No noise issues with my B7KU (or my B3K and VMT, neither), even when daisy chaining. It is for sure one of the most versatile pieces of gear you will find, and certainly one of the best sounding pedals out there. No doubt about it. It worths every cent.
I have some complaints tho. Why the Hell you, guys at Darkglass, don't include a chorus and a flanger and a compressor and a three channel distortion, that you can change between with your mind while you play. And make it cheaper. And the enclosure is huge, so make it small, so I can fit it in my pocket. And water resistant too, in case I want to swim while playing. And can you please stop using black on it? It makes my heart sad and I don't wanna be sad while I express myself with music. And the knobs... can you make them in red? That way the pedal would match with my favorite shirt. I have other suggestions, but i can live with that. Jeez, I can't understand why you just don't make things the way I like'em.
B7KU = one of the best pedal ever. In fact, to me, it is the best pedal ever. Obviously, YMMV, but that doesn't change the fact that it is a truly wonderful piece of engineering and design, and if you don't like it it's fine, but it doesn't mean nothing more than just that - a matter of taste. Don't get angry on the thing itself or his creator. Pass it up, get what you want. Or better, tweek it until you find some settings you like.
