Sounds like rectified nylon.
Thanks, Dirk. I sent you a PM a few days ago inquiring about your low re-entrant D strings for baritone. I was confused about what "low re-entrant" means. Since then, a google search led me to your description: D tuning with the 1st and 4th tuned down an octave, if I understand it correctly. I really like the sound sample of this tuning, but am a bit concerned about arranging music for this set up. Not always, but most often when I arrange a chord solo, I rely on having the high (melody) note at the end of the down strum when playing a 4-string chord. When for any reason this is not possible, or practical anyway, and the melody note, therefore, is otherwise imbedded in the chord, it does not sound as prominent. I'm wondering if it would be safe to assume that this tuning is better used in finger-style playing? Do you know of anyone who is using this tuning, who might have some videos posted on line so I can see and hear how they approach playing?
Also, returning to my original query, I'm discovering that not only do I prefer different strings on my different ukuleles, but that which strings I prefer is not as predictable matter as I initially thought it would be. What I mean is that I find that the string I prefer is not only a matter of the body size, scale, and type of wood used in construction, but it is more related to individual instruments. In other words, on some mahogany sopranos I prefer one type of string, and a different string on another mahogany soprano of the same scale length. Nevertheless, it seems there are always trade-offs: I like the sustain, but the C string booms or the A string sounds weak; not much sustain, but I can clearly hear the A string; and so on. What I liked about the yellow strings was the response of the 3rd (lowest pitched) and 1st (highest pitched) strings. I'm not sure that I would necessarily describe them as "balanced," rather the C and A seemed somewhat pronounced, so that the counterpoint of melody and bass notes was really nice for my way of playing. The trade-off would most likely be sustain, but the more I have been playing, and depending on the instrument, I find a lot of sustain is not necessarily a good thing - I'm talking about sopranos now.
I suppose I'm asking for a recommendation of Southcoast strings that may maximize what I'm looking, or listening for. Perhaps, a mixed set? I should probably note that what I had been hearing with those yellow, nylon strings, may indeed have been better "balanced" given that I was comparing them in mind to strings that may have been weaker on the high and/or low end.
Thanks.
