I'm am really wanting to get a looper (for mainly practicing purposes) and have found that these two are the most promising for their price range (under $300). Which one would be more useful and easier to use? I'm leaning more towards the Boss RC-20 because I might be getting the new BassPODxt Live and that includes alot of delay effects. What are the pros and cons of each? This will be used 99% for practicing. And are there any other loopers <$300 that would meet my criteria better?
