A clone of the Zvex Mastotron, coming in at less than 50 quid, this is what bass player's fuzz dreams are made of.
I've only just discovered Red Rocket Music. Don't know anything about them but I'm guessing they're a small business, UK based, and they make a bunch of copies, clones, tribute pedals - whatever you want to call them.
I have two from their collection, and they both sit beautifully in the mix.
