I've bought a dozen line 6 products over the years and this is the only one that is not even usable for practice; same problems with dropouts every few seconds. I've had wireless systems since the late 80's; this was the most expensive one for me, and by far the worst. Completely unusable, with firmware upgrade, different cable, different everything. It just can't hold a wireless signal for more than 5 seconds. Wow, I vote for a recall. Even if they fixed each unit and sent it back to us, they would still be WAY ahead financially, and would keep customers happy.
