A bit more info bump... I was chatting to Douglas Castro of Darkglass about placement when I was using this with my B3K... he said...
[i]"I like to place it after the B3K because it allows me to change the equalization of it, so you can make it either warmed, or more percussive, and also use it as a volume boost for solos... so yes, after it is my number one choice![/i]"
Same would go for any dirt pedal I suppose, although I do move my EQ pedals around in the chain to see how they affect different pedals. Was wonderful [i]in front[/i] of my DHA VT1.
