No, I don't think so. The paperwork said a couple of days. I just waited a little longer. I think the whole bass sort of settled in a bit. Felt sort of akin to a speaker breaking in, got better sounding after a bit.Is a week the official norm for allowing a bass guitar to acclimate if its been shipped across the continent? This concerns me because after all, we only have 10 days to send the instrument back. I wouldnt want to send a perfectly good bass back prematurely nor would I want to be stuck with a problem neck either.
