Hello all…..

Yesterday I was working at one of the local FM
stations transmitter sites. They employ 2 30k Watt
transmitters. Keep in mind that these transmitters are
*tube* powered devices. On each of the transmitters
is a meter for plate voltage and plate current. The
readings pretty much humble any guitar amp:

Plate Voltage: 12,000 Volts
Plate Current: 2.7 Amps

I was impressed.

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 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.
