I've been working through the same issues as everyone else. In my case, I had a run of success in the beginning. Like everyone else though, I've had bad connectivity and it became unuseable in my last three situations. One gig at a bar, one gig at a golf club house, and one rehearsal at my typical band space. So if the wifi router strength is the issue, how can we even control that and more appropriately, why should we have to? What doesn't make sense either is I was told from Line 6 support that the G70 has better connectivity than the G50 I owned. I never had one interference or connectivity issue, ever, using the G50. Granted I didn't use the G50 for every gig and I only gig about 10-12 times a year, but the G70 has been horribly unpredictable. So that's the main point here. There are tons of people having serious issues with this product and it's not stable enough for paid gigs, IMO.
Besides going back to a G50, what are some other options that are dependable and sound good. I will give the G70 kudos on sound quality. I don't care as much about the additional feature set. I want sound and connectivity. Anyone have any thoughts on a pro solution that works well?
