I have the bigger DigiTech with separate three button footswitch, don't know the model, sounds fantastic and has all the bells and whistles, stores, sends, imports, switches tracks blah bla. I never use it, takes too long to relearn it. Younger guys seem better at operating these. I want a simple one now like a Ditto or Ammoon, keep it simple for practice jams. I figure if I really need to start massive layering it is time to get out the multi track. Those do everything and if you pick the right model they are super simple to use. Pretty inexpensive these days too.
