What high quality guitar software is available to buy? I know of Amplitube, GTR, and Native Instruments GuitarRig. Are there any others. I was not impressed with GuitarRig2. I do not know about 3. GTR is amazing, but it is not working for me as a plug-in in Cubase (does anyone know why). Amplitube is ok, and realistic, but it seems more limiting to me.

Anything I'm missing? Thanks.

Ibanez RG321MH (Air Classic/Tone Zone)
