History of this page.

In the dawn of the World Wide Web (1994), Keith Graham created the JT30 page. It started out as a home page for modifying JT30 microphones. Eventually the page became a catchall for microphones and amplified harmonica playing. You can see these pages at: The Original JT30 Page

Now I have three pages for harp mics, harp tab and harp amps. I'm going to start another one just for learning harp.
