I'm just saying that if you are buying a pair of decent quality mics you should definately have them matched because you never know what you are likely to record using them. Say he wanted to overdub some cymbals, or record his band playing live, or his aunt Mary playing the tambourine in the bathroom 😲 . Normally you wouldn't pay to have them matched, it would be done as a matter of course, but even so I'd say it was money well spent.
I use Schoeps MK4, MK5 and MK6 capsules with a pair of preamps for location work, but they are excellent for studio recording acoustic instruments too, especially strings.
