Today I went to a local GC to look at a 1975 vintage Ibanez P Copy. I was questioning the authenticity of this bass due to the fact that the neck was very narrow at the nut. I know that Precision basses have wider necks that the Jazz basses do, but does anyone know if the 1975 Ibanez P copys had a narrow neck, or was this GC trying to sell a P body with a jazz neck on it? The salesman was telling me that was the way the Ibanez models were. I have never read anything like that before. Also, the neckplate has a serial # L75xxxx, so I am under the impression that it is a true Ibanez model.
