So I'm going to jump on this a few weeks late. I was lucky enough to score a BDPG from OP - a red one with no picture that he picked up just before the pink one came his way. I only just got to give this a good run last night.
I used the pedal to get a phat reggae/dub style sound that breaks up when you dig in; it works a treat.
I've had to go a different way to make this work. At first, I naturally put the BDPG at the end of the chain, however I'm also trying out a compressor (MXR Bass Comp) for the first time and found that the compressor impedes my ability to push the pedal into overdrive.
Part of the compressor's job is to keep an envelope filter from peaking too much so the compressor has to be after that. I have a W&C PPB which gets the top end shaved off by the comp, but has no issues after the comp (would that be because the PPB is buffered?). The BDPG has no issues before the comp, but like I said, won't break up after the comp.
So chain is Bass > BDPG > Filter > Comp > W&C PPB > Amp. And it worked great for me.
Now I gotta find a position for a B3K\B7K...
