I have Amplitube 3. I had it on my iPhone , it's not very good in my opinion. Volume is very poor IMO. Now I have it on my Macbook Pro also. It is awesome. Endless amount of amps and effects. Volume is loud. You can also buy more from the Custom Shop to add more into your arsenal. Vintage Amps galore. For the MacBook Pro, I think its around 250.00.Well worth the money. Ikmultimedia.com You will also need a Guitar Interface. Guitar center has a multitude of Interfaces.The Orange Amps are awesome. Slashes Amps are so so. Fender has great Amp selection. You can do a lot with it. You can listen to your iTunes songs and play along with them.
