Power the BASS ATTACK - continued
Installing the Battery
Install a standard 9-volt battery by removing the battery door and attaching the battery to
the terminal connector. Fit the battery into the compartment and reinstall the battery door.
Using a AC/DC Power Adapter
You can power the Bass Attack using the optional AC006 power supply available from
your local Hartke dealer. Simply plug the power adapter into the DC inlet and then, plug
the power adapter into a standard 110-volt power outlet.
Control Knobs and Switches
Before you get started you should get familiar with the various control knobs and switches
on the Bass Attack and how they operate. The BASS and TREBLE, as well as the LEVEL
control knobs, are always active regardless of the position of either foot switch. The HAR-
MONICS and BRITE controls are activated by the ON/OFF switch and are engaged when
the red LED is illuminated. The SHAPE control is activated by the SHAPE footswitch and
is engaged when the red LED is illuminated. As you read through the next sections you
will see the power of the Bass Attack and how each layer of control adds to the possibili-
ties.
Using the BASS AND TREBLE Equalizer
The BASS and TREBLE knobs are used to adjust the overall low and high tone of your
bass. The BASS and TREBLE controls are always active but when they are set to the “5”
position they are flat and have no affect on the sound. If you want to add more lows or
highs to your sound, move the BASS or TREBLE control knobs up, and if you want less
low or highs move the respective knob down. Use your ears and experiment with these
knobs to get the sound that’s best for your music. A good place to start is with the BASS,
TREBLE and LEVEL control set to “5”.
