Since it's time to check on the humidity in your guitar I thought I'd repost this great tip. Especially in over heated NY apartments, can you say dry, dry, DRY?
A sponge, plastic cover, string and a plastic baggie, all could have gone into the garbage. I certainly could have bought a 'new' guitar humidifier made in some far away place in a nice package that would have lasted as far as the store to my garbage. A humidifier like many things doesn't need to look nice, it needs to be efficient. The inside of a guitar isn't thinking about style, it wants a drink.
There are endless ways we can reuse, reduce and recycle! What's one of Yours?
