Plug your guitar into your iPhone and rock out! That says it all. The AmpliTube iRig is awesome! Download the app from the appstore and control the types of sounds your guitar makes. Whenever I get to the point of playing an electric guitar, this will be mine. The iRig is $39.99 and the app is $14.99. I believe it works on the iPad as well, or will in the future. Check it out!
