The Silver Bullet
Shure 440SL shell with 99B86 element (June of 1959) and vintage volume control from Greg Huemann at blowsmeaway.com. My new "go to" mic.
Rock Block
I heard a harp player using this rig on stage recently: A Rock Block guitar pedal/amp and a little Crate cab with an 8-inch Jensen ceramic speaker. The pedal puts out 1 watt of power, so micing it up in the big club was a must.
How did it sound? Like a swarm of angry bees. Inside a metal drum. I'm sure the pedal works very well for what it is intended (guitar distortion) but it was very buzzy and nasal as a harp rig. That little Jensen speaker could not have helped much.
The guy using this rig played well enough, and the crowd seemed to enjoy it. And ya know... That's all that really counts.

My Amps
My modest collection of harp amps (as of today, anyway). Clockwise from lower left: 1970 Fender Champ, 6 watts; 1953 Masco ME-18, 20 watts; 1991 Fender Bassman Reissue, 45 watts, Mission Chicago 32-20, 32 watts (in fixed bias mode). I think I have all the bases covered.
The order I acquired the amps is Champ, Masco, Mission, Bassman. Through the years I've had maybe two dozen harp amps, but these are the ones I hung with over time. The first harp amp I paid money for was an Ampeg B-15N flip-top full stack (used, in 1979); the most recent is the Bassman.
I cannot help myself -- All of them have been modified for blues harp except the Mission which is a custom built amp. When I bought that first Ampeg-- and many amps that followed -- I was frustrated by the tone and didn't have the foggiest idea how to improve it. And, I couldn't find anybody else who had a clue either. So I dug in and figured it out myself. The quest for tone can be a cruel mistress, but the payoff is sweet. NOTHING sounds like a good player blowing though a great amp. Y'all know exactly what I mean.

Harp Mic Project
UPDATES:
I won an eBay auction for a Shure 440SL mic shell, which is probably what this element came out of. So, it will all be period correct, for whatever that is worth.
I've never owned a vintage Shure bullet mic, so when I saw the 440 "Silver Bullet" shell on eBay I decided to go that way. It is already machined and threaded for a Switchcraft 2501MP screw-on connector. I need to see about putting an on/off micro-switch on it somewhere.
---
The mic shell arrived. Looks great! The small hole in the bottom is filled with epoxy and there is a grounding lug on the inside of the shell. I've ordered gasket and the 2501MP connector.
---
The harp mic project is coming along. Lower left is the gasket to hold the vintage Shure CM element. Next to it is the Switchcraft 2501MP screw-on cable connector. Now I need to decide between a simple on/off switch and a volume control.

Pedaltrain Jr. Pedal Board
At the blues jam I host on Sundays at Ziggies in Denver, some schmo dumped a full glass of beer into my pedal board and didn’t bother to tell me about it. When I got up to play the last set my pedals were a sticky mess and the wireless was cutting out.
The pedal board I was using was the Boss BCB-60, a big plastic clamshell case with foam in the bottom. The pedals just sat there marinating in the beer all night. (Yes, I know it was a mistake to leave it there. Lesson learned.)
I had a complaint about the big Boss board: It took up too much stage real estate. So after the beer douche episode I decided to order the Pedaltrain Junior pedal board with the soft case; about $100.
This is better. It is more compact and takes up less space. The soft case is easy to carry and has a pouch for cables and stuff. And any liquid spilled on the pedals will drain off. The Voodoo Lab Pedal Power 2+ power supply mounts up under the board, out of the way.
In the photo above the board is sitting in the open soft case, but on stage I remove it from the case and put it next to my amp. Anybody wanna buy a used Boss BCB-60 pedal board, complete with Roland power supply and patch cables? Smells slightly of beer. Make offer.

Power Supply for the Kinder AFB+ Pedal
The Kinder Anti-Feedback pedal has become an indispensable tool for many gigging harp players. The only complaint I hear from those who use the pedal is that it does not have a provision for an external power supply, so we are stuck using batteries. This is a pain for several reasons: The pedal does not have a battery level indicator to warn you when it is time for a new set. And when you do change the batteries you need to remove four small Phillips head screws and take the casing apart. Not very convenient if the batteries go out in the middle of a set.
- I used the battery snap cables because I wanted to be able to use the AFB+ with batteries if needed. Just unsnap the cables and insert batteries.
- From an economics view: 9v batteries cost about $3.50 each, depending on where you buy them. So, it's seven bucks to power the AFB pedal. For the cost of the Voodoo Lab power supply you could re-battery the pedal 24 times. If you get every hour of life out the batteries and they last, say, 25 hours of playing time per pair, then $169 could buy you 600 hours of playing time with batteries. But, I am also saving on the 9v batteries for the other 3 devices on my board. It makes economics sense to me, but I admit that it is a rather steep price for a power supply.
- Dan Hazen reports on Harp-L that he has done the same thing using two standard Dunlop power adapters.
UPDATE:
As of December 2012 I've gigged this rig dozens of times and it has worked perfectly.
For Sale - Original 1958 Bassman Amp
[This amp has been SOLD.]
Wyn Walke has a very nice amp for sale:
"The board hasn't been changed, tape label is Lily-signed, even the power cord is still original. Spkrs also all original, but the 2 left ones' voice coils are open, and need attention. Pretty common from what I understand.
Some crackly noise when amp first comes off standby, but when I plug in to Normal channel, crackly goes away and it sounds great. Bright channel works, but needs some attention. Tweed missing from bottom panel, some tear in the grill cloth. Amp was gigged in its lifetime, 3 small cig burns on top as well as the typical drink ring from having set a beer or soda on top. More pix available upon request. Amp is presently near DC area."
Wyn is asking $6700. Contact me and I'll pass your mail along to him.

A 12+8 Harp Amp from Bruce Collins

This is the amp Bruce Collins of Mission Amps made for Al Chesis. It is similar to my 1x12 Chicago “32-20” amp, but it has a 12-inch and 8-inch speakers. It uses a softer rectifier tube to bring the power down a bit and give it a saggier tone.
I played a set on this amp last night at Al’s blues jam at the Boulder Outlook. NICE! It barks some big tone with a hell of a bite. Nice attack. I used Al’s bullet mic with a CR element… a good combination.
The 12-inch speaker is the Eminence Cannabis Rex, which still needs a little breaking in. I know these speakers well, and after they get a few hours of stage time they freaking snarl when you spank them. The 8-incher is a Jensen P8R. It definitely cuts through the mix. I polled the audience after my set and everybody I talked to said they could clearly hear the harp even during a typically raucous jam.
The cab is a bit larger than my 5E3 tweed Mission amp… I think it is a tweed Super cab. It is still smaller and lighter than the backbreakers many of us use, and it stood up to a stage full of drunk and enthusiastic guitar players. Impressive.
Contact Bruce Collins at Mission Amps for price and details.

Hardware Notes

Line 6 Relay G30 digital wireless
I’ve now been using this wireless rig for a few months, and here is the lowdown: It is simple, reliable, and dead quiet. It sounds and works exactly like a cable. It is digital, not analog like most other wireless rigs. There is zero discernible latency. If anybody tells you there is a latency or lag issue with this rig they probably have an agenda (they want to sell you a more expensive analog unit).
It has a small body pack transmitter, so if you are in love with the idea of a transmitter hanging off the end of your microphone this is not the wireless for you. The transmitter has a belt clip, and I either stick it in a pocket or on my belt.
The effective range is said to be 100 feet, but I’m certain I’ve exceeded that distance and never lost signal. I’ve never had a dropped signal or any extraneous noise, or any coloring of my signal or anything. The thing just works every time. It is powered by two AA batteries, which last about 9 or 10 hours. I now use it for every gig.
Kinder AFB+ Anti Feedback Pedal
I’ve been wanting for years to borrow one of these for a long-term test, and I finally just went ahead and bought one on the used market. Most Kinder owners I’d talked to said it gave them about two more usable notches on their volume control before feedback. Some said it dirtied up their tone too much, or otherwise changed their clean tone in ways they did not like. Here’s what I found:
It works great. I’m not sure it changed my tone at all, except to the extent it allowed my amp to be turned WAY louder, which in turn allowed my power tubes and phase inverter to start breaking up in that cool harmonic way. Without the AFB+ my Bassman RI amp will start to ring at about 5 or 6. With the AFB+ pedal I can crank it to *NINE* without fear of howl, and the amp really begins to sing. I had never before heard my Bassman at 9.
I don’t understand the complaint that it changes your clean tone. If you want clean tone why not just play through the PA system and be done with it? The whole point of feedback control in amped blues harp is that we are walking around with an open microphone in front of a powerful amp, which is a recipe for squeal. If what you want is clean tone just step up to a vocal mic and have at it. Personally, I’d prefer some crunch and warmth.
I’ve read many comments in harp forums to the effect that the Kinder AFB+ pedal will turn any powerful guitar amp into a suitable harp amp. Uh, not really. If you plug it into a Marshall Stack or a Twin Reverb they still sound like crap and scream with feedback. This is an electronic device, not Harry Potter’s Elder Wand.
Fender Bassman Reissue Amp
The project Bassman amp has gone through a pretty extensive modification to make it more harp-friendly, without actually changing the hard-wired circuits much. The only mods that required soldering were beefing up preamp plate load resistors to deal with the 12AU7 tubes, and the installation of bias trim pots for the power tubes.
All the tubes and two of the speakers have been changed. After much experimentation, I use the tube scheme recommended for this amp by the respected author of the Green Bullet Mics website: I have vintage 12AU7 tubes in sockets V1 and V2, and a NOS 5751 tube in V3, the phase inverter. The rectifier is a vintage 5V4, and the power tubes are Tung Sol 6L6, which are biased rather cold.
The top speakers are original Alnico Blue from the Bassman (actually they are re-branded Eminence 1028). The bottom speakers are Weber 10A125-O alnicos.
The amp sounds good; I get lots of compliments on the tone. It is actually rather crunchy for a Bassman, and still retains much of the punch and brawn. It cuts through the mix all the way to the back of the room, and has tons of reserve power. The only drawback is that it is heavy.
The Kinder AFB+ pedal has made it a better, more usable amp.

Little Walter playing through a Masco amp
Little Walter often played through whatever amp was available. It is known that he played through Masco amps from time to time. The rig in this picture had two 1x12 cabinets driven by a cathode biased 2x6L6 amp. When Bruce Collins and I developed the Mission Chicago 32-20 amp we used my vintage Masco ME-18 amp as a starting point. The Mission amp owes much of its distinctive character and tone to the 50s Masco design. Megatone Amps has also produced a amp on the Masco theme. It's a good place to start. Little Walter knew something about harp tone...
New from WEZO
Here is the amp next to a tweed Fender Harvard. Nice compact size for such a powerful amp.

New Pedal Lineup

With my ’59 Bassman RI amp I’ve gone back to using a few pedals. Here’s what I have now:
Boss EQ7 – I use this only when I have a feedback issue. I prefer the tone without it.
MXR Carbon Copy Delay -- My guitar player bought a new TC Electronics Flashback delay (that thing seriously rocks) so I bought his MXR pedal. So far I’m just using it for single echo slap back, with the settings you see in the photo. It sounds good, really warm.
Line6 Relay G30 wireless receiver – I gave my old Line6 wireless to my girlfriend’s son. (He plays in a very good band in Phoenix.) Having been so happy with it I replaced it with a new Line6 digital wireless. Fantastic sound and performance. It is noiseless and simple. It has no companders like the analog wireless units (Samson, etc), so the sound is uncompressed and natural. It sounds exactly like a cable.
About the TC Electronics delay pedal… I haven’ tried it, but I am greatly impressed with the tone my guitar player gets with it. It is greasy wet without being splashy. Way different than he sounded with the MXR.

New from Mission Amps

Bruce Collins at Mission Amps is now shipping some notable new harp amps. They follow the same design philosophy used in my Mission Chicago 32-20 amp (pictured above), but with a few mods.
First of all, the chassis is bigger which allows for beefier 50-watt transformers. The new amps run with slightly higher plate voltages and produce an honest 50 watts of power at clipping.
The amp shipping now is a 3x10 configuration with a Weber 10A125-O speaker on top, an Eminence Lil’ Buddy hemp cone ceramic on the bottom along with a Quam ceramic speaker. I’m told the tone is stunning.
I have not had the chance to play this amp, but I have heard from new owners after they take delivery and gig it. They use superlatives to describe its tone and performance. Here’s a quote:
“The amp is the best and coolest sounding amp I have ever played and I currently have and have had sonny jr's, Harpgear, Clark, Magnatone, Premier's, Hurricane, and some others. They're just not in the same category as this amp!!”
Bruce is shipping the 3x10 and is taking orders on 1x15, 4x10, and 10+12. One well-known pro harp player has ordered a 4x8.
I’ll road-test the amp as soon as I can and review it here. You can contact Bruce at Mission Amps.

Harp Amp Project - Fender Bassman RI

Today I bought a rather well used early Fender Bassman Reissue amp, which dates from April of 1991 by the production code. The amp has a tube rectifier (not solid state) and the original alnico blue speakers, which are re-branded Eminence 1028s. I paid $500.

New Cable

I’m not so sure. I’ve heard that before but have never seen definitive evidence to support it. Chuck Gurney is a very well-known custom harp microphone maker who also makes and sells cables – all of them cloth covered.
I found a web page from Ovni Labs comparing and testing several instrument cables. Their top three picks were all cloth covered.
So what’s the deal? Is the story about cloth cables being inferior just an old urban legend? Chris makes and sells fine custom cables that are not cloth covered, so he may have a bit of an agenda here. I’d like to know what you think.

Power Harp
A fan at our gig last night called me "Power Harp." LOL... I think it fits. With this band (The Blues Allstars), I tend to play hard and imitate the guitar tone and lines. We trade a lot of riffs. It gets pretty far from your strict old-school blues harp style. Blues harp Nazis get the vapors at our gigs. They think I'm doing it "wrong."
