Humidifier for dobro?

[Per Berner]

Since relative humidity can go below 20 % this time of year where I live, I have humidifiers in all my acoustic guitars. But I haven't found any that will fit a dobro. Does anyone know of a suitable product?

Aloha PER. The 50 years I lived in Alaska I kept my 12’x18’ music room at 50% with a regular humidifier ..during the coldest times it would take 1/2-1 gal/day.. In the summers I used a DAddario dehumidifier.

Per, I concur with Larry. I gave up on individual instrument humidifiers, and bought a whole-house humidifier that keeps everything indoors at 30-40% in the winter. Helps the winter nosebleeds too!

In the world of rural and hillbilly music, we use an Irish humidifier (1/2 a potato) in the string compartment of the case. Inexpensive, effective, replace as needed.

Thank you guys, but not what I'm looking for. It's hanging on my living room wall, not in its case, and I don't want the hassle of a big electric humidifier.

Most all guitar woods are built at about 10% humidity (give or take). Humidity in a house never gets that low and changes at a very slow rate. There may be other reasons to add a humidifier in your house but protecting your guitar wood is NOT one of them.....and adding a humidifier in a guitar case is just doing more harm then good.

No cases here either, just ready to play wall!

Chris, you are right that most guitar woods are at about 10% humidity but that is the actual water content of the wood, NOT the atmospheric conditions during the build.
Most builders will build their guitars at 40 to 45% Relative Humidity which is a measure of how saturated the air is.
At this relative humidity the wood will reach equilibrium at about 10% moisture content, but will still shrink or swell as it loses or gains moisture with changes in the atmosphere.

Best of all is to humidify the whole house. Many furnaces have built in humidifiers. Otherwise, humidify the guitar room. If that is completely impossible (doubtful) humidify the case and keep the instrument cased. Humidifying the body cavity only is a bad idea because the humidity is not evenly distributed. It doesn’t touch the fretboard so you get “fret spout”. It doesn’t reach the outside of the instrument. And there is the risk of water damage if the humidifier leaks into the body.

Or you can move to the Pacific Northwest where the indoor humidity is in the Goldilocks zone year round.

I've been using these in all my guitars for more than 15 years.

The one time I had an issue with a humidifier, I had another overnighted to me without question.

I use Oasis humidifiers and keep one in the case with my Dobro. I have no experience in leaving guitars hanging on the wall for an extended period but logic says a room humidifier would be essential.
