If you have to do a lot of toe-tapping to switch between guitars, effects, or amplifiers, the LS-2 can certainly make your on stage life a whole lot easier. The Line Selector is a extremely useful box that serves up various A/B, loop, switcher and mixer duties. As an A/B (or even C) box,  the Boss reigns supreme with individual volume controls and effortless switching. As a loop selector, the LS-2 offers a few modes that can completely clean up your tone by eliminate noisy vintage effects from your chain until its time to actually put them into action. These modes are also a lifesaver if you are having problems executing multiple pedal combinations between verses, choruses or bridges in your songs. By throwing all these pedal combinations into various loops you can make swift easy changes with the tap of a single pedal. As a splitter, this allows you to toggle between three different amplifiers. This is one of the best devices of its kind on the market – although we really hope Boss expands upon this concept with a few more options housed in their new dual pedal series.
