Why am I impressed with this now universal AU/VST?
For your money on the surface you seem to be buying a basic thrash metal guitar simulator. So wherever you have midi notes sitting, you could replace with some reasonable heavy guitar sounds.
The reviews do admit it is not the best for getting reasonable acoustic sounding guitar - fair enough.
But not only do you get the ability to change midi notes, you also get to use 16 different foot pedals and amp cabinets to change the sound of your AUDIO TRACKS along with presence, drive, bas, mid, treb and gain over the sound as well.
When you look at it that way, it may be a very good buy and well worth a look at the demo 4MB installer.
And no I don't work for the company.
