INTRODUCTION SPECIFICATIONS
or more than a millennia ago, there was in the Nordic countries a legend
Reidmar Utter
F
about a family consisting of a man named and his three sons, ,
Regin Fafner
and .
One day when Utter was at the river taking a bath in his animal form of an otter, he
was by mistake killed and devoured by the evil god Loki. At this, Reidmar was of
course outraged and demanded a ransom from the Father of all Gods, Odin. The
ransom demanded was Utter's otterskin covered by gold to the last whisker. The
gods saw no other solution than to comply with this and gave Reidmar what he asked
for.
F
afner and Regin became very angry with their father who didn't want to share
his treasure.Finally they decided to kill their father to getthe treasure, and so did.
N
ot long after the two brothers had killed their father, Fafner became so greedy
that he determined to kill his brother Regin to get the treasure for himself.
K
nowing that histreasure would not be safein the family's house, he draggedit to
a cave far from the house. After he had assured himself that all the traces were gone
he transformed himself into a gigantic snakelike dragon and settled down to guard
his treasure.

Congratulations on your choice of the
bass head !EBS Fafner
EBS Fafner II XD
The is the most powerful,
versatile and complete bass head ever built.
With two separate channels, extensive routing
possibilities, built in compressor, tube section,
dual balanced outputs and super powerful EQ
sections, the amp offers an extremely wide
range of sound possibilities.
GETTING STARTED...
1. Carefully unpack the bass head.
2. Check that all knobs are set fully counter
clockwise besides the EQ controls marked
BASS, HI MID, TREBLE, MIDDLE and
EDGE which should be set to mid position.
Make also sure all push switches are set to
their outer positions. Now the EBS Fafners
settings are "zeroed" and ready to be
personalized.
3. Turn on the POWER switch. Wait for
approx. 15 seconds before switching on the
STANDBY switch to allow the tube to
warm up.
4. Plug in your bass. While plucking the
strings as hard as you would during your
hardest playing, gradually increase the
GAIN knob unit the peak LED starts to
flash at peaks.
5. Move over to the VOLUME knob and
adjust for the desired output volume.
BUILDING THE SOUND...
6. The first tonal shaping circuitry are the
Character Filters
next to the GAIN control.
These filters provide for a preshape EQ
prior of further fine tuning of your sound.
7. Enable the filters by pressing the
Active
pushbutton and explore the filter
Filter
section.
8. The clean channel also features the use of a
tube buffer for adding those extra
harmonics by pressing the
Tube Mode
switch.
9. If you need to refine your dynamics, adjust
the COMP/LIMIT knob to your needs.
10.Engage the drive channel by pressing the
Drive Active
button. Now you have full
control of the drive circuitry with its’ EQ.
Turn up the LEVEL to the desired level
compared with the level from the clean
channel.
11.Now, press the button. This mode
Serial
enables you to serial the two channels, so
now you can dial in your drive sound with
the aid of the filters and options of the clean
channel.
This was a brief introduction of .As
EBS Fafner
you go on further in this manual, you will learn
how to use and utilize all of the useful features
that the offers you.
EBS Fafner
GOOD LUCK !

the input and output; the higher ratio the more

gain is achieved with the knob. However,
when this switch is in the outer position, the
frequencies below 350 Hz is bypassed,
producing a warmer distortion without
saturation, allowing the player adding more low
bass than withconventional bass amps. Thebass

SOMETHING ABOUT TUBES…
Although the ECC83 (12AX7) is a long life tube,
it is recommended replacing the tube once a year
to guarantee perfect operation.
In order to replace the tube, please follow the
instruction below:
1) Power off and unplug the amplifier from the
mains.
2) Let the amplifier fully discharge for at least
five (5) minutes.
3) Remove the top cover by removing the four
bolts at the amps left at right side, and the two
bolts on the top cover nexttotherearpanel.
4) Locate the tube at the poweramp board and
carefully remove the tube.
5) Place the new tube in place. Be sure that no
tube pins are damaged.
6) Place the top cover inplace.
Done!
