Still today no one yet seems to be able to add that live,rich tone,"especially" on hi gain amps.
I heard ,and tested S-Gear and Recabinet 4.They are getting closer,but still when you listen raw tracks of real amps,they seemed to me very high end opened,with more harmonic content.
And that is even more noticeable when you hit simple riff and listening.I do not know is it flaw in the cab,preamp or power amps section of emulation,I`m far from tech guy.But something is missing.
Whatever it is,I strongly recommend you to try to emulate that missing link that makes every amps sims muffled in compare to real deal.
