Using Dual Mode With An External Effects Unit

Please remember that when "Dual Mode" is engaged, the "clean" channel is always on the LEFT side, and the "wet" channel
is always on the RIGHT.
The key function of Dual Mode is to allow the user separation between "clean" and "wet" sounds. But it also allows for differ-
ent external signal processing on each channel. In other words, it is possible to utilize two different external effect devices
independently. Simply route the left effect send to one device and return it to the Left Effects Return jack. Then repeat the
process for the right side using a different device. This allows you to process the "clean/left" signal with one effect and the
"wet/right" signal with a different effect.
Many so-called "stereo" external effects devices sum their inputs to a mono signal and then convert the mono signal into
stereo at their outputs. The Mo' Bass External Effects Loop is a TRUE stereo loop. To achieve true stereo effect send and
return, be aware that your external effects device must process signals in TRUE stereo. Otherwise, your left and right effects
returns will process both "clean/left" and "wet/right" signals from the Mo' Bass and the two channels' effects will bleed into
each other.

Stereo Master Volume Controls

The Stereo Master Volume Controls adjust the individual volumes of the internal power amplifiers. For both controls, fully
counter-clockwise ('0') is minimum, while fully clockwise is maximum. As mentioned previously in the "Getting Started"
section of the manual, both controls are active at all times. Whether you're in Single Channel Mode or Dual Mode for the
preamp/effects, or Stereo or Bridged/Mono mode for the power amp, both controls are always independently active.
This is your last chance in the signal path to adjust levels. In addition to setting the overall output level of the entire unit, you
can use the Stereo Master Volume Controls to:
a) Balance two speaker cabinets of different impedance when running in stereo
b) Balance the clean/left and wet/right channels when in Dual Mode, regardless of how you are running the power amps
c) Balance master levels when using two different external effects units in the external loop
For most applications, however, you can set the Left and Right Master Volume Controls at equal levels and adjust to taste for
overall volume.

Stereo Headphones Jack

By inserting a set of stereo headphones into this jack, you can satisfy your urge to play through the Mo' Bass at all hours of
the night without disturbing your neighbors - or even hooking up speaker cabinets. The headphone volume level is adjusted
by the Stereo Master Volume Controls.
We suggest you begin with the Master Volume full off (counterclockwise). Then slowly bring the volume up to your desired
level. If you hear some distortion in your headphones that is not present with the speakers on, turn down the Master Volume
Controls. You're probably exceeding the capability of your headphones and could ruin them. Be especially carefully when
engaging effects that boost level, like Overdrive. The recommended impedance for your headphones is 32 ohms, but results
can differ, as the efficiency ratings of the drivers contained in headphones vary greatly.
Here's a hint: try running the Mo' Bass in Dual Mode with some effects engaged while using a nice set of stereo phones. We
like it.
