Castiv Guitar Sidekick

The Castiv Guitar Sidekick clamps your smartphone or media player to the strings at your guitar's headstock, allowing you to view videos, tabs and apps at a sensible angle.

Be wary of really heavy devices, though - the weight of the device on one of our guitars was just enough to lift the high E string out of the nut. Still, in all but that instance the Sidekick worked exactly as expected.

3 / 5 stars

A handy little gadget.


Heavy devices can lift out your strings!


Would make a useful addition to anyone with a growing collection of guitar apps.
