Hello from Spain
Hi everyone,

This is my first entry in this blog, and will be posting from Spain. I will try to post on DIY for harmonicas, amps and so on.
Here is a link to a very well known webshop in Europe where you can find harp mics.
They also have a good supply on harmonicas
They have their own brand called Harley Benton which normally is made in china, same quialty than the big brands but sensible cheaper.

On next post I will show my DIY box for harmonicas.

Satan and Adam on tour: August 12-17 + new lessons at Modern Blues Harmonica
Satan and Adam, the blues duo (now trio, with the addition of drummer Dave Laycock), will be making a run up the Eastern seaboard next week. This is the first time we have visited Virginia Beach, Philly, Portsmouth NH, Rockland County NY, and Atlanta in more than a decade. Thanks to new restrictions imposed by the Medicare facility in which Sterling Magee (Mr. Satan) resides in Florida, this may well be the LAST time we tour outside the South. So if you're one of our fans from the old days, or if you've heard about us but never actually seen us live, we hope you'll make a point of attending a show. I'm happy to sign harmonicas, t-shirts, etc.

Here's our itinerary:


8/12: Virginia Beach, VA - Jewish Mother (9 PM)

8/13: Philadelphia, PA - World Cafe Live (7:30 PM, with special guest Charlie Sayles)

8/14: Portsmouth, NH - The Press Room (9 PM)

8/15: Piermont, NY - The Turning Point (8 PM)

8/17: Atlanta, GA - "blue Monday" party for Atlanta Harmonica Enthusiasts (time TBA). For info, please contact Jim McBride:

Here's a recent video of Satan and Adam in performance at a country club on Kiawah Island, South Carolina:

And here's a video of me and Dave in our first public performance of "Crossroad Blues." I've adapted the harp part from Clapton's guitar part in Cream's live version of the song. I'm playing foot drums (made by Pete Farmer of Bellingham, WA) for the first time in public. I WILL be playing this song on tour. Sterling is sitting it out:

If you're a harmonica player in search of inspiration, you might think about checking out some of my recently-uploaded video tutorials.

Got My Mojo Working: The holy grail for many harp players. A song that you absolutely, positively need to know. This is a two-part lesson organized around a two-page tab sheet. First page is my adaptation of the "head" or intro that always kicks the song off; second page is a transcription of the first 12 bars of Kim Wilson's solo on Jimmy Rodgers's LUDELLA album--a kick-ass harp throwdown, decoded and reassembled. The head is within reach for INTERMEDIATE as well as ADVANCED INTERMEDIATE players; the solo is extremely challenging at full speed.

Gussow offers new video: "Crossroads Blues," Clapton-style, on harmonica
Just wanted to let fans of amped-up harp know about something a little bit different that I've been working on recently. I've always loved Cream's version of Robert Johnson's "Cross Road Blues" ("Crossroad Blues" when Cream does it), especially Clapton's remarkable-for-the-time refashioning of electric guitar into something larger-than-life. So I worked up a version of Clapton's opening 12-bars for harmonica, and added a primitive foot-stomp sound by plugging a wooden block into my 1955 Bassman. Here's the result:

My trio Satan and Adam is about to go on tour; this experiment worked out so well that we're planning to add "Crossroads Blues" to our set. I get to turn my amps ALL the way up! This would make any harp player very happy.

About that tour: please visit for a complete list of gigs. We'll be hitting South Carolina, Tennessee, West Virginia, Pennsylvania, New York, and New Hampshire.

Rick Estrin Blues Stencil
A while I created a series of blues stencils that could be printed out, cut up and used with a little spray paint to put Little Walter, Rod Piazza or B.B. King on your favorite pickup truck bed, the sides of buildings, or on the wall of your room.

Rick Estrin gave me a call and asked me if he could use the stencil that I made of him. It was based on a picture that I took at one of his performances and it really came out well. I was happy to oblige. Rick is one the best players out there and one of my personal heroes. He has always taken time to talk to me when he comes to my neck of the woods. He is a great guy.

I made a bunch of other stencil images, including a couple of Little Walter. Imagine my surprise when the Facebook group Harmonica 411 appropriated one of them without so much as a by your leave for their logo.

Here's my stencil:

Here is their logo:

My stencil is modeled on a famous Walter pose, but the 411 logo makes no attempt to hide that they borrowed it from me.

I admit that I based my interpretation on a famous photo so I guess I don't have much of claim to it. At least I reworked the original and did not directly copy it.

How To play the Harmonica: 12 Bar Blues

Monday, April 20, 2009 is Ten years old today.
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.

At one point I shut the site down because I was getting so many emails and requests for information. I later started it up when the internet got larger and other people did the same kind of thing much better than I ever could.

In 1999 I registered the domain

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 and other projects have taken up my time so I have not added very much to the site. I still play a little harp when I get a chance, but I never get to the jams and seldom find the time to go out to a show. I have tried to recruit guest bloggers, but so far there are only a few takers.

In a year or so I will retire and at that time I want to start working on the site again. I would like to tab out some of my harp favorites in greater depth like I did with Sonny Boy's Help Me. I want to give some step by step instructions for some of the mic mods that I do. I want to document some of the odd things that I've done with harp tuning. It will have to wait until I no longer have to spend my time making a living in hard economic times.

Tuesday, March 24, 2009 - John Cephas leaves on a high note
Several years ago I went down to Elkins, West Virginia to learn how to play harp at Blues Week. Probably the best part of this experience was John Cephas and Phil Wiggins. Their rich brand of Piedmont Blues struck a resonant chord in me. I keep their albums rotating in my play list even after 10 years.

John Cephas passed recently and he will surely be missed. Not just by the thousands of guitar players who were his students, but all of us harp players who can recognize when a good guitar man knows just the right thing to play behind a blues harmonica.

I saw Cephas and Wiggins every time they came north, which was once in a blue moon. John always remembered me and we talked fondly about the Blues Week barbecues and the concerts. He was a quiet and intelligent man. He told good stories and could pick the hell out of a guitar.

I always wanted to go back to Blues Week when my financials improved, and see John and Phil play on the porch until the wee small hours. I waited too long. John won't be going back. - John Cephas leaves on a high note

Setting Goals
I was looking through some of the older posts on my blog and saw one that may be useful to some of you. It's certainly as applicable in my own musical life now as it was then:

Do you have a 'study buddy'? Sometimes it can be really helpful just to have someone to talk with about your musical path & goals. I've been in a huddle lately with my "study buddy" over practice and it's gotten pretty interesting.

We've been talking about "S.M.A.R.T." goals. For instance:

S-pecifc [I need to learn my new band's arrangements of 40 songs, plus vocals on 12 of those]
M-easurable [I need to learn them well enough to perform them]I'll measure my success against the approval I get from my bandmates in our weekly rehearsal, and at the gig.
A-cheivable [I can do it - I've played 80% of them at one time or another]
R-ealistic [I want to do it, and I need to do it to be qualified for the gig]
T-imely [Our next gig is in early December, 6 weeks away]

Promise yourself a reward for acheiving your goal. Now, in the case of musicians, most of us feel that just having the opportunity to play is it's own reward, but when you set goals, it's a good idea to set a special reward for a special effort. My reward in this case will be to spent the money I get paid on a new axe , which is not something I usually do with gig pay.

When setting goals like this, "take ownership" of your goals by sharing them with a friend or mentor who will help you hold yourself accountable. You might even do this by publishing your goals - like on this blog, for example.

Break the goal down into action steps that make sense and fit into the amount of time you have available. If you schedule daily practice sessions, have a specific number of things you'll do planned for each practice, for instance:
Warm-up - 5 min.
Sing 2 songs - 10 min.
Play 3 songs with practice CD, 15 min.
Free Play - 5 min.
(Oh, yeah - keep it FUN)

Monitor your progress - check in with your self, your study-buddy, or Mentor on a frequent, regular basis. If you start to get off track, this will save you before things get too out of hand.

Finally, don't be too hard on yourself if you don't exactly acheve your goal. Instead, adjust your next milestone, congratulate yourself on the real progress you made by your honest effort, and recycle - start working on that next goal.

The more you do this, the easier the organizing process becomes - eventually, it may even start working it's way into your routine subconsciously.

Harmonica Enthusiasts! My first harmonica Blog! Who I am and what to expect!
Hello Humans!

My name is Hector, and as far as I know, I am the only Frog with his very own Blog.

I created this guest blogger account as a way to comment on the great material that I have seen on the BloggerWeb, but I also live a double life as a musician (check out my stuff here: so I hope that I can also share some of that with you guys.

I have been playing the harmonica for over a dozen years, and want to give back in the way that I would like to have seen stuff on the internet when starting out: With humor as well as a straight forward ease of use. The site: has a collection of my alter ego's tutorials. He is much taller and less frog-esq then I am.

This is just a quick note to introduce myself. I will be back soon with some more targeted topics/blogs and hope you all find them enjoyable! Until then, Hector here, signing off, ribbit, and happy harping! (oh yea, and if you see the Honey Smacks dude, Dig 'em.. punch him in the stomach for me... we are in a pretty fierce feud)

Do you collect microphones or work on mics? Do you attend blues harp events and take pictures? Do you know tips and techniques for playing harp that you'd like to share.
I need bloggers who are willing to post to a few times a month on harp related subjects (not spam). Your posts will reach about 10,000 unique readers each month. Let me know if you are interested.
Thanks, Keith

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.

There is a cool news search engine at Google and there is almost always something interesting about Harmonicas. Try a Harmonica Search at Google News.
There are interesting Usenet discussion groups at Google:

The Cable Channel CNBC had a small article on collecting vintage microphones on 3/28.
Microphone Techs! Here is a nice article out of Circuit Cellar Magazine on the D-104, the older brother of the JT-30. It has a great discussion on crystal mics and how they match to modern equipment. There is a project on how to rig up a little op amp matching circuit.

If you haven't been checking out BassHarps Gig list, then you are missing out on great harp playing. If you are gigging and not on the list then you are probably playing to a half empty house.
There is a Jam Session FAQ on the Internet. Some of it is old and is missing some of the best blues Jams, but it may be useful for finding a local jam. Another more recent jam list is at the National Blues Pages.
