Not out yet, I am going to use my jam points and pre-order it. I have Amplitube 3 and it sounds great.
Jam points???
I put the app on my new iPhone, but haven't played with it yet. No interface.
You can play their demo sound clips through the effects and amps to get an idea of the sound.
Jam points are on the ik website. as you buy their stuff you get bonus bucks you can spend at their store for up to %50 off.
