Hello Mr. HasAsZard, I finally installed my American made Fender Flatwound (9050ML .050 - .100) Medium Light set on my AMERICAN vintage 1972 Fender Jazz Bass. The strings fit well on my existing nut slots and I think they have the same tension pull as a DR Marcus Miller Fat Beams. The relief remained the same and I did not adjust the heights nor the bridge tunings,the intonation and radius are correct Fender specs. They are absolutely great strings. I am happy they fit without modifications. I hate adjusting truss rods on a vintage bass.

All the notes are very clear and I am very satisfied with Fender 9050 MLs. I don't think I will go back to rounds anymore. The ease of playing is great just right for what I am after for. I will play my bass every day and run through the whole range of chords and lines to see how well they will improve over a short period of time. All the Best! Bon Ruiz.
