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 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

MB 800

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.
