After playing this pedal two different times about a month apart, I decided to pull the trigger. The BD-2 side is really really good and I have never been a fan of the BD-2 - this incarnation seems a bit smoother to me. The Angry Charlie side is just a great sound and I have always been a fan of the Guv'nor that inspired it. What is really good is that the two sides are voiced similarly so going from the BD-2 to the Angry Charlie just seems like a natural progression. Also, with the 3 different ways to stack them together, in series with either before the other and in parallel, there is just so much tonal variety on tap. Hats off to Boss and JHS for concocting such a great combination.
