The BOSS LS-2 Line Selector pedal lets you switch easily between several different effects and route input and out signals flexibly. The LS-2 can also supply 9V DC power to several BOSS small pedals when used with an AC adapter - this makes the LS-2 an ideal power supply and master switching unit for multiple effects setups. Just as you"d expect from BOSS, you get the rugged construction and dependability that makes the LS-2 a road-ready essential for your gig bag!
