INTRODUCTION
Leviathan is a two channel modern hi-gain style guitar amplifier. Thought of as the ultimate tone
weapon, featuring a rich crunchy crisp sound and a tridimensional multi stage hi-gain overdriven
channel.Full MIDI implementation (CC and PC), double master volume and with a serial high
voltage buffered effects loop it makes Leviathan your life as guitarist easier than ever before.
Additional information and audio/video demos can be found at www.redseven-

POWER SUPPLY
Leviathan is shipped with hardwired primary voltage. 240V, 230V or 115V must be chosen at order
time.

NOTE: IMPORTANT…NOT TO DO!
• Do not try to change output jacks (impedance) while the amplifier is turned on.
You must turn STANDBY and POWER switches to OFF position before changing the
output impedance.
• Do not try to change input/output levels of you devices plugged into the fx loop
while the amplifier is on. You must turn STANDBY and POWER switches to OFF
position before changing input/output levels of your gear plugged into the fx loop
or at least disconnect the cables from SEND and RETURN jacks.
THIS OPERATION CAN LEAD TO A FINAL BREAK DOWN OF THIS
AMPLIFIER. IN THESE PARTICULAR CASES, REDSEVEN AMPLIFICATION
WILL NO BE
RESPONSIBLE FOR ANY DAMAGES TO THE AMPLIFIER ITSELF OR
PEOPLE. PLEASE KEEP IN MIND THAT YOU ARE HANDLING A DEVICE
WITH POTENTIALLY LETHAL VOLTAGE. PLEASE CAREFULLY READ THIS
MANUAL BEFORE TURNING THE AMPLIFIER ON.
REDSEVEN AMPLIFICATION ARE NOT RESPONABLE FOR ANY PARTS
SUBJECT TO WEAR (LIKE TUBES, POTS, CAPACITORS, ETC).
WARNING!!

This amplifier uses potential lethal voltage, it must be used only
by expert people!
WARNING!!
Before insert power cord inside Leviathan, check the voltage
plate under IEC socket and be sure to match wall voltage of
your country.
By developing this amplifier we had few main visions in our minds:
1 –THE AMPLIFIER MUST SOUND GOOD IN A MUSICAL CONTEXT AND NOT IN
YOUR BEEDROOM EXCLUSIVELY.
This can be hard to understand for some people, but in every step of our
developing process we have recorded it through a professional studio recording
system, ensuring that useless frequencies which can fight with bass guitar, synths
or maybe cymbals in a live/recording environment are gone. A huge quantity of
useless gain can be a bad thing too and we have taken care of this too!
2 –ALL THE DISTORTION CIRCUITS ARE 100% TUBE BASED, NO DIODE CLIPPING
HERE.
For this project we have focused on dynamics. We found out by having too much
gain and compression (like for example achieving this with diodes or LEDS) is
totally useless for this purpose. Weʼre not judging anyone here, we only want to
explain the idea we had regarding this particular amplifier. This time we try to
reach the maximum gain possible on CH2, by keeping perfect separation between
strings, even in some crazy drop tuning.You will find an amp that talk best with
your pick control and your volume control, capable of obtaining a multitude of
sounds , even on one channel only. Dynamics and control are everything for us.
3 –MIDS IS EVERYTHING.
The mid frequencies is where your guitar amplifier lives. This mean you need
good mids and the right frequencies to pop out of the mix without having any
volume problem. We have changed quite a bit how the usual mid control works in
6
almost every guitar amplifier. By doing this we have developed a very sensitive
mid control on the distorted channel, making sure that you have a very special
and musical way to express those delicate frequencies.We believe in mids, do not
underestimate this frequency range, weʼre serious about this!
SOUND DESCRIPTION
L120 was born from the demand of our clients to achieve the most brutal hi-gain
sound we can obtain from an amplifier, with our twists on top of that. This became
a two channel amplifier without any clean channel, the perfect hard rock/heavy
metal machine.
We are proud to say that this is 100% not a clone of anything. You will not find any
ingredients from any other builders inside. Like it or not. Here is a resume of the
sonic features of this particular amplifier:
- CH1: this channel was made from scratch. We have two faces here, a “normal
mode” which is the nearest sound to a clean amplifier, but you will not have that
crystal clear tone. This is not a bad thing at all, because here you will find some
excellent blues tones using both single coil and humbucker pickups. Something
probably not expected from an amp like this. “Hot mode” is where the fun begins.
Hot rodded tones, with an amazing extraordinary variety of sounds. Equalization is
way more effective than your in your typical standard guitar amplifier, with mid
7
controls you can achieve everything from a scooped metal sound to a vintage style
hard rock sound. Quite a lot gain is available here, perfect for solo parts indeed.
- CH2: the most brutal hi-gain sound available from our catalog. This is something
almost insane for our standard but at the end of the day, lots of music genres use
this quantity of saturation. The eq section is something youʼll probably never heard
before: forget about those harsh highs, scooped mids and farty basses that a lot of
extreme amps have. Here we have something like aggressive highs, a sweepable
mid, capable of some really unique heavy metal tones along with some incredibly
mid boosted hard rock tones, always with really tight bass frequencies. To be honest
this is probably not the most high gain amp ever, thereʼs a few amplifiers in the
market who run higher gain, but with all probability this is the one that will make
you cut thru the mix every single time and with any eq position. The extraordinary
achievement here is in fact the separation between strings even with the gain at 10
on CH2.For this particular model we have also added a global depth control on
the back, along with the classic presence control. The Depth control helps you to
define the right amount of the bass frequencies in the power amp, so it makes it
easier to dial in your drop tuned guitar without having any farty or fuzzy sound at
all.
TECHNICAL FEATURES
FRONT PANEL:
(from left to right)
•STANDBY / ON SWITCH: turn the amplifier in standby mode or in operative
mode.

•RED LED: (under STANDBY / ON SWITCH): this led will indicate the state of
incoming power supply. It will turn on if everything is ok.
•BLUE LEDs: when on, CH1 is activated.
•RED LEDs: when on, CH2 is activated.
•BLUE LED (on the white line, up to CH1 EQ): when on, Hot mode is activated.
•RED LED(on top of master volumes): indicate which Master Volume is active.
POTS:
•CHANNEL 1: Volume, Treble, Bass, Middle, Gain.
•CHANNEL 2: Volume, Treble, Bass, Middle, Gain.
SWITCHES:
•CHANNEL 1: Bright switch (bright / normal), Hot mode (on/off).
•CHANNEL 2: Bright switch (bright / normal).
COMMON:
•MASTER VOLUME: master 1 and master 2, they acts on both channels.
REAR PANEL
(from left to right)
•SEND & RETURN: Connection between pre amp and power amp. L120 is
9
shipped with pedal friendly signal level.
•MIDI IN & MIDI THRU: sockets for midi communications. Midi IN receive midi
signal, Midi THRU left midi signal pass thru without modify original messages.
•STORE SWITCH: tactile switch for saving combinations of sounds into
amplifier digital memory.
•FOOTSWITCH: input jack for Leviathan L120 footswitch. Pay attention: others
footswitches can damage the amp.
•PRESENCE: global setting for presence control. It acts on both channels.
•DEPTH: global setting for depth control. It acts on both channels.
•OUTPUT: output jacks for connect the amp to a cabinet. Please read carefully
the impedance before connect your cabinet.
•LINE OUT: jack and level pot for line out signal, taken from the output jacks.
Please remember you MUST use a cabinet anytime in conjunction with this
output. Using Line Out by itself without any load will damage this amplifier.
•HT FUSE: (1A slo blow) high current fuse. Replace ONLY with same type.
•MAIN FUSE: (2.5A slo blow) input voltage fuse. Replace ONLY with same
type.
•IEC SOCKET: connect power cable here.
•POWER ON / POWER OFF SWITCH: turn the amplifier on or off.
FIRST USAGE
Before plugging in the power cord, make sure to check the input voltage of the
amplifier and be sure to match it with your wall voltage, and then insert the power
chord.Before plugging in the speaker cable, check the impedance of your cab and
match it with the output impedance of the amplifier, then connect the speaker cable
10
from cabinet to amplifier.Now youʼre ready to put the Power Switch in “POWER
ON” position.Leave the amplifier in this state for at least thirty seconds. Plug your
signal cable into input jack and youʼre ready to put the Standby Switch in “ON”
position. Now you can rockʼnʼroll!
