My Mississippi Queen is also a neck pickup. The bridge should be even punchier due to a slighty hotter wind and AV magnet.
The Black Dog is great, on the right woods. I think it needs darker guitars. I rate it as the second brightest vintage-hot humbucker (brightest being the Emerald).
It has lots of low-mids but also highs, with smoother upper-mids and very tight bass. Sounds very good with clean and crunch buy really shines with high-gain and tuned down.
Still, the Mississippi Queen on the neck position had more output than it. Now I have the Mississippi Queen with an Abraxas and they balance better in output and tone.
