With more than 500 guitar-related iPhone apps in the App Store, it was only a matter of time before someone released a device that attaches an iPhone to a guitar. Castiv's Guitar Sidekick does just that, clipping to your guitar while providing a mount for your iPhone or other mobile device.
The Guitar Sidekick clips onto the strings of your guitar between the nut and the tuning pegs—a strategic location that keeps the Sidekick from affecting the sound of your guitar. Attached to the clip is a rotating clamp that can be used to mount any model of iPhone, iPod Touch, or numerous other mobile devices in either portrait or landscape view.
Clamping your iPhone to your guitar could be useful for a number of reasons. With the iPhone easily viewable, you could view and play along with video lessons, read lyrics off the iPhone's display, play along to a metronome app, or even tune your guitar with a tuning app. Guitarists who use tabs—simplified music notation for guitars—could benefit from the ability to play tabs without being stuck in front of a computer display.
The Guitar Sidekick is compatible with virtually any kind of acoustic or electric guitar and sells for $30.
