Am I better to get a separate looper pedal for live performance instead of trying to use the Timeline looper? I can get the small Boss looper pedal for between $125-$150, and the double one for between $150-$200. About the same as the dedicated midi pedal. I am not limiting myself to just Boss. Could also get the JamMan pedals... Any thoughts? If the separate looper is better, which one of those is best?
