Audi, lass:

While I'm sure you do more than just sound fine in the shower, I seriously do not recommend taking your guitar in there with you. If it is nylon-strung you will find it very hard to keep in tune; if steel, your budget will be seriously impacted by string replacement costs, not to mention having to get a whole new axe every time the old one comes unglued.

Kendall, now, is kinda high strung, and I have always enjoyed watching him come unglued, and it costs less. Why not take him into the shower instead? He'll be happy to hear you sing your shower song while he warms up. I hope you have a large hot-water tank. Do let us know if you follow this friendly advice how long it takes for him to come unglued.

Best regards,

Amos
