Semi-hollow guitars are a type of electric guitar that feature a solid center block surrounded by a hollow body. This design allows for a unique blend of acoustic and electric qualities, producing a warm, resonant tone. They often have f-holes, similar to those found on acoustic instruments, which enhance their sound projection. These guitars are popular in various music genres, including jazz, blues, and rock. Notable models, such as the Gibson ES-335, are known for their versatility and ability to handle both clean and distorted sounds effectively. Musicians appreciate their balance of sustain and feedback control.
