If you've ever tried to connect your guitar or microphone to your computer, you'll appreciate the simplicity of Griffin's GarageBand Cables. Each electrostatically shielded cable is a generous 10 feet (3 m) long, with a stereo mini-jack at one end, and eliminates the need for additional adapters -- just plug one end into your Mac's input port (or your iMic) and the other end to your axe.
