Perfect to combine with the Diodarrio humidifier packs. Those packs maintain the right humidity and these will actually rehumidify those packets. I live in Denver which is a high desert, so it gets really dry here. Combining those two has allowed me to easily maintain my acoustic guitar.
Works great. 💯

Have a backup, all wood guitar. I had put in case, and had not touched in months. Pulled it out, and 1st and 2nd sting were fretting out at 11th fret on up. Filled up product, and put in guitar, and guitar back in case. After 4 days, no more fretting out. Plays like the when I bought it. 😁

Just refilled it after three weeks, and it appears to be exactly as claimed. Left in the soundhole of a guitar that stays out in the heated air, and the guitar seems happy with the process. I was concerned about the Fishman wiring and it sitting near the output jack but it looks like it coexists peacefully with the electronics. I would put this in the case vs soundhole for an enclosed instrument, but if it is a daily player drop it in and forget it for a couple weeks.

Zen & the Art of Humidity

Moisture Content. Using your guitar as a hygrometer

Only humidify when your guitar needs it. Not all the time. Too much moisture can be equally damaging.

Only humidify when you need to

Drop in the humidifier when the action gets too low, and remove it when that sweet action returns.

If you keep your guitar in a case, monitor the humidity inside the sound hole. When it drops below 45% RH you will know it is time to humidify, and when it exceeds 55% RH you will know it’s time to stop.

Finally, don’t be fooled by the outdoor humidity. Relative Humidity is temperature dependent. As such, heated indoor air is often much drier than the air outside.

Feel the Action

In severe cases you can see a dry or swollen guitar just by looking at the profile. But long before you see it, you will feel it when you play.

Too much Moisture Content will cause the bridge to lift, resulting in high action making it much harder to play, while too little, will cause the bridge to sink, lowering the action and causing fret buzz.

The sound of the guitar is also another little tell-tale sign, albeit less obvious. A guitar with the right moisture content will have a fuller sound than one that is overly dry.
