Resonant Guitar
Every part of this dark, shining guitar, from the strings to the soundboard, is constructed of metal. When the strings are strummed, the gilding on the guitar ripples like a liquid. A resonant guitar is a virtuoso handheld musical instrument that grants a +2 item bonus to Performance checks attempted while using it.
A resonant guitar is a planar key for Interplanar Teleport and similar magic to travel to the Plane of Metal. When using it in this way, you can play a tune inspired by your destination to make it more likely to arrive where you intend to be, appearing 1d6×25 miles from your intended destination instead of 1d10×25 miles away.

Traits
Something with the magical trait is imbued with magical energies not tied to a specific tradition of magic. Some items or effects are closely tied to a particular tradition of magic. In these cases, the item has the arcane, divine, occult, or primal trait instead of the magical trait. Any of these traits indicate that the item is magical.
Effects with the metal trait conjure or manipulate metal. Those that manipulate metal have no effect in an area without metal. Creatures with this trait consist primarily of metal or have a connection to magical metal.
An effect with the sonic trait functions only if it makes sound, meaning it has no effect in an area of silence or in a vacuum. This is different from an auditory spell, which is effective only if the target can hear it. A sonic effect might deal sonic damage.
