Still loving my (almost) consecutive serial number matched pair of KM84s from 1977, on everything! Here they are recording my acoustic:

It's pay what you like, so you can download the hi res 24/96 .wav or .flac file for free if you like.
They work surprisingly well on vocals too:
Preamp on both is a Chandler TG2.
Don't discount Omni mics/capsules for acoustic too though. I was recently talking with mix engineer Stephen Barncard about David Crosby's first solo album, 'If I Could Only Remember My Name', (one of my fave albums), as I simply ADORE the acoustic guitar tones on that, and he told me he used AKG C-60s (a tube based SDC rival to the KM84), but with the Omni capsules, as it meant he could get in really close (less gain needed), with no proximity effect, and with less bleed, than the Cardioid capsules.
Neumann still make and stock the KK83 Omni capsules for the KM84 body, so I am gonna place an order for one soon.
