Guitars are built to take a lot of abuse, but occasionally they do get hurt (like when full-blown "rock stars" deliberately smash them onstage or when teenage "guitar heroes" act like, well, teenagers). And sometimes, like all of us, guitars can simply get sick, beyond what a simple tuning or string replacment can fix. If you've got a guitar that's feeling under the weather (a coworker's code for "I'm calling in sick, but I'm really lying in a hammock outside in the backyard because it's so nice and sunny today"), just google guitar + hospital. There's help out there for your ailing ax. We found 18 cases of Illstrat* in OhioLINK, and 83 in WorldCat.
