The LS-2 Line Selector by Boss provides you with a very easy way to switch between two signals. For instance, you can switch between two effects, amplifiers, guitars, or other audio sources. You select from two lines and six loop modes. These modes indicate how you switch between the two lines, such as A to B, A+B to none, etc. The LS-2 can also provide power to multiple Boss pedals thanks to the additional 9 Volt output.
