This pedal have worked wonders for me when I wanted to split my signal into a clean/distorted signal path.
Very well build and can take a beating, works perfectly without power, if you don't care about going without a led light (BEWARE! the led is as bright as a thousand suns, avoid plugging power into it if on a dark stage!).
The only real "missing feature" of this pedal is perhaps a ground lift, but shouldn't be an issue if you have it on some of your other pedals.
