Bandito Amps: The Online Mag for Tube Amp Lovers
Volume No. 10-3  March 2010    
Holy Jumbalai and Crawfish Pie Bat Boy: That's right gumbo brains, the wait is over. Feast your eyes on the newest and best amps available anywhere on the planet.
It's Bandy's Best of the Best Awards for 2009 (but, Bandy, it's already 2010? That's right, glad to see you're awake. The award is for amps that are being built and have been tested, played, put through the paces etc by real musicians. Here at Banditoamps, we don't review amplifiers that might be built, are on some drawing board, or only some dream or concept without real world, critical evaluation.  "Wow! Senor Bandito, you have once again stunned us with your beautiful word use.....How do you do it with a 3rd grade education from Our Queen of Perpetual Adoration Primer School in Puerto Obama Indonesia?"  Hang with me vatos and you can sound like an artistic phenom too!

Let's get started ahora aqui banditos with the Best Harp Amp for '09

Vintage47 Amps 1942 Oahu "Chicago Blues Tone Twin"
David Barnes, designer/builder   Guerneville, California
 
Let's start early and start strong amigos. How about Bandy's Best of the Best Harp Amplifier. That's right, nobody records pro groups without a top of the line harmonica amp. And David Barnes over at Vintage47amps has really kicked the caca outta this category with his gatolicious 1942 Oahu Chicago Blues Amplifier. Let's take a look.

True vintage brochure cover for the 1942 Oahu guitar and amp lineup. You will notice in David's comments that this beautiful amp's original name from '42 is not listed, and probably will never be known. It may have only been built with just a model number which was common for Valco Manufacturing, Chicago, IL. Oahu was one of several companies selling amplifiers built by Valco.

David’s remarks on the early Valco amps, his age and his tone beauty harp amp:

DB    I just turned 60 and I'm still multi tasking, phone and puter. Not bad for an old guy! LOL

Nobody knows what Valco called this amp in 1942 , it is just in a brochure introducing the new Oahu lapsteel and slide lineup (one archtop) of guitars and amps. The war broke out 2 weeks later so most of the designs were never produced beyond the protoypes they were building.  You can see a copy of the original brochure above. (editors comment: I think I speak for all of Banditoamps readers when I thank David for taking a vintage idea and making a true work of tonal art)

Valco never made a thing that was "blues" music specific, they were 90% lapsteel, 9% straight guitar and 1% accordian until they started building country western guitar amps for Gretsch (Chet Atkins) in the early 50's. That shift in direction morphed into rock and roll amps and guitars (Supro National and Airline) in about 1957-58 approx. The dark tone of the early octal valco amps just happens to sound good for playing blues style guitar, and especially for blues harmonica (harp).  I believe this was by coincidence and not by plan.

'Chicago Blues Tone Twin' is my Vintage47amps name for the amp and the way it is referred to in the upcoming Guitar Player and Vintage Guitar magazines who are both doing articles about my vintage reproduction amplifiers.


(editor's note) Notice here in the "business end" picture, that the preamp section and the output section are separate chasis. In the very early days of guitar amps, the designs were adaptations of early tube radios.  Because the wiring layout was not much of a consideration, these early amps were very "noisy".  In order to isolate hum and noise, amp builders were experimenting with seperating the preamp from the power sections to reduce unwanted noise.  Oh baby! you look so fine with your nickers down and your volume up....come to pappa.

David Barnes says, "Ride free and play to o                                               win with Vintage47amps."

Bandy's Best of the Best Award goes to the M100 Super Plexi Granger Amps for Best Adaptation of the Marshall Plexi Tone.  Curt Granger; designer extraordinaire, Birmingham, Alabama.

The Granger M100 Super Plexi and our tube amp hero, Curt Granger. "I'm bababababad, bad to the bone."


After Curt was notified that his M100 Super Plexi had won, he made the following comments: 

CG     It's an honor to be selected by Bandito Amps to be featured on their website. It's always gratifying when others recognize my work. The M100 SuperPlexi was inspired by my love of both the legendary Plexi amps of the late 60's and early 70's, as well as the players I grew up listening to, such as Eddie Van Halen, Jimmy Page, Jimi Hendrix, Eric Clapton, and many others. I actually developed the amp based on my personal 1973 Marshall Superbass, which I modified several times to make it closer to the Superlead spec. It was one of the last turret board amps before Marshall switched to the printed circuit boards for the Superbass. That's my "magical" amp, and what I used as a reference while developing the M100. The one word I hear used most often by my customers to describe the tone is "organic." I also added features such as bias test points and an external bias pot to make it easily serviceable. Overall, it's just a cool amp that I think captures that rock vibe very well. It's also very loud! When connected to a couple of 4x12 cabinets, played with a Les Paul, and cranked up, well, that's what does it for me!  (editor's note: I highly recommend visiting the Granger website  grangeramp.com  "no S in amp" and watch Curt make the big money with this she-demon. I especially like his You2b clip where he rotates his LP towards the amp face and she starts to moan like Jennifer Aniston does when she sees Bandy in his black sequined Speedo; hide the kids cuz she's gonna pounce like a tiger)

This 100 watt monster carries on the early JM tradition and a little more. It is built like a tank, based on tried and true circuitry, but features key component value selections that bring out the sweetest "Plexi" tone possible. Clean tones are easily achieved at any setting by rolling off the guitar volume. As with some of the vintage amps of the 60s and 70s, each channel has two inputs, one high and one low impedance, and a volume control. A (post phase inverter) master volume (Ken Fisher/Lar-Mar PPIV type) can be added to achieve overdrive tones at lower volumes (highly recommended). Each channel shares the standard Bass, Middle and Treble tone stack and Presence control. The inputs can be jumpered to utilize both channels with channel 1 being the lead and channel 2 being the normal voicing. The preamp consists of 3 ECC83S valves and power is rectified by UF4007 diodes to produce a punchy, tight powerful low end. The power supply filtering is based on the legendary 67-68 era "12000 series" amps, and this arrangement produces a great combination of punch and touch response. The power section runs on four E34Ls which produce well over 100 watts when fully overdriven to saturation. For the service-minded player, an external bias adjustment with low voltage test points (1 per output tube and 1 common ground) allows the user to bias the amp when replacing valves without removing the chassis.

Si mi banditos, Curt Granger's M100 Super Plexi is full bitch and sweet like Jennifer's thighs....smooth, taught and ready for action.  Be sure to catch Curt bustin' up the joint with his Plexi on his sound and video clips. Easy as pie to find them. Just go to the 'Links' page and follow the bouncing kitty to grangeramp.com (no S)
Next up for the Best of the Best Awards; Best Low Wattage Amp with Really BIG tube amp sound, The Bambino from Reason Amps, Anthony Bonadio and Obeid Kahn designers/builders  St. Charles, Missouri 



The Bambino was born out of a single design objective: to build a low power amp that had the feel and nuance of our favorite larger amps. We're pleased to say that the Bambino has met that objective and exceeded expectations!

The key to the Bambino's "big amp feel" lies within its power amp, where a pair of NOS 6AQ5 Beam Power tubes work in Class AB push/pull. Feeding the power amp is Reason's proprietary StackMode SM front end. The Bambino's Normal and Bright channels deliver a broad range of classic voices while StackMode provides an unparalleled level of control over the texture, gain and feel of the amp.

In addition to being a great low power amplifier, the Bambino has several features that take it's usability to a new level. A front panel switch allows you to select between the full 8 watt output or a modest (but still delicious) 2 watts. And a balanced line out with sophisticated cabinet emulation, allow for direct recording, re-amping or plugging into FOH for bigger venues. There is even a Headphone out with Level control for silent rehearsing and recording.

The Bambino is the smallest thing in big amps! Learn more here: Specifications Tube Compliment: (2) 6AQ5, (3) 12AX7
Output: 8watts switchable to 2watts.
Operating Class: Class AB Cathode Bias, Push Pull
Channels: Normal, Bright, StackMode
Normal - Volume, Tone, Pull "Thick" switch
Bright - Volume, Treble, Bass, Pull "Bright" switch
StackMode - Normal & Bright channels active, plus Stack Volume
Balance Line Out - Electronically balanced on a TRS ¼" connector

Head Phone Out - ¼" stereo out.
Level Control: For Line Out and Head Phones
Speaker Simulation Circuitry: Inductive load network, cabinet response emulation
Internal Load: for safe silent recording and rehearsal
Footswitchable: Two button footswitch is optional Downloads


Despite the Bambino Combo's diminutive size, it boasts a 12" Eminen
ce Private Jack speaker- no boxy "small amp" sound here! A front panel switch allows you to select between the full 8 watt output or a modest (but still delicious) 2 watts.

Want a plug and play combo with expanded usability? The Bambino Combo Deluxe has features that take it's usability to a new level. A balanced line out with sophisticated cabinet emulation allows for direct recording, re-amping or plugging into FOH for bigger venues. There is even a Headphone out with Level control for silent rehearsing and recording


Want to know how this gumbachi Bambino sounds? Go to reasonamps.com and get plugged into some really fine Obeid Kahn sounds through the baby maker. Who is Obeid Kahn?  He designs the Reason circuits, and our other pal, Anthony Bonadio does the very customish cabinet fabrication.  Here's Obeid with one of the 'babies' just making its' first cries of life.










"Bandy, I'll give you a ride in my Porche if you let me hear that Bambino sing some sweet tubatater music."  Gretchen is always tempting Bandy with exotic rides and skimpy clothing.  It's a shame she's so plain looking and Bandy never really pays much attention to her. Oh, the unfairness of natural selection and the heartbreak of never getting noticed.
 


Ok vatos, hike the ball and go LONG!  In the ever popular Vintage/Modern category, comes a screamin' piece of history that every serious tube amp man should own. For 2009, the V/M winner is the Kendrick Badassman 2410,  Gerald Weber designer/builder   Kempner, Texas (give me freedom, lots of freedom, under starry skies above, and don't fence me in)


Since the idea here is a modern amplifier that looks, feels, smells and plays like a vintage amp only better cuz it's MODERN, let's take a peek at the original '59 Bassman amp.

Here she is banditos, our second most famous Old Glory.....Sail on my ship of state, sail on



Kendrick 20th Anniversary 2410 BadAssMan

““It was 20 years ago today!”” Well almost! It has been nearly 20 years since Kendrick introduced the 2410 combo amp. In the late 80’’s people were using transistor stereo power amps and rack-mount guitar amplifiers! The 2410 was the first point-to-point all-tube guitar amp to hit the scene in over 15 years. It changed everything for the 90’’s. To commemorate the 20th anniversary of the introduction of the 2410, we will offer a 100-piece limited edition 2410 BadAssMan amp. These are serialized from #B001 to #B100. There are many improvements over the original 2410 such as:
•• 175 year-old, unbelievably resonant antique pine cabinet covered in two-tone lacquered tweed (nico-tweed with brown pin-stripe)
•• Beautiful, baked-epoxy, gold metalflake powder-coat faceplate with black epoxy lettering
•• All the standard controls found on the original 2410 (and the original 5F6A Bassman), plus Reverb! Tube/spring reverb ala Twin Reverb circuitry
•• 5AR4 Rectifier with special ““invincible”” circuitry. It will never go down during a performance.
•• Lead and Clean channel with better voicing. The Clean channel offers three-dimensional clean tones without scooping the mids. The Lead Channel gives up complex lead tones that rival cellos playing in unison.
•• Two 6L6, four 12AX7 and one 12AT7 vacuum tube
•• Kendrick Quik Bias system with external pinjacks (like Gerald Weber Signature amp), so you can set the bias of your tubes in about 1 minute using only a digital voltmeter.
•• Optional built-in Power Attenuator to bring the wattage from 40 watts to 10 watts or 2.6 watts.
Some of the features will be the same as the original 2410:
•• Four 10”” Blackframe speakers made from NOS Donal Kapi cones (original supplier for Jensen)
•• Custom-made cloth-covered wire, Custom-made epoxy glass component board, and custom-made paper-bobbin transformers
•• 100% Point-to-Point handwired construction. The circuitry will feature improved layout with all the components cleverly laid out with a minimum of hook-up wire (similar to the Gerald Weber Signature amp). This makes for a better sounding and more stable amp tone; just perfect for blues, country, rock-a-billy, jazz, rock, or fusion. And there are three inputs. One for the lead channel, one for the clean channel and one labeled BOTH. The BOTH input will allow you to blend both channels together to get those multi-amp, Stevie Ray Vaughan tones. You can actually blend the lead and clean channel!
With two decades of empirical wisdom gained from building thousands of tube amps, and with the wisdom and hindsight gained from servicing nearly 17,000 vintage tube amps, the 20-year anniversary ““Limited Edtion”” 2410 BadAssMan, will be our crowning achievement of what a four-ten combo amp could aspire to be. If you own an original 2410 Amp or 5F6A Bassman, I promise the BadAssMan will eat it alive! It is a Bad Ass.

Editorial comment:  In the early days of America, if you worked in a trade, you had to practice the trade and advance by showing you were mastering the intricacies of the work e.g. carpenter, painter, auto body, brick layer etc.  I grew up learning from master builders who were perfectionists on every job site.  No minute detail was ever overlooked and the customers had a 'thing of beauty' when we were done.  They were proud of their homes or offices and couldn't wait to pay us.  Well, you know, and I know that a lot has changed since the 40's, 50's and yes, even the 60's.  But Gerald Weber is a master builder in the old tradition.  Not one minute detail is left un-touched by him in his quest for tone perfection and vintage beauty.  This 20th Anniversary Badassman amplifier is truly a work of art.  Only 100 will be produced and that tells you that Gerald knows the world of high quality art as well as what makes a Tweed godess sing.  Excellent work Gerald. I can't wait to show it off at my next holiday ball.


Be sure you visit kendrick-amplifiers.com and check out the brand new sound clips of the Badassman amp.  Ok, banditos, in the past some have seriously questioned Bandy's grip on reality. You know, stuff like, "that b.s. can't be real!" and "this guy slings more caca than Bill Clinton at a cheerleader convention." But, I'm gonna get as real as I can possibly get right here, right now.

  When I listened to the new Badassman clips in Gerald's 'Demo Room' I was transported to another celestial plane.  Clip #3 began and I found myself in an ivory and gold chapel listening to angels sing and beat their wings.

   Then I floated down to #6 and there, on stage at the Fillmore Des Moines, was Jimi Hendrix and Jerry Garcia sword fighting with golden Stratocasters.

  If you're not afraid of the spiritual things in life, you better be going to the 'Links' page and get over to Kendrick-Amplifiers....Bandy don't lie!

Here's the big dog lookin' good with his popular Kendrick Tejas guitar.  Be sure to visit the Kendrick website and peruse all of Gerald's art work. And, if you're serious about learning more about tube amps, Gerald offers informational books, DVDs and you can even go to his famous 'Amp Camp' and build your own tube amp with his guidance. Say it ain't freakin' so Bandy!!!!! 


Best Fender Blackface Sound and Look Award goes to Allen Amps "Old Flame"   David Allen builder/designer

A lot of years ago, before your Bandito slipped into America on an innertube raft from Costa Rica, I had the pleasure of owning a Fender blackface Super Reverb. It got lots of use and played for thirty years without as little as a fuse blow. Too bad I needed some travelin' cash in the late '90's and sold her off. The guilt and remorse has been enormous and the therapy bills are kickin' my puchini.

But, the good news has broken out across the land for all of the lamenting, post-affair lovers of the Fender blackface amps.  David Allen is now building the Allen "Old Flame" which he refers to as a one-channel amp with strong Super Reverb tendencies.  I think that's his way of saying, I've got the Super blackface mojo available if you've got the itch for one?  And we all said, HELL YEAH!

So, without further Bandy "run-on" let's take a closer look.

I made a valiant attempt to get a picture of David Allen for the Awards Show, but he said he looks a bit too much like Kenny Chesney and he can't afford to have Rene Zelmabeaver stalking him again. Too bad.

Ok, we have more winners and they will be listed in no particular order. After two bypass surgeries, hemoroid packing, hair implants and a steal plate in my head, I'm lucky if I can find my trousers well enough decide arbitrary programming placements. Oh, Oh, Bandy's loosin' it again.....Yeah but he's more fun than that commie John Stewarts aka Liebowitz. Amen brother.
