Random question, for those of us in drop-B tuning, what is the height of your guitar strings on the 12th fret?

Depends on your string guages and how picky you are about fret buzz.

Through an amp, you really only hear the fret buzz if notes are being choked short. If they aren't being choked short but you hear a bit of a buzz acoustically, or without the amp, that is welcomed, just means your action is pretty low.
