Ah!Any idea what the rattle is? Truss rod vibrating? Or is it more like a high fret? My stingray was plek’d, still needed a shim, took forever for the neck to settle, and had lots of electronic issues under warranty that took a long time to fix. I guess if you’re willing to keep chasing down problems you’ll maybe end up with a great bass! I love mine now, but it was a dog when I got it.
I think it could be something about the frets, even tho it’s more noticeable on E-A-D strings. E and D are impossible to play in that area, they rattle real badly.
Everything else is tied up properly.
Swamp ash body, as opposed to the poplar of the 5H (but that’s just an extra info, it doesn’t matter)
