GK amplifiers are designed to be flexible and user
friendly for maximum performance. This is
accomplished through these important features:
Active Equalization: There are a wide variety of
equalizers used in instrument amplifiers today.
Passive equalizers are great but only allow you to
cut (signal loss), not boost (signal gain). Graphic
equalizers provide plenty of variation, but are
much better for room equalization. When used with
instruments, they tend to sound unnatural or
synthetic. The equalizer in GK amplifiers is unique
in the industry and reflects over and reflects over 30
years of continuous development and refinement.
We've developed a rotary, four-band, vacuum
tube active equalizer optimized for bass guitar.
The active circuitry allows you to either boost or
cut at a given frequency with greater integrity in
signal reproduction. The treble is a shelving type
control that boosts the high frequencies evenly.
Respectively, the bass is a shelving control that
evenly boosts the low frequencies. The high mid
and low mid are peak (band pass) type controls
with wide Q (bandwidth) patterns which are
much more musical sounding. Each of the four
bands are connected in series, meaning the output of
the first band is fed directly into the input of the next
and so on. This eliminates the rippling or combing
effect that can happen with parallel EQ circuits. The
overall result from all of this is an equalizer that's
flexible, yet easy to use and sounds natural even
at extreme settings.

Shaping: The three-stage shaping filter simplifies
the process of shaping and coloring your tone,
enabling the amplifier to accommodate a wide
variety of playing styles with minimal fuss.
Contour: The Contour is a tube-driven version of
the contour circuit from the RB Series. It adds a
variable control and center frequency select for
precise tone shaping. With the control at zero, the
response is essentially 'flat' (as in no shaping). As
the contour is increased, it scoops out the midrange.
Additionally, it compensates to keep the overall
volume level constant. With it's variable control,
the Contour will accommodate everyone from the
smooth finger style player to the aggressive slap
player.
Deep: The Deep switch extends the low frequency
range of the amplifier to accommodate the extra
low range of the B string on 5 and 6 string basses.
Players of four string basses may also find desirable
results with this filter as well.
Presence: The Presence control adds extra sparkle
on the high end for better clarity and 'openness' in
your tone. This is particularly useful when soloing
or playing chords.
