The issue with moving the boost around is that it is, more or less by definition, the very end stage of the original Phamacist design (or rather, a choice between two differently-biased end stages).
The more that I fiddle with this circuit, the more it feels to me that Vox got it right in the amps the first time round. Also, I'm pretty sure Aclam's "bias" on the Mocker/Beatle Juice is born of a schematic mistake – their base resistors on Q2 might work well to help control the fuzz in fuzz mode, but don't work so well when trying to run it as a clean channel. I'd even go so far as to say that the Sergeant Fuzz might be a better platform than the BJ for this project, at least up until the redundant mids control (and ditching the asymmetrical clipping diodes)...
