D'Addario Guitar Humidifier Pro - Acoustic Guitar Soundhole Humidifier with Sponge - Non Drip - Suspends from Strings - Holds 12x Weight in Water

Just what I was looking for.

Left my luthier built maple acoustic hanging on wall whilst away for 2 weeks, and came back to action way down. It has been unseasonably warm and very very dry in eastern England this year. Never had this problem before, but before I panicked, I got one of these, and after 4 days in its case with the humidifier, the action returned to normal. Easy to use and did the job without expensive set up/ neck adjustment.

I was getting fret buzz on my Taylor acoustic and this humidifier sorted it in about 5 days. Easy to use and did the job.

Very easy to use and does the job

I would never know if it’s worked or not, I’ve never had a problem with a guitar in25 years but press pressure I have given it a try but how would I know nothing has changed with guitar

Cumple su cometido

Holds a lot of water, works well to keep the humidity level in my guitar case at good levels. Everything works exactly as I would expect.

I am sure my Lakewood smiled and said thankyou dady oh..

中身はスポンジみたいなものが入った単純な構造。このスポンジを湿らせてケースに入れて弦の間にぶら下げます。効果を確認のためギターの中に湿度計も入れ、中の湿度とギタートップの膨らみの変化を確認しましたが、確かにこうかはあるようです。
