CT4-B PRE-AMP
Your guitar may be fitted with any of the following pre-amps.
Please refer to the separate pre-amp information for operation
and specifications.
CT-4B pre-amp features
■
The CT4B pre-amp is designed for ease of use and purity of
tone. The CT4B consists of 3 bands of graphic EQ tone
control, a volume control slider and a built-in chromatic tuner.
■
The 3 band EQ provides control over the bass (LOW),
midrange (MID) and treble (HIGH) frequency response.
With the sliders set at the midpoint (0) the electric signal
from the guitar is evenly balanced across the frequency
range. The desired tone is then dialed in by using the sliders
to add or subtract frequency response as desired.
Each frequency control slider will raise or lower the band
response by +/-5db.
■
The volume slider adjusts the output volume of the pre-amp.
■
The convenient built-in chromatic tuner is extremely accurate
and very easy to use. The tuner is activated by pressing the
TUNER POWER button. To tune your instrument, simply pluck
any open string. The tuner will then display the name of the
note that has the closest frequency of the string played.
The amount of deviation from the note (higher or lower) is
displayed by red arrows indicating sharp or flat.
When only the green center light illuminates, the note indicated
in red has reached precise tuning. When the guitar is unplugged,
the TUNER POWER switch acts as on and off. Your CT4B tuner
is also capable of being calibrated to frequencies other than
standard A440.
When the PITCH button is pressed, the frequency that is currently
set will be shown by a flashing red light above the frequency
number. While the reference light is flashing, press the Pitch
repeatedly to set the desired reference pitch.
With each press of the button, the reference pitch will increase
by 1Hz increments from 440Hz to 445Hz. Once the pitch has
reached 445Hz, the next press will decrease the pitch to 438Hz.
When the button operation is stopped, the reference pitch is set
and the tuner will stand by for tuning.
