Kyser Lifeguard Humidifier - for acoustic guitars

I love these things. I have one for each of my guitars. (NOTE: Make sure you get the correct size. Measure. My two smaller Martins needed the "classical" version; my larger martins and Gibson needed the regular size.)What I love is that it holds the humidity inside the guitar. This is especially useful if your home is almost humid enough but not quite. You can leave your guitars out with this in the soundhole (however, if it gets below 30%, I either humidify the room or put them in their cases and humidify the cases).I have these in the soundholes most of the time. If they're in the case, I still have them in the soundholes, but then I also stick in a Herco clay humidifier or something else in the case. The case itself sucks up humidity, as does the neck. But, primarily, what needs humidity is the naked wood inside the guitar, and that's what these do.These can actually also help protect your guitar from too much humidity, too, though I'm not sure how effective they are for that purpose.Some people have complained about the rubber discoloring their guitar. I have not had that issue or experience at all. Others have complained about leaks. I also have not experienced that. Don't overfill the sponge, and it'll be fine. (You can even overfill it somewhat and it's still fine.) As for the rubber ring, some folks take it off. I have left mine on, as they are intended. It works great.

This is the simplest, easiest to use humidifier for the majority of accoustic guitars, and is very effective especially when the guitar is kept in its case. It is a snug fit for most guitars but for a few which have smaller diameter sound holes, there is a problem getting the humidifer in. For my 30 year old Guild, the Kyser fits snuggly and stays in the sound hole except when I play. For the Taylor it fits too tightly so I slide it in most of the way, keep the guitar in its case and keep the case laying flat on a wide shelf. That way the Taylor is kept humidified.I've tried the wick and reservoir humidifiers but the Kyser is easier to fill and more effective.

Humidifies from the inside. Does good and important job. A little fiddly to insert. But once figured out it's easy enough. Important! If you use an inhole tuner, or an internal amplification control this will interfere and can't be used. I like that you can humidify without having to leave your instrument in the case.

I've found that if I put my guitar in the case, I play it a lot less often. Whereas if it's on the stand or hanging on the wall I pick it up constantly. Still wanting to care for my instrument, I struggled with humidifiers that sit on the strings or are designed to be employed with the guitar in the case, laying on it's back. This solves that.It's a little tricky to get into the sound hole, but it's not the end of the world. I've found that I just need to ensure that the rubber gasket stays outside of the guitar. If it tries to go into the body, it gets jammed. You also need to be careful that it isn't too saturated with water. If it is, when you fit the humidifier, you will invariably squeeze it and dribble water all over the finish. I find it best to soak it then squeeze out excess water right before I'm going to be playing with it for a while, then when I'm done playing, it will have dried enough that I can carefully put this in place without dripping water all over the finish. Even still, the first time I fit the humidifier after filling it, I lay the guitar on its back on my lap and put it in place.On a final note, even in the arid desert of Utah, the thing stays moist for several days without needing a refill. Overall, I really like this product because it accommodates my methodology that keeps me playing.

This humidifier works great (my third or fourth one), but you definitely need a Herco- or other case humidifier for the rest of the guitar. I use these to keep the box humidity up for guitars on stands in my living area. Also great for keeping it stable when traveling with a bag for the guitar.

Humidifiers in wooden stringed instruments are a necessity. But they're also a pain in the butt....all of 'em. There's either a sponge (that leaks) or a syringe (that drips) or a container that starts to smell like mildew after a while. Humidifiers are a necessary evil.I use Kyser humidifiers because they're the least expensive alternative 'in my experience' to get the job done. Other humidifiers I've tried (some more expensive) create worse maintenance issue with fluids and their placement. . . .or the prospect of coming loose and bouncing around on braces. With the Kyser, I can wring it out, dry the plastic and then go through the awkward, flexing and bending gyrations to get it into the sound hole without leakage. These things could be designed just 1/8" larger in diameter and it would make a world of difference in installation. But, they are what they are. . . .3 stars. Ain't my patent. 'Can't change it.Anyway, these things manage to keep my guitars humidified enough to avoid cracks.

Again, this product works very well for my two Acoustic Guitars. One guitar is an Epiphone Acoustic dreadnought steel and the other one is a Washburn Classical Acoustic/Electric nylon. Two complete different hole sizes, so make sure to measure the particular hole of your guitar, so as to fit properly. Depending on your location (weather/climate), you might have to replenish the water in your humidifier 1, 2 or 3 times per week. Also, I have both of my guitars always standing up. If you save yours in a case while not playing, the water replenishing should be less. Cosmetically, the "Kyser Humidifier for Acoustic Guitars" looks pretty cool installed and also when not in use.

I have Kyser humidifiers for all my dreadnaught guitars. Works well, Dave Dull from Martin also recommended these. Unfortunately it seems that Kyser is not producing the humidifiers anymore, a few are still available but mostly for classic guitars (smaller soundhole). Have to refill these every 7-10 days. In my opinion better than all the other available systems.

The humidifier is great, I feel that my guitar will be better preserved with this new humidifier. I still keep a humidifier in the head stock part of the case though. The only suggestion I have is for some way of knowing when it needs to have more water added, hard to tell by feel, maybe some indicator could be added to the top. Also, don't drop it inside your guitar, it is a little tricky to retrieve. Overall I do like this new piece of kit.

Bought this for my guitar that is always out of case sitting in the living room for a quick play.Fits the guitar hole but I cant play guitar while it is in. And it's not so easy to be taking it in and out all the time. Other than this, the material seems sturdy.

英語解説なので使い方が、なんとなくっていう感じです。

Great humidifier. Best money spent to protect your guitar. It is the easiest solution if you live in a cold climate. But please be careful. It can damage the finish if the unit is tight fitted. My brother damaged his Taylor acoustic by taking the unit out of his guitar. It can pull on the edges. The manufacturers don’t cover this if you damage it by humidifier installation and removal. Advise, Do Not use this on expensive acoustics. I use the Kyser humidifier on all my Fenders, Yamaha and Takemine guitars. Taylor’s and Martin’s use a display case with humidity control. I’ve had my share of guitars drying out. Take care of yours.
