tc electronic Ditto X2 Looper

I've been using this looper for the last few years in live settings. When it works it's great, simple and sounds great. The problems come when it suddenly freezes live. Then there is almost nothing you can do. I have a back-up in my bag at all times. I just bought a new one and it froze up, never to return, in the first few weeks of use. The pedal is sturdy and made strong but the software is not stable. It's a great looper for home use but if you use it live have a back-up, or maybe just buy a better looper pedal. TC Electronics does some great things but high quality is not their first prority. That being said I still use this pedal because it's simple and when it works it's just what I need. :)
