Sound Tips

The 2001RB has several unique features which, if

used properly, will obtain that sound that's in the

back of your head.

The Equalizer:

The Equalizer is used to fine tune your sound. When

adjusting it, 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, 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 unavail-

able on any other Bass amp. Lower contour settings

are recommended for midrange clarity at higher

playing levels. For 800RB voicing, set the contour

control either on 0 or 10 (Off, On on 800RB).

String Bass:

The way a Bass amp deals with the instrument low string

is a critical part of its sound. In fact, a five string

instrument requires an entirely different low end re-

sponse than a four string instrument. No equalizer can

make the necessary adjustments to accommodate both.

However, the String Bass button on the 2001RB does

just that. When it is out, the 2001RB is voiced like the

800RB . Push it in and the 2001RB is voiced for five

string instruments. For some playing styles you may

want it in, even with a four string instrument.

Boost/Master:

Turning up the Boost control, will add a little growl to

your tone. This is an unmistakable GK trade mark

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 distor-

tion, that sounds great through a woofer, but horrible

through a horn (see Bi-Amp solution below). For

most playing situations, the Master is set between 12 &

3 o'clock. The cleanest sound is obtained by setting

the Master above 12 o'clock, and going above 3

o'clock for maximum power situations.

Direct Out:

The 2001RB provides a low noise, high quality

balanced direct out for connection to PA and record-

ing 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. In addition, this output

is calibrated for 1.0V (0 dBV) output and can be

adjusted to unity gain (instrument level) by adjusting

the Level control to -15 dB (U) . With the switch in

the Pre position, the Direct Output signal is only

effected by the Level, -10dB Pad, and Tuning Mute

controls. 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" 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.
