BOOST:
Another valuable feature is the selectable
BOOST that allows you to further shape the EQ curve to
your needs. With the lower cover removed, this black DIP
switch is located at the edge of the battery compartment on
the lowest circuit board’s lower right corner (facing the bot-
tom of the unit and the knobs away from you). Its lever is
flush with the circuit board and a slight cutout on the board
further identifies it. You may pull the Battery out for easier
access to this switch.
Remove the four Phillips-head screws on the Bottom Lid to
access the switch - just as you would to replace the battery.
Setting the switch to the RIGHT / OUTSIDE (viewed from
bottom / knobs away from you) BOOSTS (adds) gain and
low end. The unit is shipped from our shop set this way -
BOOST engaged. Setting the switch to the LEFT removes
the BOOST voice providing a more balanced response.
Heavy, high gain sounds usually benefit from the BOOST
position engaged. Low to medium gain sounds can work
with both positions, but often benefit from the more tapered
and balanced low end of the non-BOOST or normal posi-
tion.
NOTE: The unit is shipped from the Factory set to the
BOOST position. To remove the BOOST and its increased
low end, remove the Bottom Lid and flip the tiny black DIP
switch on the lower right edge of the circuit board to the
LEFT (NORMAL) position.
NOTE: REPLACE THE BOTTOM LID after setting the
BOOST switch before using the unit. Some electronic parts
inside are static sensitive and can be damaged from even
a small static charge from a carpet or other soft surfaces.
Always replace the bottom lid after battery replacement or
switch adjustment before the unit is used. To do an A/B
comparison with the bottom removed – play the unit upside
down. DO NOT SET THE UNIT ON A METAL (or any)
SURFACE WITH THE BOTTOM REMOVED!
AC POWER:
This standard female DC Receptacle on
the pedal is the External Power Supply Jack and it accepts
the male plug from a standard 9-Volt DC“ wall-wart” power
supply. When installing your unit into a pedal board utilizing
a universal power supply (multi-output pedal board power
supplies), connect the external power source here. SEE
WARNING BELOW!
NOTE: The External DC Power Supply is Not Included.
WARNING!!! To avoid immediate damage to your unit and
the voiding of your warranty, the External Power Supply
MUST be 9VDC with a NEGATIVE CENTER plug polarity
and a jack size of 2.1mm x 5.5mm. Do NOT connect a (Volt
AC Power Supply to the EXT Power Jack!
The internal battery is automatically disconnected by a
switching element in the External DC Receptacle on the
pedal. However, if you know you will not be using battery
power for an extended period – for example, if you are
mounting the unit to your pedal board permanently - it is
wise to remove the battery to avoid possible damage from
long-term battery corrosion.
INTERNAL BATTERY:
This unit can operate on either
a 9-Volt battery or a standard 9-Volt “wall-wart” DC power
supply. The unit is shipped from the Factory with a long-life
9-Volt Battery to facilitate easier trial demonstration in a
music store environment.
NOTE: The internal battery is switched to an “ON” state
(drawing voltage) by a switching element in the INPUT jack.
SAMPLE SETTINGS: SAMPLE SETTINGS:
TIGHT CRUNCH LIQUID SOLO
MODERN DRIVE HEAVY GAIN
Disconnect the cable from the ¼” INPUT jack whenever the
unit is not in use to prolong battery life.
BATTERY REPLACEMENT:
To access the 9-Volt bat-
tery for inspection, replacement or removal; make sure
the External Power Jack is disconnected, remove the four
Phillips-head screws from the four corners of the bottom lid
and remove it. Note the orientation/direction of the battery
and terminals and replace it in the same position.
NOTE: Any type of 9-Volt battery will work in this device if
it is fully charged and functional. Carbon Zinc, Alkaline or
even Nickel Cadmium Rechargeable type batteries are all
acceptable replacements. Some pedal aficionados prefer
the “sweetness” they claim to hear from standard Carbon
Zinc type batteries, but you will have to decide what type
best serves your needs.
