Ahh, cool! I often wonder where a pedal has been before, whenever I buy a second hand one...
I'm surprised there aren't more BGPs over here! I've owned loads of other green muff clones (BYOC, W&C, EQD, Fuzzrocious), and none sound anywhere near as good! It's tight and focussed, whereas the others seemed far too OTT for the sake of it.
