didn't try the vhII with ebony board les pauls, but I doubt that the board alone would make it thin soundiing
only had them in a rosewood board japanese lp copy and in a gibson lp standardwith regular rosewood board
they sounded pretty thick in both of them
you'll probably get more attack, but not less body
the riff raff in my 1973 les paul custom has a thicker magnet than usual, which was Tim recommendation, and he said that would deliver a bit more output and bass than a regular riff raff, so it's a lot like a vhII but with a little more mids, and this pup doesn't sound thin at all in this guitar
the guitar has a very snappy attack indeed (probably due to its ultra thin mahogany neck as well), but also a deep low mid heavy sound
the vhII has a thick and bassy sound, but doesn't have much mids, so sits somewhere between the riff raff and a cold sweat voicings (the cold sweat sounded amazing in the same les paul custom the riff raff is at)
it's also one of the most punchy, dry and articulate sounding bkp models, rather than a fat smooth PAF
