V30 comparison: Mesa OS vs Framus Dragon cab using SM57, E906

Like the Dragon with the E906, just enough fizz for liveliness and enough upper mid grind to cut (57 which sounded too scooped).

Exactly my thoughts. I like a bit of fizz in a guitartone, as long as it's not earpiercing.
On a sidenote, I'm starting to notice that I prefer that E906 over other mics in shoot-outs a lot. I should really try that mic myself some time.
 
The framus more present to me on the single notes which i like, so i would take the framus, its less clouded.
