Same thing,
My door on the G30 is broken and I have had to resort to tape at my last gig as I run the p.a. and use the wireless to spot check
the levels in smaller venues.
I also see the smallest stress type of crack on the chassis near the door.
The wireless itself works fine and I love that I can keep the receiver on my pedal board.
I am a line 6 junky but can't believe they have overlooked this.
It seems to happen often as I have googled and read up.
Please help a faithful customer out line 6.
