This Yamaha from the 1980’s has had a hard life living in direct sun in a room over looking the ocean.
So many cracks in the soundboard you can drive a truck through them.
Strings and tuning pins have tons of rust I was afraid strings would pop!
The ocean water had turned these brass wound bass strings green.
