what are the guitar string knobs called
Answers. 1  The thinnest string is called the high E string in standard tuning. Tuning makes your guitar sound lower or higher using the knobs at the headstock of the guitar. Standard tuning is just (from the thinnest string to the thickest string) E,B,G,D,A,E. There are different tunings but guitarists call this standard tuning to have a consistent tuning between guitarists.
