Anywere that here is high humidity there are also periods of low humidity. Tony With all due respect, that statement is wrong. In Hawaii, and I presume in other tropical areas, like Singapore, the humidity NEVER drops below 70%. Surpisingly, the humidity rarely goes over 90%, either. But it is always in that range.

Anywere that here is high humidity there are also periods of low humidity. Both rods have een installed in "hopefully closed areas" and when the humidity drops down to ay 40% you can assume that these rods are going to reduce the effective umidity level down to about 25% causing the action to become loose and the oundboard to dry out to lower than it should be. Even fitting a humidistat to ear the soundboard will not stop the action from cooking. One way only to do it roperly, full climate control system with under cover under the soundboard, eep thr lid closed and close the key fall when not in use.

The heater on the oundboard according to the tech that installed it helps to prevent rust. The ther rod in the action cavity is the standard installation in our hot and humid limate. Its on 24/7.
