A semi-hollow body is a type of electric guitar design that features a solid center block surrounded by a hollow body. This construction allows for a balance between the warm, resonant tones of a hollow body and the sustain and feedback resistance of a solid body. Semi-hollow body guitars are popular in various music genres, including jazz, blues, and rock. The design typically includes two f-holes on the top, which enhance the instrument's acoustic properties. Notable models, such as the Gibson ES-335, exemplify this style, offering players a versatile sound that can adapt to different playing techniques and styles.
