I've mostly stayed away from guitar and guitar like libraries, mostly because it seems silly, and at least in part because it feels like cheating. I should play these parts it dang it!
Well, this mandolin sounds tons better than either of my mandolins, so I'm going to make the leap. I no longer own a nylon string guitar, so I think I'm going to grab that at the same time. I do have Renegade (I don't have anything that sounds remotely like that, and I needed it for a score) and I do like his approach to controls.
I've owned Brio pretty much since it was released, and still use it for miscellaneous percussion in the majority of my projects.
This could get expensive! He has some really nice libraries.
