Sound Tips
The MB 800 has several unique features which, if
used properly, will help you obtain the sound you
have been searching for.
Discreet Preamp:
The MB800 features a completely discreet FET
(field effect transistor) driven preamp. The same
FET technology used to create the legendary boost
(G.I.V.E.) circuit found in all GK amplifiers for
over 30 years is used in every stage of the MB800
preamp. Using FET devices with the gate biased in
a way that emphasizes the optimum harmonic
content of the signal to drive the GK four band
active EQ, Contour and Gain allows the MB800 to
transition seamlessly from a full, warm, clean tone
to full on GK growl.
The Equalizer:
The Equalizer is used to fine tune your sound.
When adjusting making adjustments, do it just 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 and provides you with
a large variety of great sounds unique to GK.
Contour:
Increasing the Contour level will scoop out
midrange frequencies while boosting the highs and
lows. The sound, once again, is unique to GK and
available on any other bass amp. Lower contour
settings are recommended for midrange clarity at
higher playing levels.
Gain B/ Level B:
Turning up the Gain B control will add a little
growl to your tone by adding a small amount of
ever order harmonic distortion. This is an
unmistakable GK trade mark sound that you will
surely grow to appreciate. Raising the Boost while
lowering Level B will add more growl while
MB 800
keeping the sound level the same. You can use
Level B to increase or lower the overall output
volume when switching the Gain B on via the front
panel or from the included foot switch. With either
Gain A or Gain B, the cleanest sound is obtained
with master volume settings at approximately 3
o'clock.
Direct Out:
The MB Series provides a low noise, high quality
balanced direct output 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 the input stage providing a low noise
output superior to external direct boxes and
impedance transformers. In the "Pre" position, the
direct output signal is only effected by the Input
Volume, -10db Pad and Mute. This allows you to
adjust your tone and volume on stage without
changing the Direct Output signal level and
confusing your sound man. Changing the Pre/Post
EQ switch to "Post" (in), sends the "GK Sound"
(EQ settings etc.) and preamp response to the
Direct Out jack. This gives you complete control
over the Direct Out's tone and volume.
Limiter:
When the limiter is engaged it prevents the power
amp from distorting. It is recommended that this
feature is used during high volume situations.
