New Gadget 2011

Learning the guitar is something best done in private. Tascam's MP-GTI MP3 player ($269, tascam.com) provides a practice space inside your headphones. Expressly designed with apprentice guitar gods in mind, it has a built-in metronome and tuner; plus it lets you loop sections, adjust tempo and shift pitch. Plug in your ax and it'll even supply overdrive and other effects.
