I do have the MKI versions of Musiqual EQs, not downloaded the free update to MKII yet, I do have the others three super plugin as well, I’ve never really use any of this bundle, the Red, Blue, Green Musiqual names don’t mean much and don’t help you remember which one sounds like what, so I end up using something I know instead, although the new MKII version look much improved with new features like a harmonic distortion, compressor, so I'll probably give them a try.
It would be much better if they just combined the there plugins into one plugin, that would make a really usable single plugin, rather than let me try the blue, now let me drag the red and try, etc.
If you wanted some plugins to add some colour, analog flavour, etc., it’s good value, as long as you get some use out of them.
One plus with MIA Laboratories is they haven't charged existing MKI plugin owners for the recent updates to MKII plugins, so props to them for that.
I’ve found the MIA Laboratories Pi and Phi MkII EQ to be more useful (it’s also on sale, and on JRR Shop and AudioDeluxe), the Pi and Phi MkII EQ is unusual EQ / enhancer that works really well, but one plugin that you need to try, and decide for yourself.
