Peavey Dyna-Bass

and bypasses the internal preamp. This allows nor¬
mal (passive) operation of the Dyna-Bass. In the pas¬
sive mode, the Volume and Blend controlsareopera-
tional and the High Control is converted to a standard
high rolloff tone control. NOTE: If the Bypass Switch
is operated when signal is present, an audible "pop"
may occur. This is due to the rapid change in signal
level sent to the input of the bass guitar amplifier. The
down position Is active and engages the Dyna-Bass
preamp with its active tone controls.
7. Preamp Input Control. This is a screwdriver adjusted
control and is accessible through a small hole in the
control cover plate on the back of the Dyna-Bass.
This control sets the amount of signal gain available,
and should be adjusted so the Dyna-Bass will not
overdrive or distort the input of your bass guitar
amplifier. Clockwise ad;ustments Increase the out¬
puts and counterclockwise adjustments decrease the
output. Those who have a heavy picking style or who
play heavy ‘'pep'' bass may need to use the Low Gain
or *2 Input on their bass amplifier.
8. Battery. The Dyna-Bass preamplifier is powered by a
9 volt transistor radio battery (not included) which is
access ibis after the control cover plate has beer
removed from the back of the instrument. NOTE.
Heavy duty or alkaline batteriesare recommended for
reliability and longest battery life. Low battery voltage
will be indicated by fuzzy or distorted sound, espe¬
cially with higher tone and volume settings. It is
recommended the battery be changed every 80 to 100
hrs. of use, or every 6 months, to help ensure a battery
doesn’t leak and damage the instrument. NOTE: Pea-
vey Electronics assumes no responsibility for dam¬
age resulting from a leaking or defective battery
Power is supplied to the preamp when a standard
(mono) guitar cable is plugged into the instrument, a
stereo cable will not work. It is recommended that the
cable first be plugged into the Dyna-Bass. then into
the bass amplifier input. To ensure longest battery
life, be sure to unplug the cable from the Dyna-Bass
when not in use.
Adjustments:
Your instrument has been carefully adjusted for accu¬
rate intonation and playing ease at the Peavey factory.
However, your playing style or playing requirements may
necessitate additional adjustments at sometime in the
future. These adjustments should be made by your
Peavey dealer. However, with a little care and by adhering
closely to the following instructions, you may attempt
these adjustments yourself.
CAUTION:
PLEASEREAD AND UNDERSTAND THE INSTRUC¬
TIONS THOROUGHLY BEFORE ATTEMPTING ANY
ADJUSTMENTS!
Adjusting Torsion Rod:
To set the "straightness" or "relief" of the neck, a
Peavey tersion rod wrench No. 75031001 must be used
(available from a Peavey Accessory Center).
1. T une the instrument to standard (A-440) pitch
2. Check for clearance between the strings (1 through
4) and the first fret IMPORTANT: Use an accurate
ruler or similar gauge for this measurement
3. This clearance should be no less than 1/32" and no
more than 1 / 16 " at the first fret.
4. Check for clearance between the strings and the
twelfth fret.
5. This clearance should be no less than 1/16” and no
more 1/4" at the twelfth fret.
6. To increase clearance, loosen (counterclockwise)
torsion rod nut. To decrease clearance, tighten
(clockwise) the torsion rod nut. (The torsion rod nut
is located underneath the plastic cover plate on the
head stock.)
CAUTION:
IT IS NOT USUALLY NECESSARY TO ROTATE
THE TORSION ROD NUT MORE THAN ONE FULL
TURN IN EITHER DIRECTION. ONE-OUARTER
TO ONE-HALF TURN IS NORMALLY SUFFICIENT
TO MAKE MOST ADJUSTMENTS. EXCESSIVE ROTA¬
TION MAY CAUSE DAMAGE TO THE NECK AND
TORSION ROD. IF EXCESSIVE FORCE ISNECES-
SARYTO ROTATE THE TORSION ROD NUT, YOU
SHOULD CONSULT YOUR PEAVEY DEALER OR
THE PEAVEY FACTORY BEFORE ANY FURTHER
ADJUSTMENT IS MADE.
7 Repeat steps 1 through 6 until proper clearance has
beer reached
Neck Tilt:
The neck tilt adjustment works in conjunction with the
bridge height adjustment to set the overall string playing
height. This adiustment should be used whenever possi¬
ble to set string height, rather than the bridge height
adjustment.
1. Relieve string tension slightly by detuning the instru¬
ment (approximately 1 to 2 full steps).
2. Loosen two neck screws closest to headstock (approxi¬
mately 1 turn).
3. Loosen remaining two neck screws closest to the
bridge (approximately 2 turns).
4. String height may now be adjusted with the neck tilt
screw, which is located inside the small hole in the
neck plate. A Ye" Allen wrench is used to make this
adjustment. Turning the screw clockwise raises the
end of the neck, thus bringing the strings closer to the
fingerboard.
NOTE:
STRING HEIGHT SHOULD BE ADJUSTEDTO FIT
YOUR OWN PARTICULAR PLAYING STYLE. IT
SHOULD BE NOTED THAT SETTING THE STRING
HEIGHT TOO LOW WILL RESULT IN EXCESSIVE
STRING BUZZ AND RATTLE, ESPECIALLY WITH
A “HEAVY" PLAYING TECHNIQUE. EXCESSIVELY
HIGH ACTION WILL RESULT IN INTONATION
PROBLEMS AND DECREASED PLAYABILITY.
5. After adjustment, securely tighten all four neck atta¬
ching screws, being carefu: to balance the torque on
all four screws equally.
6 Tune the guitar to standard pitch. Check strings lor
correct height and playability. If necessary, repeat
steps 1 through 5 until action is correct.
String Spacing Adjustment:
The fully-articulated Schalier bridge allows for maxi¬
mum flexibility when adjusting spacing between strings
To adjust, loosen string, then rotate saddle roller to
desired position Retune string NOTE If bass is eouipped
with optional Kahler tremolo, refer to supplied Kahler
tremolo manual for adjustments.
