D'Addario Guitar Dehumidifier System - Humidipak Absorb Kit - Automatic Humidity Control System - Maintenance-Free, Two-Way Humidity Control System For Guitars

Na 3 weken het ontvochtigingssysteem in de case en gitaar aangebracht te hebben, is de vochtigheid in de case met slechts met 1% gezakt. Zelfs nadat de binnenkant van de case eerst met een haardroger werd behandeld. Dan nog de vraag of deze minieme daling niet gewoon van de centrale verwarming is die nu in de herfst meer aanstaat !? In dat geval doet het zelfs niets.

No stress! When i l"m out over the road for 2 and 3 weeks at a time i dont have to worry about my guitars anymore. I started with the other guys sponge and built in humidity/temp digital display but soon realized there was just a little too much moisture going on where i store my guitars. This product covers both ends of the spectrum. I throw the other one in there sans the sponge to better monitor the humidity. Perfect combo imo. Highly recommend if you have expensive guitars and sit up at night about the wood warping ,shrinking or cracking.

I've been a D'Addario strings user since the mid-90s, refuse to use anything else. Buy a lot of their other products too. But this really didn't seem to do anything. After two weeks in the case, the humidity is the exact same, i.e. high-ish. YMMV, of course, but it was a waste of £40 for me.

This is an excellent product. Everyone who has an acoustic guitar should use these products.
