Hey guys, I'm having a problem with my acoustic. I have a Guild GAD-50 and the action on it is fine on the lower frets. However, the higher up the fretboard you go, the action gets higher and higher. I'm wondering what I can do to remedy this situation. The string height is uneven for some reason and I have no idea how to fix it and I don't want to screw it up considering I paid 750 bucks for this guitar.
Thanks
