Setup examples
Setup example 2: Ditto Stereo Looper and effects
Place your effects before Ditto Stereo Looper.
This will allow you to create and record different
sounds within the same looping session simply
by switching your effects on and off.
You should also make sure to go from mono ef-
fects (typically distortion and drive pedals) to
stereo effects (modulation, stereo delays etc.).
