Yes, it's all good for me.
How are you determining "what it is?" In your view, is management at MM out to pick our pockets with these? I don't think so.
...And "what is is" isn't less. The form-fit bag that they're having Mono make for them IMO is actually a lot nicer and more practical to me than the SKB-type HSC that came with both of my Sterlings, (one had a "meltdown") ; even the G&G Alligator case that they sent me for my Bongo.
That's because 95% of the time I prefer a gig bag, seeing as I work locally and transport myself and my bass in my car. If my gear were being loaded onto a bus, van or plane then I would use a case.
My bet is that the vast majority of MusicMan instrument buyers are in the same situation as me, by a HUGE margin. (Not that they/you are not entitled to want to use a HSC if they wish to!
