Just as the death of arcades hasn’t stopped Ion Audio from putting out cool, new iCade accessories, they aren’t letting the decline of games like Guitar Hero keep them from getting into the plastic instrument race. However, like their previous Piano Apprentice iPhone accessory, the upcoming Guitar Apprentice isn’t a game. Instead, it’s a musical teaching tool.

The device is a full-sized guitar shell that the iPad docks into. The onscreen frets light up to show players where they need to place their fingers and whether or not they are strumming the right chords. From there, players can learn and record songs with compatible apps like GarageBand and Ion Audio’s own upcoming Guitar Apprentice app.

The Guitar Apprentice accessory will soon hit retail for $99 in America before arriving in the rest of the world. If this works, imagine what other instruments Ion Audio could plug an iPad into. The second image shows that a drum accessory is in the works. What else could be coming? Saxophone Apprentice anyone?
