If you have to do a lot of toe tapping to switch between guitars, effects, or amplifiers, the LS-2 can make your onstage life a whole lot easier. The Line Selector is a extremely useful box that serves up various a/b, loop, and mixer duties. As an A/B box the Boss reigns supreme with individual volume controls and effortless switching. As a loop selector the LS-2 offers a few various modes that can clean up your tone by eliminate noisy effects from your chain until its time to use them. 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 these swift easy changes with the tap of a single pedal. As a Splitter, this allows you to toggle between three amplifiers. This is one of the best devices of its kind on the market, although we hope Boss expands upon this idea with their new dual pedals.
