Hallo, Mighty Konrad. I like the new avatar.
I upgraded to Guitar Rig 5 and think t is a whole different beast. I also have Amplitube 3 and TH2, but still use Guitar Rig 5 a lot. There are several major improvements over 4, not least the Control Room, which handles all the cab and mic business, plus several new amps and effects.
I recommend it. A lot.
How are you getting on with EZdrummer, by the way? Have you given in and bought loads of the expansions? I warned you that they are addictive..
Hope all is well with you.
Jonathan
