All you need to know is the sensitivity of the speakers in
question, and the type of cabinet (open-back or closed-back),
and you can compare at will. Celestions (at 100d–(at)–W/1M, as a
hypothetical example) with a 30W amp will be about the same as
EVM12Ls (assume 103d–(at)–W/1M) in a 15W amp, as the 3dB difference
in speaker efficiency is equivalent to a doubling of power. You
can play a loud rock gig with a Deluxe Reverb, if you have a
really efficient speaker, like a Kendrick or EV. Conversely,
you can crank a Pro with the Utah-brand Fender speakers and
not be as loud as that same Deluxe….. Food for thought….

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.
