Boveda Music Large Starter Kit - (3) 49% RH Standard Boveda - Ideal Two-Way Humidty Control for MOST CLIMATES - For Guitars & Other Large Wooden Instruments

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.

Ormai non posso più farne a meno. Mantiene la corretta umidità nella custodia della chitarra. Indispensabile!
