RE: [Harp-L] Mould on amplifiers

Aaahhh, one of my favourite topics since I attended introductory
lectures in climatology... See also: http://en.wikipedia.org/wiki/Humidity.
Certain places in Australia are mentioned there as well.

I would consider 50-55% percent (relative air humidity) to be o.k.
for a healthy indoor climate. For stringed instruments humidity
should be above 45%. I also think that the pearwood combs of many
harmonicas might as well get affected by too low or too high humidity
(if they are stored over a long time in that climate).
Didn't Hering once have issues with brandnew harmonicas (even with
plastic comb) smelling mouldy due to inproper storage?

I would invest in a real good hygrometer. I found out that the cheap
ones are very imprecise (I once bought cheap ones for each room
and they all differ for about 5-10%).

"(Im not sure what % of humidity is acceptable....... anyone) "

Hey Dane, the dehumidifier I bought defaulted to 35% but I raised it to 
55% for reasons of economy and haven't had a problem in the room I use 
it in (mold had been forming on the baseboards, etc). Not sure if that's 
OK for electronics, amps etc but it's working for me. Let's see what 
others say.
