Setup examples
Setup example 3: Ditto Stereo Looper in an FX loop
If you are using an amp or a mixer with a stereo
FX loop, place your modulation effects and Dit-
to Stereo Looper in that FX loop. Again: To get
the most out of your setup, place Ditto Stereo
Looper at the end of the FX loop. This gives you
the flexibility to add parts with or without signal
processing by simply switching effects on and
off as required.
