That's a great update
@ucnick!
I would guess the big difference between the 10 and 12 would be the volume more than the overall tone. But these seem really capable of high volumes.
It's hard to describe how an ""FRFR"" can sound so much like a real amp while using a cab but that must be part of whatever design they did. Maybe the cab design it self. It really does remind me of my old band (25 years ago at this point!) where both guitarists had Fender Hot Rod Devilles. Big loud clean tube amps with big speaker cabs.
