From a practical standpoint the difference between a good bass and a great bass isn't necessarily the pedigree or origin of manufacturer, rather its based on the abilities of the person sorting it out.
I'm glad that you found something that speaks to you and has your voice. That's something that can be difficult to find.

Well, it's taken me a
very long time to realize the universal truth in what you're saying there, Diogenes

, but there's no getting away from it - this bass just feels, plays and sounds 'right'! Maybe it's partly due to my starting off with low expectations

, but it doesn't really matter now. I've finally got a StingRay which ticks all of the boxes (even if it doesn't have the wonderful vintage tone of the '77 'Ray that it replaces

).
I like this bass and don't think it needs to be upgraded unless you wanna experiment with new pups. Tuners are good. don't know why you say they are poor quality
Although this bass is really heavy, but there isn't much you can do about that.
I think that I implied that the tuners were not good quality in an earlier post

, but I should clarify that a bit. The tuners are a different shape to the 'standard' MM ones, which immediately identifies the instrument as a 'copy'. They are also bright chrome instead of the more subtle nickel plating on the MM ones. Apart from that, they are perfectly serviceable units and any roughness to the finish is purely cosmetic.
I only changed mine because I already had an original MM set sitting collecting dust and wanted to make my Sterling look a little more authentic (the MM ones are also a little heavier and feel a bit stronger, but that may just be a pyscholigical side-effect of the weight

).
To be clear - there's really nothing 'wrong' with any aspect of these Sterling Ray34s, IMO - even the strings feel like proper Ernie Ball Slinkys

.
As for the weight - mine is 9.8lbs in total. That actually makes it the
lightest StingRay I've ever owned. My '77 was 9.9lbs, my 2004 EBMM was 10.5lbs and my '88 fretless was well over 10.5lbs

. I think that the bottom-heavy shape of the body, the brass inserts for the (chunky) bridge mount, the huge pickup magnets (not to mention the slab body on the pre-EBs and modern 'Classics') all add to the reasons why StingRays are traditionally heavier than Ps or Js.
Still, as ash bodied basses go, a nice two-piece swamp ash body like this is normally the kind of thing that you find on higher priced instruments.
In case you hadn't guessed ... I like this bass

!
(P.S. The Ernie Ball neck plate that you see here is another left-over from a 'project bass' that I took apart and sold. It adds nothing of any value whatsoever to the Sterling bass, so I guess that I'm just being a bass snob by putting it on

. Guilty as charged

!)
