The looper works fine the first days, when it's fresh electronics, but after couple of days starts producing clicks, pops and volume drops, probably due a bad engineering and/or software part, managing the looper memory chips. It's a well known issue, that have been reported hundreds of time in the T.C. forums, and it's still there since firmware 1.0. Also the unit takes ages to boot and some times goes stuck while booting and you need to unplug and plug again.
I bought the pedal hoping to find a good one, but after couple of days I started getting exactly those problems that many other guys are getting and reporting, without having proper attention and support from the T.C. company.
It's a shame really, because on paper would be a great easy peasy looper, for almost any genre, but these bugs are making this a no-way for live performance (totally unreliable) .
I returned the pedal and I think this is my first and last TC looper I'll buy.
