These mics are really good. The price point is not cheap, but fair. The neumann quailty is immediately present when listening to recorded material. Stereo recordings of acoustic guitar is a dream. Works well on strings/choir and piano as well. I use these ones on guitar in the studio all the time, and as grand piano mics for live use on all my gigs. They have a slight accentuated top and rolled of bass, which in most cases is just perfect. They are slick, and comes in an even slicker case. I strongly recommend these mics.
