Doing a little research on an upcoming purchase. 1. Fullerplast....What is it? What does it do? 2. 75' used what kind of woods for the body? 3. 3 bolt neck plate...for what? How is it better than a 4 bolt neck plate. 4. Any reason why the neck pup is routed in a curve at the top and bottom and the bridge pup isn't? Thanks!!!
