I purchased the G70 for it's multiple inputs and planned to use it for guitar & harmonica. No problems with guitar...works great. When using with astatic harmonica bullet style mic, the signal seems to be clipping when playing hard. I discussed with Line 6 service and they agree it's a signal level issue, requiring some type of attenuation, yet I want to keep the connections between mic and transmitter to a minimum. No one seems to make a 1/4" inline attenuator. I ordered a custom one and will see if it works, but looking for any other ideas or suggestions. Still hardwired in Orlando. :(
