SOUNDBOARD CRACK!

Cracks in the soundboard don't mean it's a Basket Case.  In fact, cracked soundboards CAN mean that the soundboard has maintained its curved nature (which is a good thing since the curvature or "crown" helps to project sound) but its lifelong desire to flatten out has caused a crack.

Nonetheless, cracks are usually not a good thing, especially when the cracks have separated from the ribs, and no attempt to repair it has been made.  This causes a buzzing sound when certain notes are pressed.  Whether or not the cracks are detrimental to the piano can only be determined by a skilled technician.
