In what way would that be good? Or what does this mean? If it changes the frequency response, it may be better sometimes but would be worse at other times. What does a conventional guitar cab sound like? If you have an impulse of that cab, this would then make it sound LESS like a conventional cab
It's hard to describe, and maybe this is why Fender got it so right, IMO:
It doesn't seem like they were going for "the true "FRFR" sound of whatever IR you're using", it seems like they were going for, "even though you are using a complete chain, including an IR and a mic, it's going to come out sounding like that, AND Amp where I'm at
TM, at the same time", lol.
Yeah, it's really not flat at all at default settings. You have to cut bass and boost mids and treble to flatten it out and even then, it's not really flat.
And yet... it's still enjoyable to play.
Truth
Saying it sounds more like a cab is basically saying that it evokes more of the feeling of the IR you're using than some other FRFRs. Like when I load up a 4x12 cab IR it doesn't sound as much like a 4x12 in a cardboard box and sounds more like a 4x12 is supposed to.
Truth.
A QSC K12.2, for example, is LOUD, and reproduces sound well, and isn't cheap, but even that speaker, where it usually is, onstage, seems like it has a small dispersion pattern, (or we just end up standing too close to them), and sounds a bit "plasticky", and well, small, compared to the FR-12.
The FR-12 sounds to me like a 3x12. Not quite a 4x12, but bigger than a 2x12
I figured I'd never find myself wishing for a smaller speaker, but I could potentially wish I'd gotten the bigger speaker.
Like engine displacement, bank accounts, penis size . . .
