the K and K that I've got on my guitars has five little contact mikes - so you get a spread of sound = rather than a bridge only job. it was about fifty quid, and it was a shock how good it was. having said that- I did get it fitted by a damn good luthier - Alan Marshall of Northworthy guitars.

Its an American company - so you will probably get it for the same number of dollars that it cost me in pounds. A couple of times, its blown martins and lowdens out of the water soundwise and its attached to a cheapo Faith Jupiter.
