Why does my guitar crack?
It is critical for you to know the potential causes of guitar cracks so that you can protect your instrument and avoid the recurrence of the damage. Low humidity can cause significant cracks because the acoustic structure is made using fairly delicate wood. Generally, the body will shrink due to the dry environment until it eventually fractures. To avoid this, consider using a humidifier in the storage room for the guitar. Naturally, external cracks and scratches will occur due to physical impact. Therefore, invest in a good guitar case and practice caution when the guitar is being used. Finally, ensure that the pickguard on your guitar is properly installed. If the placement is wrong, the feature will exert stress on the body and the shell will be damaged.

Short of stripping and refinishing there's nothing that can be done. Looks like extreme temperature swing kind of damage.

Hmmm... I've seen those same kind of cracks on other Ovation/Applause guitars. I don't think there's any easy fix. I'd protect the bridge and neck, carefully strip and sand the top, then refinish with clearcoat.

leave it alone. It doesn't affect the tone. You'll never see a 1970s vintage Gibson without finish checking.

every single one of my old Yamaha Dynamics has the same crazing and finish checking as this one does, so far...and some are over 50 years old...I haven`t had any trouble with any of them, and I own 29 at this time, excluding my old first run classicals and the other makers models I have.
