I have been wondering why we need humidifiers for our instruments when years ago we never did.  In the 60's I had never seen a guitar humidifier.  Did they not exist, were guitars better made?
I found an answer in the current "Guitar Aficionado" Vol. 5, no. 1, page 72 in an article by Flip Scipio.
I have copied this short portion from his excellent article:
"Guitar makers used to buy a big log of spruce, split it, stack it, and air dry it until they felt it was aged enough to use.  In fact, a number of individual guitar makers still do this, but most guitar manufacturers have had to resort to speeding up the drying process to keep up with the demand for their product.  This sped-up version is generally referred to as kiln drying; it means sticking the wood into an oven.  As the demnd has grown and the wood supplies dwindle at an increasing rate, the aging process is manipulated, with the direct result that newer guitars seem more sensitive to sudden humidity changes thn old ones."
I found this interesting.  Hope you do too.

Thanks for posting. I've read that for the first five years its recommended to keep the relative humidity constant. Martin care and feeding guide I think. Some tops are gonna crack regardless of humidity, like some will be fine. With great reward also comes great drawbacks. Impossible to predict what an acoustic guitar will do. Like women.

I started playing in the Souythwest during a long drought (the '60's). Commonly RH was 10%. WE never heard of humidifying guitars. But most of us played nylon strung with much lower string tension. I did have the neck on my Goya reset a few years ago after the glue failed.

Go take a look at Elderly's vintage section.  All the descriptions read "Excellent, except for repaired crack".
