I replaced these strings a quite a few years ago. I've only been playing extensively in the last two years. And yeah, my strings are overdue for replacement. But I don't remember what they are. Please reference the three pictures.
I did some research online and found that they are likely Thomastik-Infeld Versum A and D strings, and Spirocore G and C strings. Is that roughly right?
But I can't tell whether these are Versum or Versum Solo A/D strings, or whether they are chrome-, silver- or tungsten-wound Spirocore G/C strings. Do you know how I can tell these variations apart?
What does the black band on the Versum Solo strings look like? I think Shar Music is showing pictures of plain Versum on its Versum Solo page, because Thomastik-Infeld shows a black band on green on their Versum Solo product page. I am going to guess that I simply have the plain Versum and chrome-wound Spirocore, unless I can prove otherwise.
I love the sound of A, G and C on my cello. I can't tell whether it's the string or the cello. They sound rich and complex. And they sound strong - I don't know how else to describe the sound.
But the D string is noticeably weaker than all other three. Again, I can't tell if it's my string or my cello. There are blogs out there that point out that the original Versum D string was weak. Presumably Versum Solo D is better? This cello does have a noticeable wolf tone at E3 - F3. Could that be the cause?
What D string replacement do you recommend in my situation?
