Herco Jim Dunlop Guardfather HE360 Guitar Case Humidifier

There is not much to say about these little things. They are inexpensive ($4 on Amazon) and they WORK! This is basically a sponge (actually it's clay) in a little can, that keeps containers or guitars in their cases from drying out. You fill it with water and set it in your case or container. It does not spill or drip. You can't adjust the amount of humidity, or how fast or slow it humidifies the space like some more expensive products, but then in many cases that is not needed. If you're a cigar aficionado and need to keep your precious Cubans exactly 72% humidity, this is not for you. If you have some herbs or a musical instrument you just want to keep from getting to dry, this is the ticket. I will buy more of these. Depending on the humidity of where you are, it usually last around 2 weeks before having to refill. If kept in a small container or jar with herbs for example, it will last 3 or 4 weeks.

It is a pot of clay that slowly vents off its humidity after being 'watered'. Pretty lo tech but works way better than other methods and can keep humidity in your closed guitar case for over a week even in a dry environment. Same principle as clay disks used to keep brown sugar / molasses flexible in the jar - ask your grandmother.

Seriously useful in the recent heatwave. Kept my lutes save in very very dry conditions.

excellent produit pour protèger nos guitares

Ho acquistato questo prodotto perchè consigliato da un amico, prima non ne conoscevo l'esistenza. Contrariamente ad altri prodotti simili non si mette all'interno della chitarra, ma nella custodia ( molto meglio). Il funzionamento è semplice: basta tenere inumidita la pietra che c'è all'interno; quando si asciuga si ripete l'operazione. Io ho una Ramirez: sulle istruzioni ( ho controllato dopo) è caldamente consigliato l'uso di questi umidificatori. Tutti quelli che hanno uno strumento in legno dovrebbero usarlo.
