ABY

An ABY switch is a handy device used by guitarists and bassists to switch or combine two different signal sources or outputs. It lets you toggle between two amps, two effects chains, or blend both signals together, offering versatile routing options. For example, you can send your guitar signal to Amp A, Amp B, or both at the same time. ABY switches are great for live setups where you want quick changes or to create layered sounds without unplugging cables. They come in passive or active versions, depending on your gear’s needs.
