It will sound exactly the same, but you will not have the same feeling. That is true.
Currently, nylon guitar is modeled quite accurately. I have been using V-Guitar intensively, since the VG-8. The feeling is not the same, but when you've been playing it for a while you got immersed like if you were playing a nylon.
Of course, some purist will never play it because they want to feel the real thing (like the ones that would neve change a tube amp for a modeler) But, can you imagine replacing your current pickup for any Bare Knuckle, Suhr, Lollar, etc. with the simple switch of a preset scene? Virtually changing the position and angle of the pickup? The VG-99 can currently do that, but with a very limited number of generic pickups (classic single-coil Strat, modern single-coil Strat, Humbucker, P90, Lipstick and Rickenbacker Humbucker). Someone has to raise the bar on that area.
We've had enough Cab Packs, now we want Pickup Packs and Guitar Packs!!
