Figured I'd chime in. In 2022, I bought a brand new Ray34 in poplar burl. When I initially got it, everything was fine, but eventually developed the same issues with the tuners. Only reason I'm posting this is because I've pretty much put that bass away for the past couple of years since I couldn't tune it. Well, for some strange reason, I was like, 'I'm going to see if I can replace the tuners' so went googling to find what would fit the existing screw holes and found this thread. I figured, what the heck, and emailed Sterling yesterday to see if they would possibly replace them since it was a known issue (or at least hoping, before I go through buying some). They responded today asking which tuners were affected and told them all 4 and sent them some pics. I know I'm way past warranty on this bass, but hoping they will do the right thing and replace them for me.
Here's some pics of the bass along side a sub 5HH I got super cheap (and absolutely love.. sounds amazing). I replaced the original clear pickguard with a 3 ply B/W/B.
