Hi guys. I recently acquired a used classical/flamenco style guitar. Solid top and no truss rod.
Fool that I am, I left it overnight in the car last week and when I went out the next morning the heat in the car was pretty full on.
Anyway, I took it back in. I can see that the neck has slightly bowed around the 7th/8th fret. Nothing too bad, but you can see it when you look down the neck.
As there is no truss rod, can this be fixed? Once the weather changes, it might right itself. I don't know...
I've ordered some humidifers in the meantime but will be careful with these too.
Any advice on how to care for these guitars with no truss rods?
