I'm worried that putting a 5 string Jazz maple / ebony neck on a Ash body might not be a good idea especially with the reinforced carbon fiber rods, what do you think? Any experience? On the other hand there are plenty of Fender J and Ps that are Ash - maple and I think are ok. I have a 4 string P and it's well balanced. Don't know about Jazzes 5 though - maybe they are Hard Ash? What do you guys think?
