I use G10 that comes with "POD go wireless" option (costs 150.- more).
Compared to cable (tried 3m, several ones, all good), wireless definitely sounds brighter.
As I first made my presets with cable, I wasn't sure whether to consider this as bug or feature.
Ps.
In global settings/ wireless, the option "cable tone" is also set to 3m.
Probably it's story about buffer
