Martin 18AHG Guitar Humidifier

Does the job.

Just bought a 35 yr old acoustic guitar and strangely enough fell across humidifiers a day later. Having done a little research i settled on this one. It was unobtrusive,easy to install,just sits between the middle 2 strings resting gently inside the body on the struts.So the guitar can be left in the case,it looked like some of the others,more like a small drum, had to be inserted in the sound hole which could be awkward unless you constantly detuned to get some string slack,then retuning every time you wanted to play it etc. If you wanted to leave it just in the case with the guitar,you`d need a fair bit of room,which cases don`t usually have.My little stash area under the neck,is usually full of straps,picks little "tools " and so on. We live in the UK,so humidity isn`t really a problem i suppose,plus the "old girl" lives in the hard shell case mostly. But,we have central heating and the room can get quite hot on times. Guitar was expensive,so i adopted a "better safe than sorry" approach. The use does take a bit of application & effort on your part to get it "filled" and properly inserted.You can`t just soak it and bung it in,you have to pay attention to the instructions or you`ll do unintentional water damage & over humidify the thing,which is just as bad ! I`d probably advise,as the instructions do,get a proper humidity monitor too,which i will to set it up properly. But overall a quality piece of kit. It comes from Martin guitars too (which mine is) so you can rely on it being a good item.They know about guitars.

Built for purpose small price to protect your instruments

My Gibson J200 was dehydrated to the point of being totally unplayable. I followed the instructions and within two weeks it’s back to playing beautifully. I can’t recommend this high enough. I saw it being used on the Taylor Guitar site. It’s saved a very valuable guitar for which I am very grateful.

I use a lot of guitar humidifiers and wanted to try this one over other systems. I like the concept and simple idea of sponge in a rubber tube. I will definately use again as simple to mange its use.

I’m not convinced by all this it’s probably a better idea to keep the humidity in your house in the comfortable range around 50%

Easy to use and better than a lot of the 'in sound hole' humidifiers on the market. Would be better bundled with some sort of humidity measuring device but they can be picked up fairly cheap

My guitar was showing signs of drying out due to low humidity. Two of these restored the moisture into my instrument in a little under a week. Excellent.

Ottima fattura. Fa quello che deve fare

These are my go-to on all my acoustic guitars. They are the ideal in-instrument humidifer. I slide it in the sound hole between the G and D strings, and keep my instruments more vertical. These humidifiers are super easy to use and if you use them properly--and store your gear properly--bridge lifts, cracks, and other guitar ailments shouldn't be an issue for you.

Using on a few of our guitars. Works well!

Jederzeit wieder

La verdad me ha gustado, tenía muchas dudas porque goteaba mucho después de mojarlo y secarlo, pero quitando el exceso de agua todo queda perfecto y el color está muy lindo algo fuera de lo normal, yo lo utilizo para mi cello.
