I've got the same issue I think, also with the GSG. It's very dark to the point it doesn't seem intentional.
clean6 -- did you have to reinstall the firmware update to resolve it or was it some other trick? Thanks.
EDIT: I've updated to the 2.02 firmware and it sounds the same. SOOO muddy compared to the same manual settings for the other channel (litigator). Can't believe that is how it is supposed to sound, but I might be wrong.
