later!)
If you did forget to set up the FX loop
and turn it on, when you press button
#3 on the foot switch, it will simply flash
the LED a few times letting you know it’s
not going to put the loop in, because it
has not been turned on, saving you from
your instrument dropping out of the mix.
You might not have effects, but at least
you can still be heard!
So, for the switchable effects loop to be
used, it must be turned on. This is done
on the amplifier itself only and cannot
be turned on by the foot switch. But
when turning it on, be sure to set the
send level control accordingly so that
you will be heard.
to have the send level control and FX Loop jacks removed from the signal path. It is
designed to be of the highest quality possible and is transparent. It is tube driven
with the send output buffered at 900 ohms.
Note: The Generator is set by default to start up with the FX Loop turned off. If you want
to bypass the features benefits as described below, and want the FX loop to turn on
automatically at start up, simply turn the power off on the amplifier, press the FX Loop
toggle switch up and hold it, then turn the main power switch to the on position. The
FX Loop LED will flash and immediately turn the loop on. Now whenever you turn the
amplifier on, the FX loop will also be on.
Note: The effects loop will need to be turned on in order to be controlled via MIDI Pro-
gram patches as well, unless it is set to turn on automatically at power up.

FX Loop Hook up
Let’s go through it step by step, just in
case you have never used an effects loop
and don’t know how to hook it up.
First, you need to hook up your effects
units to the Generator. The send jack
will need to be connected to the input
or in jack on your effects unit. The out
jack on the effects unit (or last pedal in
your chain) will then connect back to the
return jack on the amp.
Next, turn on the amp and turn the
effects loop on by pressing the FX Loop
toggle switch up on the front panel, you
should see the red LED light up and
the effects loop is now on and in the
guitar signal path. Adjust each channels
level control to your liking and set your
send level control and master volume
as stated above. Once that’s done, your
FX Loop is set and ready! If you hear no
sound at all, have another look at the
send level control as it’s probably set
to zero!

FX Loop In/Out
In order to put the effects loop into the
signal path, it needs to be turned on first
(See 4.1). The effects loop, once turned
on, can be put in and taken out of the
guitar signal path in a few ways.
1) The front panel toggle switch, when
held for 2 seconds will toggle the loop
in and out. This method of toggling the
loop is designed for foot switch preset
setting (See 7.1) but can be used for
FX Loop in/out toggling as the user
requires from the front panel of the
amplifier when the foot switch is not
plugged in.
Note: When the FX Loop in/out is toggled
from the front panel by holding the switch,
the LED will flash 4 times when it is in, and
3 times when it is out of the signal path.
2) The foot switch, when not in preset
mode, toggles the effects loop in and
out of the signal path when the FX Loop
is turned on and button #3 of the foot
switch is pressed. The foot switch LED
#3 will illuminate when it is in, and turn
off when it is out of your signal path.
3) The FX Loop can also be controlled
via MIDI and CC commands from exter-
nal equipment. Simply program the amp
for MIDI programs or use CC commands
to do so. (See Section 6)
Note: The level controls on each channel
will also affect the send level being sent
from the effects loop, when one is higher
than the rest you will find your signal
changes when using that channel. Be sure
to test each channel and the send level
coming from the effects loop send jack. Its
best to set the level of your channels first
then adjust your effects loop send level.

Power Tube Sockets & Tube Type
The Generator has been designed to
allow mixing of power tubes as each
pair has its own bias adjustment. Tube
positions 1 and 3 are set up as one pair
and are biased with the bias adjustment
trimmer next to tube 1, and tubes 2 and
4 are the second set that are biased with
the adjustment trimmer next to tube
2. This allows the user to mix different
power tubes in the amp to get a desired
sound. So a set of KT88 tubes can be
used with a set of EL34 tubes and the
benefits of using both tubes can be
mixed together, or maybe you prefer a
set of EL34 tubes with a set of 6L6GC.
Tube Pair 1: V1 and V3 – set bias with
trimmer next to V1.
Tube Pair 2: V2 and V4 – set bias with
trimmer next to V2.
Note: While we have equipped the ampli-
fier to have this great feature, we advise
that all tubes be set up by a qualified
service technician to prevent damage to
the amp from improper bias settings.

Power Tubes
We have found these tubes to best fit
the tone of this amplifier and for optimal
performance we recommend them.
Here are a few characteristics of the
tubes we find with the amplifier.
KT88 – This tube is punchy with a strong
low end and a great clarity. The extra
power out of this tube adds extra head-
room and is very tight and focused.
6L6GC – The 6L6GC tube is big, open
and articulate. These tubes come stock
in the Generator as they provide the low
end and clarity that we find to work best
with this amplifier.
EL34 – The EL34 tubes are more ag-
gressive than the KT88, they add more
harmonic content and have a bit more
sizzle on the highs. The low end still re-
mains tight, this tube also compliments
the Generator tone.
Note: The tubes listed above are guaranteed
to bias correctly in the amplifier, but other
tubes can be used in the amplifier as well.
6550, KT77, KT66, 5881 are some examples
of other tube types that can be used.
