I bought the LS-2 in order to quickly change from rhythm to lead, which previously would have been two och three stomps, but is now only one.
Since then I have experimented and tried out a lot of other ways to you it. One cool way is to dead patch one loop and increase the volume on that same loop. Voila, you've got a fairly good clean boost!
Only thing I miss is the ability to hold down the pedal and with that go back to bypass. Now I have to toggle my way through the lead-loop to come from Rhythm to bypass.
All in all, it is doing all it says and more!
