I live in a very humid place. (Cigars keep in my humidor very well, thank you, without ever adding water to the little humidifying thingy). 90%+ is common, and only rarely do we see humidity below 60%. When things get really bad in the house, we run de-humidifiers, but they make a lot of heat and noise, and are costly to run. Generally we just live with 70-80%. Several times I have passed on buying a bass I was otherwise very attracted to, because of age and/or extensive repair history, on the theory that high humidity is more likely to cause havoc with such an instrument. In particular, I have worried about buying such a bass in a dryer climate and relocating it to my soggier environs. However, more recently I have begun to believe that I may be mistaken in this concern. Based on reading and perhaps a little instinct, I am begining to think the real risk comes from sharp drops in humidity, leading to a bass drying out too fast, and not from high humidity per se. Wonder if anyone has experience or insights which can help me here. Particularly interested just now, as I will be travelling in the near future, and the temptation to look at and possibly acquire another bass is always there. Just can't forget a lovely no-name 100+ yr old five-string I once passed up a year ago over these concerns. Reasonably priced, big but very playable, strong, clear, rich tone across all strings, ppp to fff, and very quick response, but riddled with repairs. The work appeared well-done, but it worried me for this climate.
