They both sound great but uh, neither strike me as particularly lyrical in thumb position. (I am not an expert in period performance, but I think there is some debate as to whether or not Bottesini played gut strings.) As a listener, I would take any number of players using modern set-up's playing Bottesini. It's not that you can't play the entire instrument with the bow on raw gut. You can ... but if you are working in thumb position a lot, why not save yourself $500 or so dollars and a whole lot of trouble while sounding better?
ahhhh i dont know..
his playing is
beautiful..
shall we compare it to rinat? he played on eudoxa... certainly, they are different player in countless ways. but, to remove the artist and talk about strings exclusively, it is fair to say the raw gut example above demonstrates less width in the vibrato.
I don't think a tighter vibrato inherently means it's un-lyrical. it's undoubtedly different, and for sure i see where you are coming from: xavier foley can make his bass
literally sing, on modern metal strings (not even sure what he uses?)
but i think there are significant valuable trade offs for the raw gut in this example. the upper register is so vibrant on gut strings, and that shows here. it's never harsh, though. just very rich, quite complex, and clear.
but, for modern times and a player like me (i will play solos, orchestra, and jazz sometimes in the same day) i understand that the raw gut - though extremely cool, beautiful and valid - may not be a practical all-around choice.
if i had multiple instruments, without question one would be strung with such strings.
for now, i've got my fingers crossed that gamut is open to doing a custom set, or gerold starts answering emails
i am hopeful that sometime in the future there will be a readily available (im sure expensive, too) gut core, low tension, 'modern' string.
