Hopefully a lot of that smell comes from the case. I'd love to hear opinions on what can be done about that. I had a similar issue with a gorgeous Spanish Flamenco guitar in pristine condition except it smelled like perfume. Not heavily, but distinct. Putting it in front of an electric fan for a few days helped a lot, the steady wash of wind took away most of the fragrance (aim at soundhole, fanning it outdoors is ideal). I still get an occasional whiff of perfume from it, as if the guitar is haunted, but the fan method really helped. For what it is worth, I emailed the manufacturer (Manual Rodriguez) and they suggested putting the guitar in the same room as a dehumidifier for a week; that is dependent entirely, of course, on whether or not you keep your guitar herd in a humidity-controlled environment. They also suggest a few days of a humidifier followed by a few days of a dehumidifier, the thinking there being that the humidifier "opens the pores" and the dehumidifier then cleanses them.
My local luthier, by contrast, who didn't quite buy that theory, simply shrugged and suggested "Well, look at it this way. It adds character".
