I had a bad experience stealthing a couple of weeks ago (@ Velvet Revolver).
Hostile (well maybe just overexcited) crowd, knocking into me all the time, yelling shit at me because I wasn't moshing, horribly hot, you get the picture.
Nomad JB3 shut down on me
four times, ruining the recording.
Like I said, environmental problems, most of the time the Nomad is fine. Made a sweet recording of The Stills two days ago, which almost makes up for it
