I always thought Jazzmaster type pickups would be somewhat trebly and plinky but the 65 pure vintage JM set I put in my JM build has more body and sustain than any HB I tried. It's definitely not what I expected. They take gain like a really great HB without losing any definition, and the clean sound is warm and not ice picky at all. The hum is there but it's not bad, even at hi gain. Is this typical of Jazzmaster pickups? They are all I'm going to use if that's the case.
