Mine was in 1969, I had just been taking guitar lessons for about a year. I had started playing guitar on my own in 1964, (8 years old)... after I saw the Beatles on the Ed Sullivan show, (like millions of other little boys).
The guitar is my old Les Paul, a 1995 Les Paul birdseye standard. I've changed the nut (nylon nut), bridge-tailpiece-studs (all vintage-correct Pigtail), 500k CTS pots, bumblebee caps and currently I have installed the (pretty awesome!) Monty's pickups.
