I recently mentioned to a few forum members here [like Bruce at Blue Bear for one] that I was expecting to get some of AKG's newly reissued C 451Bs in for evaluation/review. Well, they're finally here and right off the bat I've found these to have all the "airy" qualities of the original C 451s thus far. However, I still have plenty more testing yet to do with this microphone. So far, so good though and this I can say without any hesitation! The C 451B comes presented in a very classy looking wooden box and I think AKG has done a stellar job on this. From what I am initially hearing here, I suspect the new C 451 B would liven & sparkle up a darker sounding Martin Dreadnaught as only one example or be just perfect for mic'ing anything that has a lot of high end detail. Drum overheads come to mind as one of the useful applications along with most acoustic instruments as well [mandolin, guitar etc]. This one has a lot of shimmer going on! Great job they've done on this microphone-- Check 'em out. Me thinks you'll really dig them. Stay tuned for more on this mic soon. I plan to be pushing the envelope and go into different areas/applications than one might normally expect.
