nearly any C414 can work in the situation you describe, but typically it would not be my first thought when approaching violin
though have recorded more then one bluegrass ensemble with a single C414 (well DI'd the bass or used SM57/MD421 on amp if doghouse was amp'd, if possible)
I've used a C414 in figure of 8, mismatched SDC, LDC modified M/S recording a bunch and in this situation it generally depends more on the room then the instrument as to how well it performs
But if I only had the 414's (one or two) I certainly would not hesitate to use them for a chamber music violin/bass recording . . . I might prefer K84s but think that to be a matter of subjective flavor rather then pure function. C414 was one of the first mikes after performance dynamics that I added to the locker and before I 'knew' better I used it effectively on a lot of acoustic guitar, mandolin, fiddle, accordion, banjo, jews harp, oud, bouzouki . . . first time i rejected it (in those early days) i ended up using an inexpensive (for the times) back electret sdc on a mandolin that I had initially tried a vintage LDC tube, migrated to the C414 with every confidence (after being surprised and disappointed by the tube for that particular situation) had my judgment shaken again . . . of course at that time I thought I already knew everything I need to know
of course there are different flavors of 414 and not all are created equal so caveat remains audition if possible
