Sadowsky SBP-1 - Volume Control Usage; Treble and Bass Tone Shaping; On;Off Footswitch Operation

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. All other functions (Dl, tuner out, mute) work 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.
