There is a slight proportional matter when you print out the blueprint. The pic is somewhat resized verticaly so you must adjust the vertical dimension to be as the real guitar. If you have CorelDRAW software, you can resize it acording to a dimension, let say, pickup cavity. Then, split picture onto two layers (because it to big to be printed on a single A3 page) and then print both pages. Join them in the middle and check with your JEM/RG guitar placed onto the joined pages. If it is not understandable, leave your e-mail and I will send you .cdr file.
