I never had a problem when I had an XT Live, however, if you can afford one, buy a HD500x instead (and then get the HD Bass pack for it), well worth it.
I had an XT bean since they came out, and got the Live to replace a Zoom B3, but found it to be not that great for the effects. The Amp/Cab sims I felt were better than the B3's, but the effects didn't really shine through from my perspective. Hunted around for an appropriate (and affordable) alternative, and ended up getting the HD500x. Been using that for over 3 years now, and very happy with the results.
Second hand versions are a great buy, as they do tend to have been looked after.
Another alternative would be the HX Stomp, but that's significantly more than a second hand HD500X.
