RG is a strange friend: it does, what it says, but it does it differently. This could be the reason, why a lot of guitarists laugh about it's 'artificial' sound and a lot of non-guitarists, who want to have a virtual guitarist, complain about it's not 100% guitar-emu boo.

A great plug-in and a lot of fun!
