I started the JT30 page back around 1994 as an AOL web page. I hand coded the page using notepad and tested it using Netscape Navigator. I originally put the page up as an advertisement for modifying and repairing JT30 mics. I found that I did not have the time to keep up with the orders so I stopped doing that. I collected lots of information about JT30s, Amplifiers and playing amplified Blues.

In 1999 I registered the domain JT30.com.

I wrote a few music theory articles and tabbed out some simple riffs and I have been getting slow but steady traffic ever since. In recent years my life has become busy, other projects have taken up my time, and FaceBook has pretty much replaced blogs, so I have not added very much to the site. I still play a little harp when I get a chance, but I hardly ever play harp at the jams.

I've done a few unexpected things. Most of the things that I've learned are self taught. The fact that I finished college and graduate school is testiment to the fact that I already knew the stuff most people went to learn. I only learn stuff that I'm interested in, and only when I teach myself.

I am retired. I have worked as a computer programmer since the days of Fortran. I write Science Fiction (and sell it). I keep bees. I have two dozen chickens. I play blues harmonica.

By the way, the picture to the right is over 60 years out of date.

Buy the Book!

I cleaned up my tab for Sonny Boy's Help Me and made it into a short book. There's a Kindle version for 99 cents, and if you buy the paperback you get the Kindle free.

Playing "Help-Me" In the Style of Sonny Boy Williamson II: A step by step, note for note analysis of some of Sonny Boy's Signature Riffs

I also write Science Fiction, so you can sample some of my best stories. Also available in Kindle format.

I began collecting data about the microphones used by blue harp players before there was an internet. I began organizing it into JT30.com in the late 1990s. I accumulated more stuff than I remember. This is some of it.

Harp Tab

A collection of songs and riffs that I’ve worked out over the years, plus some libraries of stuff I’ve converted to tablature. I’ve included most of the notes and instructions that helped me when I was learning to play blues harmonica.
