Thanks for your response. As someone who's played bass for over 50 years it's actually not as common as one might think. And I've rarely had to do it to a brand new bass. Especially one that has a list price of $1000. Of course, I got it for less than that but still it's brand new. I have however had to do it on some of the older import bases from Japan and Korea. I actually did mess around with it some more today and was able to get it significantly better by adding a full pocket Shim in the neck pocket. But it was a very thick Shim and it is very noticeable. If you look at the neck pocket / body joint you can see a visible gap. It does play nicely with the shim Shim installed but I still say it shouldn't be needed especially not when it's thick as I had to put in there. That just affirms my feeling that for some reason the neck pocket got routed too deep on this particular instrument. That's why I was asking here if anybody else who owns one has run into the same issue.It may just need a shim. Very common for bolt on basses
I've got some of the actual wooden tapered full pocket shims here and I will try messing around with those tomorrow. if not I'll just probably try another one and return this one.
