I started playing bass at age 12 in 1964. Among early influences, The Ventures and The Beach Boys. Fell in love with Brian's white on white P-bass. So much so, that when I had saved up enough money, I wanted to get one just like his. I could only find the Oly white with the tort guard, so I bought it, an April 1966 model. In all of my years of playing and going to guitar shows, I've never seen another white on white P-bass, with the exception of some MIM's in the 90's. (That guard was actually off white.) My question is - did Brian have some special edition? Change the guard? Have a one of? Or what? His was probably early to mid 60's or so. Love the white with the tort, but also still in love with his white on white. What say yee?
