I, too, had a '63 Jazzmaster (Sunburst) for my first electric guitar. My mom bought it for me in '66 after I proved myself worthy by playing a Silvertone acoustic for hundreds of hours and learning dozens of songs. I must have begged enough to drive her crazy. We had a chance at a Strat, but the Jazzmaster was a step higher in the Fender taxonomy and Jaguars were too pricey. I picked the Jazzmaster. It served me well, but when I hit my Hendrix/Beck/Clapton, et al., days, it wasn't so easy. Looking back, I'm sure it needed some bridge mods and I had no clue about intonation. Traded it for a new '68 Les Paul Goldtop with P90s. Would that I had either of those guitars now. Ain't hindsight grand?
