I've never waited that long under the same conditions but that's probably foolish of me and I've just been lucky. Not sure if this is related or not but when I received my 514ce LTD last year after letting it warm up for as long as I thought was necessary (probably not long enough) I took it out of it's case, tuned it up and started playing. That first night I was positive it was going back. It was just dead and lifeless with no sustain and sounded like an all laminate guitar. The next night it sounded completely different and by the end of the week it became a guitar I will never part with. The granadillo / cedar combination is truly magical. No, it was not my imagination and me just getting used to the sound. I already had a 414ce R for comparison and it was that guitar that made me want another Taylor. The only explanation I can think of for this experience is the guitar spent two whole days in a truck in below zero conditions and I hadn't let it acclimate to it's surroundings long enough before opening the case and playing it. I'm lucky I didn't damage it and fortunate I kept it for a week to let it acclimate to it's new home because man, this guitar is hard to describe! I know another guy on another forum who feels the same way about his.
