Hello. Thank you for your answer. I have got one pedal now. It does not sound good if I use both PocketPOD and the Boss DS-1 at the same time.

If I use a "clean" preset and press my "distortion"-pedal it will sound like the guitar-intro-sound on (but a little bit heavier) "Satisfaction" (I say that to explain the sound )

What can I do to make it work like normal? It´s something with the settings on my PocketPOD, becuase the pedal works fine without the PocketPOD and vice versa...
