Congratulations!
We would like to thank you for purchasing the G20D2 Electric Guitar Amplifier.
It has been specially designed and developed for the use with electric guitars.
Before using your new amplifier, we advise to read the following pages carefully.
Taking care of your G20D2
Safety Warnings
We want you to be aware of certain safety aspects,
for reasons of product safety and liability. With
all due respect, please read the following before
operating your new Fame amplifier.
• Do not use or store your amplifier in or near
moist or wet areas.
• Make sure that voltage shown on the back of
the amplifier is the correct voltage for the
location you are using it. The G20D2 can
never be used at different voltages than shown.
• Opening the amplifier housing must only be
done by authorized personnel. No user
serviceable parts inside.
• The power amp is configured to deliver highest
tone at normal volume levels. We advise you
for your own good not to expose yourself to
very high volume levels for long periods of
time. It can lead to hearing damage.
Transporting the G20D2
• The G20D2 is a solid state instrument
amplifier. The built-in circuits are sensitive to
hits, especially when hot. To avoid damaging
the unit, we recommend using care during
setup and tear down of the unit.
• Allow the amplifier to adjust to the ambient
temperature before operating, 10 minutes
should be sufficient in all cases. Especially the
change between a cold vehicle and, in most
cases, warm stages can cause condensing
fluid inside the electrical circuit. This can lead
to circuit shorts.
• For continued road use, please protect the
amplifier with a professional flight case. Trans-
port only in operating position. Do not trans-
port upside down or on its side.
Daily use
• Never be rough with knobs, connections
or other parts of the amplifier.
• Be careful while pulling out cables. Pulling
plugs quickly can cause damage.
• Disconnect all cables before transporting
the unit.
• Avoid physical shocks, such as hits or drops.
• You should never put any heavy items on top
of the G20D2.
Cleaning the G20D2
• Usually it is sufficient to wipe down the outside
of the amplifier with a slightly moist
cleaning rag.
• Do not use any abrasive cleaning chemicals.
• Sometimes a vacuum cleaner can be used to
remove dust and dirt from nooks and crevices.
• Avoid putting any vinyl on top of the unit.
It glues and discolours the surface.
Electric enviroment
• This amplifier contains electric circuits, which
can cause interference when operating near
Radio or TV units. If you notice any abnormal
noise, we recommend to put the amplifier
away from such devices.
• Blown fuses can only be replaced with fuses
of equal values. The use of incorrect fuses is
prohibited and can cause severe injury or
damage of the amplifier.
• Only use a grounded power cable in good
condition.

Setting up the GS2-158D
WARNING!
To avoid electrical shock or any other damage, make sure that the G20D2
and all other devices are switched off before you start connecting them to the
amplifier!
Power Connections/Mains
Before connecting to a grounded power outlet, make
sure the power switch (on the backpanel) is in the
off position (facing up). The G20D2 is set up for 230
V of line voltage. Once the amplifier is plugged in,
you can get started!
Connecting an electric guitar
The input jack on the left side of the frontpanel
receive your electric guitar signal by means of a
shielded guitar cord with 1/4” mono style plug.
Make sure the master volume of the amplifier is set
to the lowest position to avoid disturbing noise while
connecting.
Speaker protection
The G20D2 has a built-in 8” speaker. It can be
damaged by heavy feedbacks of the connected
instruments. You should always keep a sufficient
distance to the amplifier to avoid such feedbacks. This
will extend the life of the speaker and the power amp.
Traveling Abroad
If traveling to countries outside the EU, always check
their local voltage before operating the G20D2.
Mismatched voltages can and most likely will destroy
your amplifier. Should you encounter voltages and
frequencies other than those indicated, a transformer
must be used between the power socket and the
GSG20D2. This transformer must be able to transform
thevoltageandfrequencytooneoftheindicatedsettings.
Main Fuse
The main fuse is situated in a little drawer which is
part of the power input jack. This sliding fuse holder
also hides a spare fuse. For 230 V, the fuse must be
a 0,5A slow blow. It is crucially important to use the
specified fuse values only.
Maintenance
All checkups and repairs must be undertaken by
authorized service personnel. With the right treat-
ment, the electric circuit and the power amp will not
need any kind of maintenance at all.

Periphal Connections/Preamp
Signal In Jack
On the very left side fo the frontpanel you will find a
6,35mm mono style input jack for the connection of
your electric guitar.
CONNECTIONS ON THE BACK
Mains
This jack is used to connect the G20D2 to a grounded
power outlet. Please make sure that the power cord
works correctly and has a shielded plug.
CD In
These RCA input jacks can be used for the signal of
an external MP3-/CD-Player. This stereo signal will
also be heard on the headphones, if connected. SO
you will be able to jam to your favourite songs and
playbacks.
Phones
For quiet practicing at home you can also use
optional headphones. For best performance and a
brilliant sound, we recommend our Fame DT 790
studio headphones. Please note that the overall
volume of the amplifier will influence the master
volume of your headphones.
PREAMP OF THE G20D2
Clean
In this mode, the amplifier produces a very bril-
liant and percussive sound. Due to the fact, that the
G20D2 features a very small loudspeaker, you
will notice an enhancement on mid and high
frequencies.
Overdrive
This mode features an overdrive of the amplifier’s
preamp. The range goes from a slight overdrive up
to high gain distortion sounds.
Your guitar cord is an important part of our signal chain and its quality and
construction type clearly affect the overall tone of your rig. Try and buy the
best quality cord you can or want to afford for maximum sound!

Controls and Switches
We suggest you start exploring the channels with all controls set to 12:00
o‘clock and the master volume slightly cracked open.
Gain
Controls the preamp‘s intensity. With activated
Overdrive mode, it is responsible for the amount of
distortion in the overall sound.
CLEAN/OVERDRIVE
Switches between the two preamp modes of the
G20D2.
Level
This knob adjusts the overall volume of the
G20D2. Please note that the maximum capacity of
the power amp will be reached at a setting around
1 to 2 o‘clock. You should not use the amplifier at a
higher setting for longer period of time. A violation
of this rule will damage the power amp as well as the
built-in loudspeaker.
Treble, Middle, Bass
These three knobs represent the master equaliza-
tion of the G20D2. Treble controls the amount of
high frequencies in the overall sound, while Midd-
le and Bass are responsible for the mid and low
frequencies.
Level
This knob controls the overall percentage of effects in
the signal. The more you turn this knob clockwise, the
more choosen effect be heard in the overall sound of
the amplifier.
Effects
This knob offers you four different modulation effects
. The choosen effect will be more intense, if you turn
this knob clockwise.
DLY./REV.
This is the delay/reverb section of the amplifier. You
can adjust the delay time / reverb size by turning this
knob clockwise.
Power
Switches the GS2-158D on or off.

In this chapter we will introduce the built-in DSP effects. The programms
available are the most known and used actually.
DIGITAL EFFECTS IN THE G20D2
Chorus
Produces a classical chorus effect. A second sig-
nal with a slight detune and delay is added to the
original signal, which creates a roomy and wide
sound. Reminds a little bit to the sound of a 12-string
guitar.
Flanger
Very modern flanging effect. This program also
adds a second signal to the original sound, which
modulates in pitch.
Phaser
Many years ago, this sound had to produced in a
very complicated procedure. By shifting the phase of
the original signal, single frequencies will be boosted
and erased. This produces a very unique and classic
sound. Funk musicians like to use it very often, but
it can also be set for a small passage inside a rock
song.
Tremolo
This effect became very popular in the 50‘s and 60‘s
, due to the sound of a very big american amplifier
company. The volume modulates between high and
low levels and produces a very slight sound.
Delay
The orginal signal will be repeated with a settable lag
of time. While an echo also produces a room sound,
this effects just repeats the given signal.
Reverb
Produces a room by modulating the original signal in
smaller or bigger reflections. The size is variable as
well as the edge of the reflections.

External Effects
We are convinced that the basic sound of the Fame
G20D2 will suit the demands of most guitar players.
Although, the usage of external effects devices can
provide a variety of new and interesting sounds.
These are divided into:
• Level-related effects are: Compressor, Limiter or
Noise Gate
• Time-based effects are: Delay/Echo, Chorus or
Flanger
• Volume-based effects are: Tremolo, Auto-Volume or
Pan
• Filtering-related effects are: Equalizer, Phaser,
Rotary or Vibe
Due to the fact that the G20D2 does not feature a built-
in fx-loop, all effect devices will always have to be
connected between the guitar and the amplifier’s input.
How to choose the right device
High-quality effects like a vibrato or time-based units like
delays can round up the sound, when placed in front of the
amplifier. But the final sound is depending on the choice of
the specific unit.
A multieffects processor i.e. digitalizes the incoming
signal by using an AD-converter and inverts it after
adding several effects. Depending on the used model,
the sound can be influenced in a negative way.
Expensive units contain very capable converters, which
keep the signal in its original value and even improve the
sound quality.
Analogue units will not harm the signal’s quality, but they
are also limited and normally produce only one overall
sound.
