Total Darkglass convert here. I heard the B3k a couple of years ago and I loved it, but I couldn't justify spending that much on a dirt pedal.
Fast fwd to last fall, and my svt crapped out. I never really liked it and I started looking around for something I liked more (and that could freaking carry myself).
I ended up getting the DG microtubes head, which has the B3k and vmt built in. I love it very much. It's super flexible and has a footswitch for clean/dirty. Perfect for flipping between swooshy and grind lol.
This is our new EP. I used a Mexican jazz straight into the microtubes - all the dirt you hear is the head on the b3k setting.
Plus I can carry my own amp now. My head went from 85 pounds to 6
