Amazing

Thumbjam is easily my favorite app on my iPhone. Its complex, detailed, and has a ton of depth to it. It might not be for those who only play air guitar but if you know basic music terminology you should have no problem with the app.
The recordings are clear and everything on it was done very well. Recording music using the instruments is hard though since creating chords on the instruments takes some work due to the small touch screen on my phone so I can see why most recommend it for the iPad instead. But other than that I love it :D
