I suggest the OP give the Pao Ferro a try. I love my '18 Player with the PF board. Warmer than maple but with its snap. Great stuff!It's a shame the current MIM Player Series only come with maple or Pau Ferro boards (although I like Pau ferro more than Rosewood)...
Hard to top that! GHS Precision Flats are a bit less pricey though and still give the old school thump. That being said, the LaBellas are the real deal OG string from the era. Particularly the Original '54's. They're stiff as cables though so maybe not and stick to the FS ones as you linked to.So true. This OP's search is one of the easiest to solve though in bassdom! All he needs are three things, and he's still way within budget:
Squier Classic Vibe '60s Precision Bass - Olympic White
La Bella 760FS Deep Talkin' Bass Flatwound Bass Strings - Standard
Foam rubber - Wikipedia
Boom. Done.
