iPhone Guitar Speaker is coming to a rock concert near you

It was inevitable that the wealth of iPhone music apps would eventually give rise to a new category of complimentary accessories, but The Fingerist could possibly be the coolest.

Developed by Japan-based Trinity, and selling for just $150, the device allows you to simply slide your iPhone or iPod Touch into its base, start up any iPhone app like Pocket Guitar, and begin rocking out via the speaker housed in a faux wood grain body supported by a guitar strap. The unit also offers the option of plugging into a real amp, essentially ensuring that we'll see this on a real rock show stage soon. You can see video of an impromptu Fingerist Japanese jam session here.
