I suspect you're right, jedzep, as it isn't all of them, just the upper 4 (so far, at least, but I figured the tension of the low E string would be strongest so I'm surprised that one didn't pull forward as well). If they fill and re-drill, do you think that will impact the tone? Like I said, I'd played a number of new J-45s over the years and this one has the best tone I'd heard, hence being extra bummed about this issue. Also, the model is out of stock (says the Gibson website) so if they did decide to replace I'm guessing I wouldn't be getting the same model (really like the chunky neck).
