I was sold on the B3K from that first video where the pedal's look hadn't been pinned down yet. At the time I was playing a five string Jazz style bass through a Mesa Walkabout and that was exactly the gear used in the demo so I took a chance and ordered what I believe was the first B3K to be sent to the U.S.
It was serial number 7. And I was nervous to plunk down that much coin for a brand new pedal from a brand new company in Finland. But the build quality was stellar and the sound was EXACTLY as in the demo vid.
I've bought a number of dirt pedals based on video demos and sound clips and have been burnt in the past when they showed up and sounded drastically different through my gear.
So for anyone who sees a B3K demo and likes that super crunchy and still really clear, cutting sound I say grab a B3K.
