Hi, just sharing my experiences. I've been using the G70 for a few months, for around 15 gigs. I use it on my pedal board on the floor, powered by USB (for some reason I get a ground loop hum using it with my Fuel Tank). I wear the tx on my strap, behind my back. The venues I've used it in include pubs, halls, community centres and outdoor on festival stages. I'm a bass player btw.
So - having spent a good sum on this unit, I was worried when I read the comments above. I thought I heard a couple of drops when I first got the system, and occasionally I think I hear them... but so far all my gigs must have actually been drop-free... because last night I had three definitive drop-outs (at least that was how many I counted; it may have dropped out when I wasn't playing and I didn't notice) of around 30ms – long enough for me to notice (but no-one else in the band heard them. Typical). For the second set I did a channel scan – and it chose the channel I was already on. But there were no more drop-outs. So I think that's a regular procedure now, to be sure. Also, in the second set, I jumped off stage for part of the set (it was a tall stage), and then had to run round backstage to get back on again, while playing. Now I think about it, the sound didn't drop then either. So hopefully we'll be ok. By the way, I bought some rechargeable 2300mah batteries and not only to they last four times as long, they're, er, rechargeable too.
