they dog is darker than most of the other models, but not one dimensional
I've had it in my 1973 gibson les paul custom, and it sounded pretty close to the holy diver, but a bit darker, softer and lower output... more open due to the lower output, of course, but with a similar center midrange density
it didn't sound as open and clear as the riff raff does in the same guitar, but still retained lots of clarity
the riff raff has quite flat mids and lot of top end, while the dog has a tamed top and it is very midrangy
right now I have it paired with a neck cold sweat in a 1978 greco eg900 les paul standard (brazilian rosewood/maple neck)
it sounds pretty good in this particular guitar, stronger, lot middier and more dense sounding than the riff raff in the les paul custom, but not as 3D
the riff has a spankier and punchier attack on lows and highs (probably cause my raff has a custom thicker magnet), but the dog feels gainier
if you enjoy the holy diver but want classic tones, you'll love it
not a true Zeppelin sounding pickup, in my opinion (I'd still pick the mule or riff raff for that), but reminds of 90's bands with vintage vibe tones, like Soundgarden and lots of stoner bands
no experience with the neck dog, diver or raff, though
ps: that tone in the video is amazing :o
