Building Mesa/Boogie Part 6: MARK II & PATENT for Dual Mode foot switching amplifier 4,211,893

[@mjm33mjm]

I Purchased my '82 Mark IIb factory direct, as there were no dealers here back then. Ordered it without a speaker so that it could be shipped with UPS, then slipped a EVM 12 into it. 40 years on and the only maintenance its needed is the output capacitors replaced (twice) and the channel relay had to be replaced. I've owned a Mark III Hardwood, Mark IV rackmount, and a colorful collection of hot rodded blackface Bassmans and Princetons, but I always come back to my blond tolex Mark IIb. Thanks for the decades of memories its given me. Cheers!

Mister Randall. Never think we're getting bored when you divert to different subjects or stories. It's awesome to hear such an educated person talking about his passions and all these decades of awesome stories and achievements.. I must say i got here from another KZbinr talking about you and Gibson and i was redirected to your part 5 and no I'm on part 6 thinking that i definitely need to see all of your videos.

Randy, cheers from Czech republic. I've been reading your schematics and learning about amps since grand school and finally I became an engineer in electronics. If not mostly, then pretty much a lot because I fell in love with the mk.IV sound and I wanted to know everything about it. For me, you and your closest people are Mesa forever. I'm sad what Gibson is doing now, I'm much more affraid what they will do next... However, please keep doing these podcasts, I guess everyone like to know all these stories you can tell us.

[@TheGgreen100]

Randy, love the channel! I have to say, I'm sorry to tell you but I am glad you did not successfully patent high gain as as concept, otherwise the community might not have such an amazing industry of great guitar gear we have today. However, I couldn't be more grateful for your contribution to the community! I currently own and love five Mesa amps, not including ones I've owned in the past. Thanks so much for a lifetime of productive devotion to your craft, you've been at the forefront of innovation and creativity the entire time, often with the rest of the industry following your lead. You impacted the culture of the world at large in a measurable way, and we're all thankful for it.

Randall, it's amazing that you're doing this series of videos - I'd really love to know more about the 90s and 2000s Rectifier Revisions, as I'm sure many would! I have an early (in the 17000s serial, 'Rec 3 C+' on the PCB) 3 channel Dual which shares transformers with the later G revision 2-channel models, and it's a very different beast to my other 3 channel (in the 43000s) - I'd love to know the ins and outs of what caused a step-change in design or components, be it parts availability or tweaking to suit trends (the latter bringing the triple rectifier to mind!). Also, interesting to hear in a previous video about the perceived changes you heard in speakers as their manufacturing principles changed along the way! Thank you!

Hello Mr. Smith I had a mark II c+ short head with the 4 x12 EV and black shadow (eminence) . I have never seen another set of these black shadow with the knight on them. The magnets were as big as the Ev's. If you could talk about the black shadow speaker and speakers in general. I know you call a lot of different speakers black shadows. I received so many comments of this cabinet and the head of course. I sent you a resume in 1993 with a hand drawn speaker impendance switch and rotated tube board for easy access. You did send me a letter back thank you for that.

[@boco1951]

My Mark II b is a little monster! Gracias

[@doyle935]

I was in the Navy and operated the Mark 8 boats for one of my jobs. They have 2- 12 cylinder Detroit diesel engines in them, It would drive me crazy if the engines wobbled in and out of tune like a guitar being out of tune. I would get the engines screaming and had to back down on the Port side engine to get them to sound and sync up exactly the same. Ever notice in a plane sometimes you can hear the wobble of the engines not running in sync? Where Im going with this is Ive had a MarkIII for many years, there is sweet spot in one of the places that I play that I have actually marked the floor and put my amp in the exact spot so the room works with my amp, almost like the room is tuned to the amp. Yes it may sound crazy and probably is but thats ok. It only happens in this particular building. It reminds me hearing the Mark 8s engines synced up and while standing in the little Pilot house where you drive it. Everything is in perfect harmony with each other from the floor vibrations to the almost stereo effects from the room. I really enjoyed your videos and thank you for sharing your stories.

[@mattyankovich]

Hey Randy, I’m a professional musician and touring guitar tech from the East Bay/SF and I’ve had the pleasure of owning a number of Boogies starting with a Mark III when I was 15 years old, followed over the years by a single rectoverb, three channel dual rec, two channel triple rec, stiletto deuce stage two, Mark V, Mark IV, and currently one of the guitarists I tech for has a rig centered around a Badlander 100. Needless to say I am a huge fan of the brand and legacy you’ve created and these videos are such a treat to listen to on my nightly walks around the Richmond district and I wanted to thank you for taking the time to share all these stories. My best friend of 15 years was a long time employee at Wild Birds Unlimited out in Dublin, CA where he worked with Dave Stillson who to my understanding was around in the early days of Boogie. Just wondering if you have any stories involving Dave at all?

[@jbognap]

Mark IIB - my first and only Boogie. It had a fantastic clean sound, but as 19 year-old, I couldn't figure out how to get a Santana lead tone without messing up the clean sound. The shared tone controls limited me. I guess what I needed was a true channel switcher.

[@georgelincoln5041]

I want to know if you ever took the Mark II for a spin at sears point and how fast was it. I bought a new Mark III red stripe and had a hell of a night when I got home cranking that thing. Never heard an amp get to scream levels so fast. The next day when I got home from work I turned it on and all hell broke loose. Sounded like a big crash at Sears Point. I went back to the store in San Jose and swapped all the tubes and it still wasn't right. Called up mesa and explained to them what happened and I was told to bring it by. I lived in Hayward at the time. Got there at 10 am and sat in that pretty boring waiting room until 4 pm. Kept asking when I would get my amp. It finally came out and when I asked what happened to it, the guy didn't look happy and mumbled something. But it wasn't a new amp, so they did fix it. BTW it wasn't Randall that I talked to. I still play that amp to this day along with a few other mesa amps I've bought and never had a problem with it except squealing tubes on occassion. Thanks Randall for an amp that made all the gigs I played over the years so kickass fun. Double stacked the combo on a 1x12 closed back and it sure looked cool up there on stage. 🤘

[@AnonYmous-jp8uu]

Will you be getting into the Quad Preamp? That was the piece that introduced me to full shred in 1990 at guitar school. my instructor Theriot had one from his Scott Henderson lessons. I later got a Simul-Class Head and got to know Dave Sarge at Penn State.. Love your generosity. Thank you again. I did have a 100 watt Carvin combo in natural finish with basket front, and graphic EQ...and I knew where they got that idea

[@johnreilly9748]

I acquired an Acoustic 136 a couple of years ago, my buddies that have a restoration biz got it and the cab did have some water damage. It had been hanging around our rehearsal place for awhile and I asked about it they said it was dead and about to be trashed I plugged it in and it fired up no sound plugged in speaker out to another and boom! Put a new 15in bass speaker and use it as a bass amp! So it was a guitar amp? Sounds great for bass!

[@paroblynn]

How involved with the development of the badlander were you? I have many mesa products, some almost as old as me (my 83 IIc+) and many others, including the badlander series. I love them. Also do you remember Dave Sarge? He is who I went to when I’d get stumped and who I went to before I knew anything. These stories are outstanding and I’m so happy to see them. Keep it coming.

LOVE YOUR STORIES. If I may -- My respect for Hoboes. Knew a guy who was a real Hobo. Rode trains and had a big booze problem. Call him H. H also was trained by old school body men in how to weld and repair metal on cars and trucks. The kind of guy who scoffed at Bondo and literally did most repairs with a hammer, some solder and maybe a welding torch. So I hire him to do some bodywork on one mashed up fender. Put him to work in my garage , buy him lunch and leave him alone for 5-6 hours. H did a spectacular job -- just a little primer and color and the fix was perfect. I paid him his requested price and even tipped him 40 bucks on top (still was hundreds cheaper than any bodyshop). Then days later there was a disgusting smell coming from a trash can. I investigate and I find human feces very neatly deposited among about 20 pages of newspaper - folded up like a Christmas present. While this WAS gross it was the Hobo way. See H was too polite to ask to use my bathroom (which I of course would have allowed him to use) he took care of it on his own. He didn't drop trou and poop in my garden - no he did it the Hobo way. If you have ever seen the Skid Row sections of any major city H's way is far superior than what goes on now.

[@MenashaMunitions]

Loving the content! Thank you! Question - any info on what James Hetfields Mesa Triaxis "CrunchBerry" mod is? Is anyone still doing these mods? Read somewhere it's a phase inversion mod or something.

[@TheGgreen100]

Hetfield's Crunchberries amp is a IIC+ head with a "++" mod done to it. The mod increases the amp's gain. It's a different mod than the phase inversion mod he had done to one of his Triaxis preamps in his Triaxis rig. He wanted to blend the Lead 2 Yellow mode (IIC+ preamp) of one Triaxis, and the Lead 1 Red mode (Recto preamp) of another Triaxis. Normally, those modes are out of phase with each other, which means they sound bad when you blend them, so he had the phase of one of those modes reversed, which put the two modes in phase with each other, which allowed him to blend them properly. Also in his Traixis rig, he had a rack unit with two hidden Mesa 5-band EQ's, each wired to one of the two active Triaxis preamps.

[@MenashaMunitions]

@@TheGgreen100 thanks, wasn't sure if anyone ever confirmed the CrunchBerry modded Triaxis was indeed phase inversion - did a lot of digging but didn't find much. I have all the parts and pieces to build that rig, minus the 5-band (building my own) and the road case which was being built by Encore Cases until their shop burnt down in the fires this week.

How about when you copied the SLO pre amp to create the Rectifier?

[@TheChadPad]

Soldano based the SLO off of the Boogie Mark 2 and Marshalls. Everybody copies everyone else.

[@JohnWiku]

​​​@@TheChadPadin you had eyes in your face, you could check the schematics yourself, and you'd see that the Soldano SLO100 design HAS GOT NOTHING to do with a mark 2 circuit, it couldn't be more different 😂😂😂 Arguably it has ties to a Marshall style circuit, but it's clearly something beyond even a "hotroded" Marshall. So no, Mike Soldano DID NOT steal anything from Marshall, and much less from Mr. Randall over here. However, Mr. Randall DID COMPLETELY COPY, PART by PART, the Soldano SLO100 preamp design for the Rectifier series amps.

[@JohnWiku]

​​@@TheChadPadeven the Peavey 5150 IS a copy of the SLO100, but with an added gain stage and no cathode follower to drive the tone stack, as it gets driven from the 5th gain stage plate. So the 5150 is in fact a hotroded SLO100, with the first four gain stages copied part by part 😂😂😂

I think we all want to now about the Rectifier vs Soldano details and if Gibson really did fired you :) ?!

[@yessitsme6884]

Yes, the similarities between the SLO and Dual Rectifier are too numerous to be coincidental. Every new amp is built upon what came before (even the "Mark" is built upon the Fender AB763 circuit), but I'd like to hear the story there. I know Randall did say it was to be their take on the "hot rodded Marshall" thing. After all, the 5150 did copy similar bits from the SLO (but modified for higher gain, and later tighter gain), cause Eddie had Peavey work off the SLO as a starting point.
