MB SERIES

Sound Tips

The MB Series has several unique features which, 

if used properly, will obtain the sound you have 

been searching for. 

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. 

Direct Out:

The MB Series provides a low noise, high quality 

balanced  direct  output  for  connection  to  PA  and 

recording  consoles.  A  ground  lift  switch  is 

included  to  remove  hum  and  buzz  when 

connecting  to  equipment  powered  by  a  different 

ground system.

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.
