So much more than a "line splitter", the LS-2 offers two effects loops along with every combination of how you want those inputs routed. This same pedal can be used to split a signal chain, add in (and take out) an effects loop, and even blend those loops in every way imaginable. It even offers a "9V power out" so you can use it to daisy-chain power to other pedals. This pedal is ridiculously flexible. I like playing around with my pedal board, and I like having options, so for me the LS-2 is indispensable. Indeed, I will be purchasing at least one more. This is a must-have pedal for me.
