The icon is a guitar. The guitar is an instrument that has a whole in the center. Strings front the top of the guitar to right above the center. On the top of the guitar it has tuners which are used to tune the strings on the guitar so they are close to perfect pitch.
This is a Guitar icon. We've made it in iOS style
, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 13,700 icons, all in the same style and quality.
