Hi, i have also been having these drop out very frequently over the last few months of playing shows, i have updated the firmware to the latest last week and had it drop out yesterday. I had to borrow a G30 for the set. Other then that it has been an amazing unit.
I use it on my strap about half way up, also our bass player has a G90, i have heard they can interfere with G70's? But when the G90 is switched off i still experience the drop outs.
Thank you.
