What is the purpose of a guitar signal splitter and how does it work to split the signal from a guitar into multiple outputs?

A guitar signal splitter is used to send the signal from a guitar to multiple destinations, such as amplifiers or recording devices. It works by taking the input signal from the guitar and duplicating it into multiple outputs without degrading the quality of the signal. This allows the guitarist to send their signal to different equipment simultaneously, enabling them to achieve various sound effects or record multiple tracks at once.
