EQ's Default, Should be Flat..
This is straight forward enough. I've had to save my own (Flat) preset.
Also a default boost in the Bass (75Hz) area may not be good/pleasant for all ears/speakers.
Personally i would put that under bugs for not being flat (havent checked it) and a request to allow default preset for all the effects, as simple as saving a preset called 'default' for each one would do it.
Yep! Surprised there were almost no presets for anything within BM3..
Expected behaviour or bug, well oversight rather than bug
