turn down the bass?
No, not bass, there is too much mids like in FW10 with pressed button "fat" and sound is brighter. The most unpleasant thing is that all presets I opened in FW11 have been deleted after downgrading to FW10 back. Then I updated it to FW11 again and now there is no presets I have opened in downgraded FW10.
At all sound becomes more bright and "righter" but all my old presets with mixed 2 amps+2 cabs sounds very ugly now.
