CAD is a sister division of Astatic. Astatic makes the CB and Ham type mics
and CAD makes commercial mics. They have the same products with a different
sales force. They CAD HM50 and the JT-30 and the Hohner Blues Blaster are
all made in the same room. They put different labels on them.

The CAD has a gold tone grill.

VC means it has a Volume Control. These mics are not sold without the volume
control anymore.




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.

The JT30 Page Popular links

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.
