The Biscuit by Astatic is one of the most sought after shells out there for a harp mic, and the Shure Black Controlled Reluctance Element is THE most sought after element. This biscuit has been customized by the legendary Chuck Gurney, who added a screw-on connector, totally re-wired it, and brought the element from good to great, as only he can. I imagine some in-the-know harp players are going to be seeking this mic. They will not be disappointed. It absolutely rocks. And it comes with a nice vintage brown Astatic stand, where you can display it when you are not using it.
Here it is through a Fender Bassman with NO EFFECTS.
