Guitar Humidifier Packs - Two-Way Humidification System Conditioning Packets - For Maintaining Proper Guitar Humidification Level - 3 Maintain Replacement Packets

I bought a pack of these just under a year ago, and one of the humidipaks is only starting to solidify now - so I find that super impressive! This is well over the three months' time frame stated in the write-up, so I'm surprised by some of the comments that these packs haven't lasted. I suppose it depends on where you live, the humidity/dryness levels, the type of guitar and case, and so on. I have a Taylor acoustic guitar and Taylor hard case. The system is simple and avoids the hazard of having to put water inside the case - which I really think is asking for trouble. Just put one under the stockhead and the other over the strings, close the case and it works its magic. I initially bought mine because my wife and I use a wood-burning fireplace in our home during winter months and it dries the air out like crazy. I don't know what your results will be but I highly recommend this product based on my experience. I've just ordered refills, hence my write up now. I also think this is especially useful for any beginners/improvers who won't know how to maintain their guitar using other methods.

Excellent idea. The guitar now stays in tune in it's hardcase and the tone has improved dramatically. Barely needs a tuning tweek from one week to the next - partly due to the setup but largely thanks to this device. Have been using it for some months now and no sign of drying out. May be different if kept in a soft case i guess. Only reservation is that the thin cloth container of the sound hole humidity pack is getting a bit dog-eared and is now catching a bit on the strings. Rectified if hung over all 6 strings instead of over strings 3 and 4 as instructed. A minor issue. Well worth the money if you've invested in your pride and joy. Will definitely get another in due course.

I really like this system and it's simple to use, no having to do water, sponges and avoid the hazards of water and wood meeting. This is nice, just put it in the case and put the other over the D and G strings, close the case and it'll work it's magic. However after a few weeks less than a month the single pack in the case started to solidify and tried to mix it up to get it too work. They last around 2 months, not the 3 months advertised, and they're costly to replace so it's a bit hard to like it in one way, so of the costs replacement sachets it loses a star. I would recommend it fully though!

Worked great on my J45 when moving around the Middle East with work. Much better and less messy than the water based products that you have to manually refill.

The sound hole pouch was poorly manufactured. It is a double pouch, made to hold two of the Humidipak packets. The double pouch is suspended inside the sound hole of the guitar by being placed neatly over the 3rd and 4th strings of the guitar, so that they can keep the guitar at the correct humidity. However, the double pouch I received had one pouch significantly smaller than the other and the Humidipak packet would not fit into it and was left sticking out. The double pouch would not therefore fold over properly, so is cock-eyed and sticks out at an angle from the guitar strings rather than resting neatly on them as it is supposed to do. Another example of shoddy workmanship from China? No! Apparently all made in USA. Very disappointing! I suppose I will have to put up with it, having already opened the bag with the Humidipaks in. And it wasn't exactly cheap either!

Excellent

I am actually worried these might be adding humidity when they are supposed to remove and control it. Before I started using them the case would remain at around 65% It says in the description that they will keep the humidity within the safe rate of 45-55% (they don't, it has only risen since I started to use them) I also only remove the guitar from its case when the humidity in the room is 60-65% I don't really understand how something can both add and take away moisture knowingly at any decent level in the firstplace. If anyone has some advice for me that would be great, all the information I find online​ is about adding more moisture, not taking it away.

With the weather in the UK being what it is. It’s hard to get a consistent humidity in my flat. It hovers around 45-60%. So this kit is perfect for my acoustic guitar which I leave in my Hiscox hard case. It allows my guitar case to be humidity regulated much better than my flat and gives me peace of mind that my guitar is nice and safe.

Na 3 weken het ontvochtigingssysteem in de case en gitaar aangebracht te hebben, is de vochtigheid in de case met slechts met 1% gezakt. Zelfs nadat de binnenkant van de case eerst met een haardroger werd behandeld. Dan nog de vraag of deze minieme daling niet gewoon van de centrale verwarming is die nu in de herfst meer aanstaat !? In dat geval doet het zelfs niets.

Rather than taking moisture out of my guitar, this product profusely leaked into my acoustic and damaged it (seen by the dark marks) Thanks D’Addario!

Must have in your guitar Case

Great product. Very dependable to keep guitar at correct humidity level. Great value from this seller

The best solution I have found for protecting my acoustic guitar. No filling up a reservoir, and even in the AZ desert it did its job. You can tell when you need a replacement - the bag gets stiff. Easy to use.
