Boveda BVMFK-SM 2-Way Humidity Control Kit - Small

This is a great product to keep your guitar at the proper humidity seeing I live in Southern California it can be brutal on wood instruments.

I bought this product based on it's claims to keep the case at 49% humidity. The inside of my case was always around 60-64%. After a few weeks of using this product it now is always at 70% or higher. I followed the instructions to a t. Even tried one in the sound hole along with one by the headstock as suggested. I would not recommend this to anyone in a humid area.

This kit comes with 4 pouches and 2 cloth holder which hold 2 each. I keep one in my bass guitar case and it keeps the guitar in the perfect environment as to prevent anybcracks or warping of any kind to my prized bass guitar. Thanks again AMS the ultimate one stop shop for your instrument needs!

This works well and I bought this one for my electric guitar. I'd say it's comparable to the D'addario system, and since that one works well too, you're good to go either way.

Here in Michigan, winters are dry, and summers are humid. Not good for my guitars! I saw this Boveda starter kit that combats the dryness and humidity that really hurts guitars, and the kit's packs are keeping two of my guitars safe. Great product!

Appears to work.

I've been using Boveda for about a month now and it appears to work as advertised. Guitar was re-hydrated and Boveda is keeping it in the proper humidity range while in the case.

Great product

I use this product all the time and have had great success. I keep 2 in my guitars all the time; seems to help stay in tune, and definitely cuts down on body cracks and neck shrinkage.

Is it working?

This is a Boveda 49 for violin. I have it in my case and in the first cool, dry wave we’ve had since my purchase the humidity level in the case is 40%. I thought it would maintain a level between 45 and 50%, unless this is how it’s designed to work.

Must have for high end guitars

I have a couple expensive guitars, both acoustic and electric. Keeping humidity controlled is a must for long term care. I keep these in the case with the guitars. I've measured the humidity inside and it keeps it at 48-50% just as it says, depending on the case and guitar. I like the small holder that comes in this pack. I've tried the large holders and the leather one. The large pouches I don't use as often, but the leather one is great for the acoustic over the opening, since it straps onto the strings. They seem to last me 6+ months and I usually keep 2 in each case.

Nice alternative for similar kits at a good pricepoint

Boveda to my knowledge makes these packages for orther manufacturers too. You could say these are the originals. What puzzles me a bit if this kit is meant for two guitars (two satchels with four packets or just one. The manual says you need to put on satchel in the soundhole and one under the headstock. But what would you do with the small kit then? The kit from d'Addario has a satchel for one packet to put under the headstock. These only fit two. For now I am using it only in the soundhole for two guitars and leave the headstock alone.
