The official '66 Jazzmasters had a bound neck, block inlays and a matching headstock but early production models had a bound neck and dot inlays. As someone who thinks block inlays just look "off" on a fender, but who loves bound necks, I consider myself extremely fortunate to have come across an ugly ugly refinished (we're talking orange house paint) '66 Jazzmaster produced in January. The refinish job garnered a VERY reasonable price tag (this was also before the Jazzmaster renaissance of recent years) and it's all mine. After getting a new paint job, this is my main guitar. For me, this guitar is the clearest and most concrete example of why a vintage instrument is worth the heftier price tag. The neck pickup like Pop Staples in a bottle, the vibrato arm works like butter and the neck feels like home.
