I don't understand

@@ShaunDobbie it's a guitar thing I think it was Lynyrd Skynyrd I don't remember the song but its iconic and a lot of other band members use it also the plastic to black thing would go into their mouths and as they would sing it would echo through the two and go down to a pick up like a microphone and as you would talk it with song like your guitar kind of like you were talking into a fan the academy young you might be unfamiliar 😆😂 that's understandable they sell them play real music nowadays that was on the verge of making everything acoustic into an electronic device pianos made into keyboards keyboards made into synthesizers guitars made into keyboards then there was the hybrid guitar and keyboard I think it was called a keytar history with instruments and electronics is seemingly never-ending 🤓😎
