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 ﬁ ne 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 ﬁ nd

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 fre-

quencies 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 800RB voic-

ing, 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 ﬁ ve string instru-

ment 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 ﬁ ve 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 Bi-Amp solu-

tion 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 trans-

formers. In addition, this output is calibrated for 1.0V (0

dBV) output and can be adjusted to unity gain (instru-

ment 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 Tun-

ing 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 connect-
