so ive had a good 3 1/2 hours with my pedals, and im getting to know them.

no issues with the ds-1. but im wondering about the digidelay.

when i switch the model (looper, reverse, normal etc...) the thing stops, then comes back on. will this hurt it?

It shouldn't hurt the pedal at all, that just how it was designed. Its not like you are going to reach down and change the settings in the middle of a song. Don't worry about it.
