Stoner is all about using enough distortion from pedals and amps that what comes out the speakers bears minimal relation to what comes out of the bass. And if you check everyone famous that played a Rick, that is how they are best presented, always driven valve amps.

Agreed, Ricks tend to sound best through valve amps, but there's a big difference between Chris Squire's Marshall and a 50w Matamp on full. Most of the classic examples I can think of (Squire, Geddy Lee, Roger Glover etc.) still retain the unique tone integral to the bass itself. Every time I have heard one used in a Stoner or Stoner-type band the amp has been driven to a comical extreme that sounds pretty awesome in itself when done correctly but tends to render the bass being used as irrelevant.
I just don't think Ricks are suited to extreme drop tuning, from my personal experience. I played in what was generally termed a stoner metal band for many years and my Rick never did the job as well as a Precision bass, for example, which coped ith the downtuning better and still retained the tone I expected.
This is not knocking Ricks in any way - I love them and their sound, and have owned several over the years, but as with every bass they have their strengths and weaknesses, and are better suited to certain things more than others.
But it's all down to personal experience - iiipopes above has had good experiences with downtuning his Ricks. A lot depends on technique and style of music.
