I just got an iPhone 4 and one of the apps you can buy is a Gallien Krueger amp with the ability to play along with the songs on your iphone. The sound is awesome and the eq section is very accurate to the real thing. You can play through a 4x10 or a 1x15 virtual cab. This thing is perfect for anybody who wants to play but doesn't want to haul a huge rig around, and is great for learning songs. Happy playing everyone.
