A "24-fret" guitar refers to a stringed instrument that has 24 frets on its neck. Frets are the metal strips that divide the neck into sections, allowing musicians to play different notes by pressing the strings down behind them. Having 24 frets provides players with a wider range of notes, enabling them to play higher pitches and more complex melodies. Many electric guitars, such as those made by Gibson or Ibanez, often feature 24 frets. This design is popular among rock and metal guitarists who require access to higher notes for solos and intricate playing. The additional frets can enhance a guitarist's versatility and creativity in their music.
