Sound Tips - Gallien-Krueger Backline Series Owner's Manual

Sound Tips

The Backline Series has several unique features which, if
used properly, will obtain that sound you have been
searching for.
The Equalizer:
The Equalizer is used to fine tune your sound. When
adjusting it, do it a little at a time. These are active
circuits, and small changes can make a big difference in
your sound. With a little experimentation you will find
that this equalizer is very easy to use, never sounds weird
and provides you with a large variety of great sounds,
unique to GK.
Contour:
Increasing the Contour level will scoop out mid-range
frequencies while boosting the highs and lows. The
sound, once again, is unique to GK and unavailable on
any other Bass amp. Lower contour settings are recom-
mended for midrange clarity at higher playing levels. For
800RB voicing, set the contour knob either
on 0 or 10 .
Overdrive:
The Overdrive channel allows you to create entirely new
bass sounds. Modern bass players are just beginning to
experiment with distortion and now you can too. Turning
the gain control within its range will give you everything
from a funky blues sound all the way to full saturation
and sustain.
Boost/Master:
Turning up the Boost control, will add a little growl to
your tone. This is an unmistakable GK trademark sound,
that you will grow to appreciate. Raising the Boost while
lowering the Master will add more growl while keeping the
sound level the same. Growl is actually a small amount
of even order harmonic distortion, that sounds great
through a woofer. For most playing situations, the Master
is set between 12 & 3 o'clock. The cleanest sound is
obtained by setting the Master at 12 o'clock, and going
above 3 o'clock for maximum power situations.

Direct Out:
The Backline Series provides a low noise, high quality
balanced direct out for connection to PA and recording
consoles. With the Pre/Post EQ switch set to "Pre"
(Out), the direct output signal is fed directly from our
low noise, high headroom, FET input stage providing a
low noise output superior to external direct boxes and
impedance transformers. The Direct Output signal is
only effected by the -10dB Pad, and Tuning Mute
controls. This allows you to adjust your tone and
volume on stage without changing the Direct Out signal
level and confusing your sound man.
Changing the Pre/Post EQ switch to "Post" (In), sends
the "GK sound" and preamp response to the Direct Out
jack. This gives you complete control over the Direct
Out's tone and volume. In addition, a Ground (Gnd)
Lift switch is included to remove hum and buzz when
connecting to equipment powered by a different ground
system.
