these travel in pairs, do you know why? because they just arrived fresh from the wizard in Austria ( MIKROFONSERVICE ) of akg microphones with ck12 brass capsules…. full mechanical assistance, electrical overhaul, capsule reskin ( only on one side..) acoustic alignment, they sound pretty much the same in all respects, could almost be called (MATCHED)....…….. for another 30 years, they will serve you at full capacity.. I don't know why, but lately this model with this capsule is selling like hot cakes, it is highly sought after and in great demand… even more than the vintage neumann u87.. (other category of sounds)…..…think they still use them in the famous Abby road studios in London!……. unfortunately there are no more accessories on this tour, so the sale is only for the microphones with the black box and the velvet cloth….
