Thomastik Jazz Rounds short scale. These are 32" because they are made for "short scale with tail piece". Basically medium scale strings by most other manufacturer's standards.
They are the smoothest feeling roundwounds you will ever find, by quite some distance!
The short scale set is .042-.093 but the strings are perhaps even more supple/flexible than you would expect, even with these ultra-light gauges.
The short scale set is actually slightly higher tension than the long scale set, except for the A-string which is slightly higher tension in the long scale set... Thomastik gauges can be extremely weird sometimes.
Personally I find the long scale too floppy, causing fret buzz unless I raise the action higher than I want to but the short scale set is VERY nice, although very borderline light/floppy for my taste! I use the short scale set on an actual short scale bass (with a tailpiece). If you're gonna use them on a medium scale bass the tension will be slightly higher, which is this case is probably a good thing!
The tone can only be described as OUTSTANDING! Very organic, "woody", warm tone. The tone is ultra smooth but still plenty of upper mids presence to cut through a dense mix. It feels like you actually hear the tone of your BASS, without the tone of the strings getting in the way. The dynamics are very lively/bouncy. They're far the most articulate bass strings I've ever played. So much that they may need some time to adapt to.
But do NOT get these strings if you want zing or "clank". You won't get that with these strings. Also, they're not particularly suitable for digging in hard. These strings shine with a softer touch. And no other strings sound even remotely like them. They are totally unique and totally wonderful, IF you can handle the low tension and supple feel.
