2001RB & 2001RBP
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 abig difference in
yoursound. With a little experimentation you willfind
that this equalizer is very easy to use, never sounds weird
and provides you with a large variety of great sounds,
uniquetoGK.
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:
Theway a Bass ampdeals with the instrument lowstring
is a critical part of its sound. In fact, a five string
instrumentrequires an entirely different lowend re-
sponse than a four string instrument. No equalizer can
makethenecessaryadjustments toaccommodateboth.
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.
Sound Tips
Boost/Master:
Turning up the Boost control, will add a little growl to
yourtone. This is an unmistakableGK trade mark
sound,that you will grow to appreciate. Raisingthe
Boostwhile lowering theMaster willadd more growl
while keeping the sound level the same. Growl is
actuallya small amount of evenorder harmonic distor-
tion,thatsounds greatthrough awoofer,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.
