Boveda 49% Guitar Humidifier Kit, 3 Packs + 2 Holders – Large Instruments

These work well, and gets me out of the weekly chore of filling humidifiers every week in the winter.

As always Boveda has the best quality products and it was shipped very quickly with everything that was supposed to be in the package. This product is a 90 day fix it and forget it problem solver that allows you to keep optimum humidity for your large wood stringed instruments storage case regardless of the humidity levels outside your instrument case without dealing with trying to remember to re-wet messy sponges and allows you to avoid possible water damage to your instrument. It allows you to easily avoid fret sprout from shrinking necks or tuning issues from warped necks and so many other unpleasant, costly and likely damages to your instruments that assuming you are not a luthier can not fix effectively yourself, or perhaps you are a luthier, but would prefer to not allow the possibility of damage to your beloved instruments reguardless of the fact that you can fix it yourself. Then this product is for you! A elegant solution to an age old problem. I buy a new starter set to put in the case of every new guitar that I buy because it is so dry here pretty much round. Thank you Boveda! You have been my favorite accessory for instruments since I bought my first Boveda starter set with my first guitar! I hope you never stop making these products!

It seems to keep my violin happy and I prefer it to the Dampit (no exposed droplets). Decent value for money too.

They seem to work well. Arrived on time.

1 of the most frequent causes of guitar damage is inappropriate humidification. Either too high or too low humidity can reduce a $6,000 dollar high end guitar to a $6 dollar pile of firewood, faster than anything (with the possible exception of leaving it in the locked trunk of your car during 100 degree days - but thats just dumb). The Bovida large instrument humidity set is a nearly perfect solution to this problem. When humidity goes too high the packs will absorb moisture and protect your guitar from swelling and deforming. And when environmental humidity goes too low, the packs will release moisture, preventing the guitar from uncontrolled, uneven shrinking, which results in expensive to repair cracks in the wood. There is 1 caveat: if you live in an area which has a period of extreme sustained low humidity during the year, oe 49% humidity packs are probably not going to work for you completely. You'll be just fine 8 months out of the year. however from November through the end of February in the Northeast at least the margins from a pack at 49% cannot maintain sufficient humidity for most guitars. you'll want to swap in Bovida's 58% humidity packs during that. - they fit in the same holders- and you'll be fine during that time as well

Excellent product to save your string instruments. Keeps humidity in the storage case at a constant level.

Got this to raise humidity in the Ibanez gig bag in which I store my Ibanez bass. Our home's ambient humidity has averaged 25% in these winter months. To be fair, I'm asking a lot of a case humidifier, given that low percentage. However, at best, this humidifier has raised humidity in the gig bag by about 7 percentage points. That's a step in the right direction but is far short of the 45% advertised. This Boveda system might be more effective in a hard case. In the meantime, I'm working on installing a whole home humidifier to eliminate the problem.

The product works but if you live in Arizona with soaring temps and humidity readings in the single digits sometimes you will not achieve the 49% humidity in your guitar case. I have to add a 4th pack in my case at times to keep the humidity above 40%. They will also dry out much faster than the stated 3 months - sometimes in as little as 3 to 4 weeks. Given the expense of these, it is not cost effective in this climate so I only use them when I go on vacation and cannot manage the sponge humidifiers like Oasis or Music Nomads products. They also dry out much faster here but at least the humid level stays in the upper 40 to low 50's for many days.

I've been having problems with fret sprout on my acoustic during the cold months so I got (what I thought) were the holders for 3 humidifying gel packs. I also bought a 3 pack so I ended up with 6--I don't know why I didn't think the packs were included but they were. The packs are so thin that I was able to double up and put in twice the amount in the holders. 2 at the headstock and 4 in the soundhole instead of 1 and 2 respectively. I figure with double the amount of packs on my case the less amount of work each pack has to do to keep the relative humidity at roughly 50%. It seems to be doing well, despite keeping my guitar in a padded soft case rather than a hard case. When I take the guitar out I put the humidity packs back in the case and keep it closed. I'll probably be able to use them until the end of this winter and start with fresh packs next winter, about 5-6 months total. That's a long time so I'd say that's pretty good value. They're just simple cloth holders. Not a fancy design but they do what they intend to. Stick one behind the headstock in the case, drape the other over the strings and into the soundhole. Never had a pack fall out inside the body... My old humidifying system was a travel soapdish with a few holes drilled into it and a damp sponge. This is a nice step up.

Disappointed for its performance. Only achieved ~60% for humidity control.

ヴィンテージギター買ったのですが、トラスロッド緩め方向余裕なしの格安個体。ネックが動かない対策何かないか調べてたらこれをケースに入れて保管するようにとのこと。高かったがケース内を適度な湿度に調整してくれるそうだから期待をこめて5スター。

J'ai essayer ceux de d'addario ,je confirme que les boveda sont supérieur.En terme de durabilitée ainsi que les pochettes sont d'une bonne qualité.Maintenant j'utilise seulement cette marque.

I purchased this for my Leho Solid Mahogany Ukulele. It's my first solid uke and I wanted to make sure all is well. I've used Boveda products for a few years now, mostly for my classical guitars, and have never had an issue. They work as advertised and have served me well. I do wish that they were cheaper, but given the frequency of replacement, it's not really an issue. 5/5 for the product itself, however a 4/5 for the price!
