Setup examples
Setup example 3:
Ditto X2 Looper in an FX loop
If you are using an amp equipped with an FX
Drive
loop, place your modulation effects and Ditto X2
Pedal(s)
Looper in that FX loop. Again: To get the most
out of your setup, place Ditto X2 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.
