BTW, phyrexia's comment on the MC90 not "hitting you" with authority, I'll agree with to a point. In a larger cab (like a MKIV widebody or a DC5 which is the same cab), the MC90 shines! I can only suppose the same is true with the larger (i.e current-production) Mesa 112 cabs ...the MC90 would likely sound better in these than in the smaller MK cabs.
FWIW, I have an open-back 112 cab that matches my Thiele cab (ya know the one, it fits perfectly under the short-chassis head). This one with the MC90 sounds very different from the my MC90 in the DC5 (again, a considerably larger cab). That "boxy" and mid-focused feel and lacking bottom punch is exacerbated by the smaller interior volume. Which is why I prefer the MC90 in my DC5 combo, but want to replace the MC90 in my 112 cab with an EVM or EV Force (which I haven't heard personally, but seems to get great press). Hope that makes sense
