Humidification headache
Hey all,
I recently bought a Santa Cruz (early 90s) that I've been carefully humidifying and keeping in it's case (up here in Minnesota). This last weekend I took it out and noticed more dip of the belly between the soundhole and bridge and more protrusion from the bridge to the endpin than usual. Closer inspection revealed a crack, the ungluing of the middle seem on the top from the bridge and worsening toward the end of the guitar. My hygrometer in the case read 35% (the lowest I have seen) despite Oasis' OH-5+ being full and in place. I have taken this to my bud who's a pro. There's no structural damage, all the braces are in place, etc. I immediately added on of those planet waves sponge case humdifiers at first in the case and now in between the strings of the soundhole, in addition to the Oasis. It's been sub-zero here are things have only gotten drier. My headache- Now, I can't be the humidity in the case above 28% Both humidifiers are resting above the sound hole, and I'm now waiting on a filter to start using an old room humidifier in addition to the ones in the case. I have noticed a slight narrowing of the crack; it does seem to be improving. Why can't I get it up to the usual 46%? My only thoughts are that the guitar is so thirsty, none of the humidity is reaching my hygrometer (which I've even placed under the neck join) It is a cheap digital hygrometer, but I have tested it (at least as far as breathing and watching the humidity change, etc.) Anyone had this experience? |

I think I'd take the hygrometer out of the case, set it in the room, keep the door closed, and humidify the room to 40+%.

Are the sound hole humidifiers drying out fast?
EDIT: I am in Maine and have a small room (maybe 8'x5') with a room humidifier and it keeps the levels in the 40-60% range...so room humidifier is the way to go IMHO.

The highest mine got yesterday was 36 maybe 37 in the case. Which was better than the 33 outside of the case. But I also run a room humidifier, but my guitar room is not a closed off room. It's my family room that is open to the upstairs bedroom and open to the hall that goes into the main house.
I think my wife is going to order a whole house humidifier this week.

During a really cold winter the shop would have at least two or three bagged guitars. A couple, two three days should be all it needs. |

A couple thoughts:
I've found hygrometers can be very unreliable. I'd put two in the case and compare them. I keep two hygrometers in my guitar room (i.e. bedroom), and they often vary by 5%. That obviously won't solve your humidification problem, but it'll give you a better idea what's going on. I would resort to a home-made case humidifier. You can find several tutorials with a quick google search. Long story short, cut a bunch of holes in a sandwich baggie and stuff a wet sponge in there*. In your case, I'd stick one at the headstock and one at the lower bout. I'd use these in addition to your Oasis until it stabilizes. Check the humidity every day. It'll get there. *for my home-made humidifiers, I actually drill holes in a travel soap dish. Works perfectly. |

Hey guys, thanks for all your responses. Some great information. The humidifiers themselves are not drying out all the quicker than usual.
It looks like a may have to resort to the emergency humidification until I can stabilize things. I've got this "whole house" humidifier we use at our wood shop, wondering how loud it will be. Any recommendations on room humidifiers? Do you end up filling it every day? What if I go out of town? Caring for this guitar is starting to seem like caring for a puppy, ha. |

http://www.handcraftedguitars.ca/201...9/guitar-care/ It could be your case is chambered. Think of this when you place your hygrometer and humidifiers. Pay attention to this paragraph: "Cannister humidifiers – Buy these if yo store your guitar in its case. These have a fairly large reservoir that holds and releases a good amount of humidity. They clip into position between the strings and are held in place in the soundhole. These humidifiers will humidify the guitar from inside its body. One thing to note is that many guitar cases create 2 independent air chambers which are separated and sealed by the soft foam and/or material of the neck chamber. With cases like this, it can be a good idea to wrap a second cannister humidifier with a bandanna and leave it under the headstock to ensure the fingerboard is properly humidified. Do NOT attempt to humidify the whole guitar by leaving one or two cannister humidifiers in the headstock area of the case. The bulk of the humidity will NOT enter the body chamber in many styles of guitar case."

Fishstick that humidifer is what I was looking for too, thanks. |

I guess the "secret" is to make any temperature/environmental changes gradually. I let nature take its seasonal course and ease my instruments into a room slowly and carefully, though. Good luck, happy picking. |

Hey Flatpick! I'm just east of you in WI, and we've been experiencing the same sub-zero weather. There's definitely some good advice here in getting your guitar back in shape, but I've found that once a guitar becomes stabilized, I really need to use at least two if not three humidifiers in my acoustic guitar cases in this kind of weather. Since I own an old home, running room units just won't get the RH up high enough to make much of a difference (25% - 28% max). I also use a hygrometer right next to the soundhole to get a read on the RH in the case while shooting for a minimum of 45%. In addition to using an Oasis soundhole humidifier, I add these little guys to my cases. I just use one screw to secure it to the compartment area near the headstock and/or near the neck heel:
I've been using them for years with no problems, and they're easy to make. I'll agree that it's much like taking care of a pet or babysitting......LOL.....but it beats having guitar issues. |
