MANUAL
OUTBOARD BASS PREAMP
SBP-2

This unit oers you the same quality electronics that we
have been building into our basses for over 30 years. Here
are a few tips to help you get maximum performance from
your preamp.
Volume
In most cases the volume control should be set to maximum.
If you are using a small amplier, the use of the preamp might
overload the preamp stage of your amplier causing some
distortion or clipping. In this case, lower the volume control on
the preamp to reduce the gain of the input into your amplier.
If you plan to toggle between an active setting and bypass, use
the volume control to set the desired gain for the active setting.
Treble & Bass
The treble and bass controls are boost only - at response is with
the controls at their complete counterclockwise position. Do not
automatically go to full treble and bass boost - start from at
response and then boost treble and bass as desired. Although
you are free to adjust the settings anyway that pleases you, our
experience is that once you nd the optimal setting for your
bass, you will not have to make frequent adjustments of the tone
controls.
On/O Switch
This footswitch enables you to engage or bypass the active
tone circuit. The green LED lights up when the preamp section
is 'On'. The volume / treble / bass controls do not function in
the 'O' mode. If you want to switch between on and o with
the same bass, use the volume control to adjust the level for the
'On' position. The On/O switch has no eect on the battery life.

The battery is switched on whenever a cord is plugged into the
input jack.
Low Battery LED
The Lo Batt LED will begin to glow when the battery reaches
7.5 volts. We recommend you replace the 9V battery at this
time. To extend battery life, unplug the cord going into the
input jack as the battery is draining anytime that jack is activated.
This is not necessary on short breaks while gigging, but do not
leave the unit plugged in overnight when not being used.
AC Adapter
An input jack for an AC adapter is located on the top of the unit.
The Sadowsky Preamp requires a linear regulated power supply
for quiet operation. For very noise sensitive applications, battery
operation might provide the most quiet operation.
Battery
To change the battery, unscrew the compartment on the bottom
of the unit.
