BUILDING THE SOUND...

Your EBS Classic450 features an en-
hanced tone shaping circuit that will enable
you to create a variety of bass sounds.

6.

The filters are basically the boost/cut design.
This means that the level controls marked
with + and - signs, either boost or cuts the
selected frequency band. Further, the two
MID sections have got frequency controls for
precise adjustment of the midrange.

7. Gradually increase or decrease the level and

vary the frequency of the various filter sec­tions. Notice how the sound is affected.

8. Repeat as above by trying out the preshape

filter Character.

9. Proceed to the Drive knob. This control

adjusts the overdrive and can be seen as
moderate up to 12 o’clock, after that point
you could get highly distorted sounds.

10. For further reference, check out the sample

sound setting on the last page of this manual.

This was a brief tutorial of EBS Classic450.
As you go on further in this manual, you
will learn how to use and utilize all of the
useful features that the EBS Classic450 off­ers you.

GOOD LUCK!

The EBS Classic450 is a solid-state
amplifier head, extremely easy to dial-in. It
is designed to match the EBS ClassicLine
cabinets in all styles and situations. The
sound of the Classic 450 amp is a
combination of vintage bass sound and the
transparent ’EBS’ sound that let your
playing style and the character of your
instrument speak. Versatility is provided by
a carefully designed EQ section with very
creative dual midrange sections. The
boosted drive control adds everything from
subtle, vintage overdrive to mean, crushing
distortion – without loosing the low-end.
These brief tutorials will help you to
become acquainted with some of the fea­tures of the EBS Classic450.

GETTING STARTED...

1. Carefully unpack the bass head.

2. Check that the Volume and Drive controls

are set to zero, fully counter clockwise. Set
all the other controls to mid position and
make sure that the switch marked Character
is in its’ outer position. Now the EBS
CL450’s settings are "zeroed" and ready to
be personalized.

3. Power up the head and plug in your bass.

4. While plucking the strings as hard as you

would during your hardest playing, adjust the
GAIN knob until the PEAK led starts to flash
only at highest peaks.

5. Move over to the VOLUME knob and adjust

for the desired output volume.
