This has proven very useful on other platforms.
It will allow you to keep your patches in tact while balancing for different room acoustics, or when you use different FRFR rigs.
I use a Xitone cab most of the time which I would say is extremely flat in response but a bit large/heavy to tote around. I also use a very compact Headrush 108 to lighten my load, however it is bass heavy. having a Global EQ allows me to make a simple adjustment to compensate and all my patches can be left as they are.
