I have used the G50 for years & loved it it! Flawless tone & performance! No drop outs or issues of any kind ever! Upgraded to the G70 a month ago. The first unit I received had various problems including a non-functioning button on the unit & a broken AC wall wart and also lots of drop outs. I returned it....got a replacement & all of the issues were resolved except for the dropouts. Probably 3-5 dropouts during a 3-60 minute sets evening. The dropouts last no longer than a second each but are very disruptive & unacceptable! Really disappointed because I was really digging all of the upgrades. I am a 30 year veteran of gigging, recording & tons of gear experience so I don't think it is user or setup error. Bummer! Hoping there is a firmware fix or something that will resolve this issue before I have to look to other models of wireless systems.
