Description

Continue to protect your investment with replacement packets for the D’Addario Two-Way Humidification System. The D'Addario Humidipak System is the only maintenance free, two-way humidity system for guitars. By adding or removing moisture on demand the Humidification Control System automatically maintains the optimal 45-50% relative humidity level within a sealed environment (your instrument case) — the ideal climate for wooden instruments. The technology behind this product eliminates humidity concerns regarding seasonal changes, geographic location, temperature, or other factors without any guesswork or mess from refilling the humidifier. It is essential to humidify all wooden instruments. Lack of humidity can cause warping, cracks and other serious damage. The D’Addario Humidipak System packets last 2-6 months and then once they become firm, you simply discard and replace them with the refills that come in the Humidipak Replacement 3-Pack. No water, no drips, no mess, nothing to maintain. Replacing the packets in the Two-Way Humidification System is a necessity to maintain the stability and playability of your instrument. For over 20 years, D’Addario has been leading the industry in innovative and problem-solving products that serve musicians worldwide. D’Addario Accessories are proudly made in a state-of-the-art manufacturing facility in the USA to the most stringent quality controls in the industry.

  • Perfect Hydrating Tool, Easy!
Style: Maintain Size: 3-Pack
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. ... show more

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

  • Maybe not for everyone
Style: Maintain Size: 3-Pack
I've been using other various humidifiers, the "sponge type" for years. You do have to keep them moist and be a little careful with them, but they are inexpensive and work, well actually. The D'Addario ones I've been using for a while now and this is my first refill and I'm not that happy with them. I use my guitar regularly, so the case is open and closed often. Sometimes it's left open for a while. The arguably moisture from these gets wasted and they don't seem to recover. They are expensive compared to alternatives. So basically, I don't think they are for everyone. If you have a vintage / expensive guitar kept in a case and have a pretty constant moisture level, this is probably the way to go. It would be good protection and less maintenance. ... show more

  • Humidifier Packs are a simple, powerful, affordable way to protect your guitar and your investment
Style: Maintain Size: 3-Pack
Anybody who has a nice acoustic guitar knows it's a delicate thing, made of natural wood. If you don't humidify that wood, it will crack, ruining the guitar or necessitating expensive repairs. The Daddario Humidifier Packs I've used are amazing, easy, and effective. They last about 6 months and AUTOMATICALLY keep your guitar (if stored inside its case) at an ideal 45% humidity level. Just put one of the 3 packs that come in the box under the headstock of your guitar; and hang the other two -- like a saddle on the back of a horse -- over the strings. That's it. I like this humidifying solution MUCH more than the 'sponge' or 'soundhole' humidifiers, which -- even when inserted properly -- stretch your strings to the side to make room, and are sometimes prone to spilling water. I love my Gibson guitar, and I love knowing it has plenty of humidity in the case. ... show more
