All single pick up Stingrays have raised A and D pole pieces - the bass in the pic is a 93 so doesn't have radiused poles - the later basses and Classic have radiused edges. I presume the design was to follow the radius of the fingerboard - note the A and D saddles in this pic also follow this.

Not sure whether setting the saddles with a different alignment would affect this. The other set up element which might affect string resonance is failing to have all of the saddle adjustment screws making contact with the base of the bridge - easily done and not that easy to see.
@DiablousInMusic - Youre correct in your presumption that I do believe that this issue is mostly caused by EQ settings, room sound or the intensity/volume/note choice of other musicians. One of my first bass playing experiences in a band situation back in the early 70s on a japanese Jazz copy through a valve amp playing Halleluyah I Love Her So (Humble Pie version) and I literally couldn't hear myself through most of the song - unison guitar playing the riff (very loudly) and a drummer trying to emulate John Bonham. I still get annoyed when this sort of thing happens but having seen DVDs/heard recordings know the bass actually travels to and through the audience - the guitar may be excruciating where I'm standing but it doesn't travel that far like that. All resolved by all instruments through the PA though.
This photo cracks me up. No weak G, but I have the treble side of my pickup significantly closer to the strings than the bass side. I just like the way that feels under your fingers.
FWIW- StingRays are great basses and deserve every bit of your blind love for them.
As for me, in all these years, no one has ever shown me an actual picture of the subatomic quark. I therefore conclude that they don't exist. (Of course, the lesson here is that an atoms nucleus and electrons were proven to exist MANY years before anyone could present an actual photograph of an atom. It is not reasonable to say something doesn't exist because you don't believe the observations and conclusions of others.)
