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

unavailable on any other bass amp. Lower contour

settings are recommended for midrange clarity at

higher playing levels. For the classic 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 response 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 distortion, that sounds great through a

woofer, but horrible through a horn (see biamp 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

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. 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.
