D'Addario Acoustic Guitar Humidifier

It works! My guitar healed after using this for a month continuously! You just gotta fill it up everyday and eventually you'll find yourself filling it less frequently and that's when you know the guitar is getting better.

Works fine and very inportant product in wintertime for acoustic guitars

Dimensioni "giuste" per essere infilato tra le corde o tra Mi basso e bordo buca Ottima chiusura. Da consigliare a tutti i chitarristi che ci tengono a umidificare correttamente i propri strumenti nei mesi invernali (riscaldamento ambiente pericoloso !).

Hace su trabajo. literalmente la madera de la guitarra se "bebe" la humedad de la esponja en 1 o 2 dias.. es importante estar recargando para mantener la humedad correcta.

By far the safest way to maintain the humidity in your acoustic guitar. Their are other ways out their but this is the safest in my opinion. People in this review section don't know what they are talking about so don't judge this product based on these reviews. I admit that the product should not be priced this much i mean this is just a plastic cup with holes in it and a sponge. But good luck with your homemade experimental crap. I am not about to experiment on my guitar. And i don't think people who own an expensive guitar would either. The way this product works is you should have a hard case for your acoustic guitar. Open the cap and take the sponge out. Wet the sponge and squeeze the excess water until it is just lightly wet and not dripping( this is the most important part you don't want water dripping in your guitar). Place the sponge back in the plastic container and slide the whole thing in between D and G string and place your guitar in your case. Keep it inside for 24 hours and check if the sponge is dry if it is then repeat the same process again. If the sponge is wet at all after the 24 hours? Then your guitar is at the perfect humidity. You should take your room's humidity into consideration too. Too much of something is not good. Be careful and always check on your guitar while using the product as water can damage the wood if not handled properly.
