I bought a used CV-1 a few months back on EBAY. Now the action at the 12 fret low E seems a little high, about 5/32". Also I notice that I can slip a piece of paper between the top and neck from the sound hole almost all the way back to the end of the upper bout. I know these guitars have a new design for the neck attachment. Does anyone know if this small gap should exit? The guitar is a 2006 and not a second. It has a guild serial number.
