Edit: Received a couple of responses already, so closing this for now. Will reopen later the strings are available... Hello, I have an old five string set of jazz flats, that I used on a 34" scale bass and 34.5" scale bass with no problems. I don't know how much use they've had, but I've owned them for maybe 5 years, and did not have them installed most of that time. My best guess is that I used them for less than a year total, but these should be assumed to be old strings. I have a set of Jazz Rounds for 5 string bass that I'll throw in for free. These are *really* low tension...for me, they are almost unplayable on a fretted instrument, but they make for a soft, slinky, easy playing fretless. Seriously, I wouldn't be surprised if this set could be tuned E-C... I'll sell them together for $32 shipped in the US, a few bucks more shipped elsewhere. Again, these are very broken in...don't buy if you prefer your strings new. Thanks!
