Recording with your iPhone's built-in microphone is a quick and easy way for musicians to sketch out song ideas. To take the iPhone's audio-recording capabilities to the next level, you'll need to drop some money on a quality recording app, and some kind of adapter for connecting instruments or mixers.
Fortunately, the folks at Sonoma Wire Works have created the best solution we've seen yet. The GuitarJack ($199) plugs into the dock connection of your iPhone or iPod Touch (though the latest iPhone and iPod models aren't supported) and bestows them with a 1/4-inch instrument input, stereo line input, and headphone output.
Unlike some of the guitar-specific or mic-specific accessories we've tested in the past (such asor ), GuitarJack distinguishes itself with a uniquely durable aluminum construction and a Switchcraft instrument jack made from a nickel-plated brass.
