I have a Taylor and use a Taylor case I bought these 5 years ago and only replaced them because they so old I was afraid they may leak. My guitar teacher took them for his humidor. No kidding these work amazingly well I tracked the humidity and it stayed perfect. A must own for any guitar owner Read more

Just make sure your guitar is in a fairly air-tight case. With that established, you're good to go -- this is great, easy to use, and although a bit on the expensive side for a humidification gadget, it absolutely does the job. Read more

I’ve used these every time I’ve flown with my Martin acoustic guitar. The pouches make using the humidifiers really easy, they fit really nicely in the case. And they do their job! They keep the humidity constant and this is a must when flying. Highly recommend Read more

This Humidification System is effective. However, I should give this NO stars for goofing around too much: this is the sixth revision of the Humipak, according to my luthier. The previous revision was total disaster. I bought one, and could not reinstall the bag of humidifying resin on the spine (like a report cover spine.) And I was not alone in this, even the luthier said he couldn't and he's a strong guy and I'm a senior citizen woman. So it wasn't just me. So IF YOU HAD the previous rev with the spine you slid (maybe, maybe not) across the bag, this is NOT like that anymore. The new revision has saddlebags attached by a ribbon handle. You slip the humipak inside the bags, no closure and stuff it inside your soundhole. (It barely fits in mine, I have a classical guitar. (An acoustic steel guitar will fit it better, they tend to have larger soundholes.) There is a third bag for the headstock area of your guitar case. Does it work? Yeah it works.I know it works because I ran a test to see if it works (once an engineer, always an engineer.) And it works better than the sponge-type containers that you moisten (daily) and put in the soundhole. Those do not diffuse the water evenly into the guitar body. I know this because my guitar got overly dry EVEN WITH constant use of that device. I ended up taking it in for repair and rehumidification and meanwhile, the second guitar at home was given this new humidifier (because you need a spare, you can see why: the one is at the shop and you're playing the other.) I ran an experiment on the humidification. I purchased a D'Addario Humiditrak - Bluetooth Humidity and Temperature Sensor to track the rehumification and steamed up my office at home with a cool mist humidifier going 24/7. While the Humiditrak is not a super sensitive device, I'm told it's within 3% and it tracked an immediate increase in humidity. The sponge device stayed at a much lower level of humidification. The guitar got up to 45% humidity and then started to drop again when I turned off the humidifier in the room, so now I know: 1. Use the Humidipak 2. Humidify the room you keep the guitar in, and play in constantly. I use a cool mist humidifer. Distilled water will keep the white dust down, or use the kind that has a filter to remove salts in water. 3. keep case closed and keep guitar in case UNLESS playing it. 4. track humidity and temperature 5. check packs for "crunchiness." Crunchy means it's dehydrated. You need to buy Planet Waves Humidipak replacements. Not cheap (there is some lore about rehydrating in a wet sponge equipped sealed plasticware tub with the old packs on the side not touching the sponge, but I have not tried this. You can find this method here and there on the internet. A pro guitarist friend of mine does it. If I were to try it, I'd run my humidification level check again because even though it might feel soft again (swollen with water) the humidification might not be effective. Stay tuned. One star off for bad designers who thought that last version was usable. Wow. Just wow. But this version is good and it is effective. I have proof. Read more

I purchase several things on Amazon and was giving pretty in-depth reviews. From this point on, here's the new agenda…. if it works as advertised, is well made, meets or exceeds the description, is a value, and arrives in a fair amount of time, it will get a "star rating" equal to what my expectations were/are. If it doesn't meet these criteria, then I will most definitely and descriptively tell the short comings of the products and you as a consumer will not have to go through the trouble of buying the product without some background knowledge. If the sell pulls that item and relists under another description, I will put the exact same review on the seller's feedback page. Sellers have done this a couple of times in the past, and I was true to my word then as well as now. DR Read more

Works Amazing! My custom tele neck, was shrunk, cold winter in a basement with only a gig bag. Placed two bags inside my gig bag for a month, kept it closed the entire time. Opened it up, the frets were like perfect, no sharp edges, the guitar was like brand new when I received it. I'll utilize these always. Just be patient, and keep the case / or gig bag shut for a while, and presto, it hydrates! So easy to use, and that's a huge benefit as well. Read more
