JF344 set, been on the bass for about a week, less than one hour of easy play time. Long scale .043-.100. I can do fanned frets, straight frets, 4 string, 5 string, rounds and flats.... but I can't do lower tension. I thought I'd give these another go, because the tone is incredible. If it was only one bass, it would be this set on my P bass. But I have 6 more that I play, and I just can't stop my heavy handed muscle memory on a dime. I have the plastic container but none of the marked packaging. Cut for a P-bass string through the top of a vintage bridge. No wear, and the silk is not frayed at all. $50 delivered. PayPal is fine.
