I was previously happy with this but not anymore after taking it for a professional setup.
The luthier has informed me the neck is badly warped and this may be why Guild have fitted a very high bridge in the factory.
Also, the truss rod inside the neck is so short he can't reach the end of it to make any adjustments so the neck is arrow straight and can't be altered.
These issues have obviously severely limited the amount which the action can be lowered and then fine tuned.
Very disappointed. Have contacted Thomann to see how they may be able to assist as I want rid of this guitar.

My advice, steer clear. Obviously very cheaply made and corners severely cut on production.
