Can you plug one guitar into 2 amplifiers at the same time?

Yes, it is possible to plug one guitar into two amplifiers at the same time. This can be done using a splitter cable, also known as a Y-cable, which has two female ends and one male connector. The male end connects to the guitar's output jack, while the two female ends connect to the input jacks of the two amplifiers. Using a splitter cable allows the same signal from the guitar to be sent to both amplifiers simultaneously, enabling the player to create fuller, richer sound or achieve other desired effects.
