Karl, you keep pushing the 50% moisture thing. You getting a rebate on water?

In
this thread, Arnold responded to your advice by pointing out what I always considered to be the case-- that 50% is too high to recommend across the board. The conventional wisdom is that too low a level of humidity (e.g., 35%) is dangerous all by itself. A high level (e.g., 50%+) is not dangerous so long as its maintained without rapid and large swings. A safe overall level is in the 40s because its a good absolute level and is where most environments sit. Thus, as you take the bass from one place to another, you're not likely to expose it to large changes.
