How much "relative humidity" can typical audio gear (amplifiers,

I have a room that has a 50% "relative humidity" that I intend to use
for recording and practicing with my band. I have no idea if this
humidity is "normal" or not, but to me it looks like a pretty high
figure. What made me even think about it is that there happens to be a
hygrometer on the wall; it actually doesn't seem particularly humid in
there.


Most people say 50% is ideal, but I find the drums sound better and
hold their tune better, and to some extent guitars do too, at around
60-65%. You definitely don't want to go below about 30% if you have
any wooden instruments around, and you don't want to go above about 80%
if you can help it. Here in MN, the central air takes care of the
humidity in the summer, but it gets very dry in the winter. A
humidifier is essential.
