That's awesome.... Love Airbourne... Have em cranking most days at work 🤘

good content, looking forward for more from this series. Btw you left red panasonics, do you think they sound different compared to mustards? Thanks!

Airbourne clearly know what they're doing bringing you those amps!

Before had a more relaxed midrange and a little less gain. After has a more present midrange with better harmonic content and a touch more gain. Great improvements Jason!

You lucky bugger !! This will be a quite enjoyable series

Why can't Marshall make amps the way you do??

EPIC....weren't the old days awesome

Great amp

The Marshall "KERRANG" clearly restored, us Aussies are bless to have Jason , someone who really knows and understands these old Marshall circuits- tipping the Airborne boys will be inspired to write a whole lotta new riffs, congrats my man, you must be stoked to be resurrecting the arsenal of AUSSIE hard rock royalty..

On the fortin nameless plugin what I liked the most was not the "METAL" tones but how it cleaned up. Do you guys have any suggestion how to design the gain staging to achieve this? My current conclusion is that on the available Fortin-like scematics all the cathode sections stay the same! That has to be important, though I still don't know if I should go with the 820R or the 2k7. Then I know there has to be some chipping away at some points to tailor it and prevent some harsh buildup. Any suggestion is welcome, and I don't want to necessarily copy it, just understand what's going on. Also, weirdly I did not like the Cali plugin at all. (just putting it here, as a reference)

I saw Airbourne play over 10 years ago in a small club in Madison, Wisconsin. They both were using 2 Marshall stacks each. It was one hell of a loud and rocking show! Thanks Jason for the great work you do keeping these amps making the sounds we love!!

Thanks for all your love, effort and hard work you legend!!!!. Yes I have just finished a Rum and Coke, but nevertheless, very appreciative. Cheers.😊

It still amazes me how circuit design with capacitors,resisters ect ect can either give you a great amp or a shit one?? Its a science i just don't get 😅

Can’t wait to see the next videos. Any plate fed tone stacks amongst them.

Cool guitar

Awesome Jason, love this stuff

Nice one Jason. Looking forward to seeing the future videos in the series.

This is beyond exciting! So cool thanks for terrific content and products.

Great video. Love that tone. Cheers!

I've said it before and I'll say it again; if you want the best Marshall made today, buy a Friedman! 😏

Awesome stuff as always Jason.

I was just wondering the other day if you had ever taken a look at their Marshalls! Too cool!

i have had 2 74 sl,s, ..unicord of course, one a "rosemary" if you know, you know....a converted 34 and the other i had kt 88s. a beast.

Keep on keeping on Jason ,love all your work man ,I dont think you Amp techs realize how much your Appreciated ,especially because your a very good player and know what you want to hear ,cheers Jason !!!1

I have a Super Lead reissue (1990) that was modded by Suhr Amplification. It has no clean tone, just straight to break-up and I kinda wish it had some old school chime. It does however do some great metal tones without any pedals so I guess we just learn to love what we inherit!

Man, this thing sounds so great.

You are the Marshall Master!

I love the fact that they let the amp do the work for distortion ,pretty sure Angus does the same, a few of my favorite guitar players growing up did the same ,but I will say that if you can get the same outcome at low volumes to practice thats badass as well

My 2021 Marshall Jubilee's power transformer doesn't whine, but it hums annoyingly loud

Seemingly subtle sonic improvements but when all seven get taken care of what a sound it’ll be. Great sounding amp. That center tap ground. Lol. But hey it works. Curious if that ground scheme will go in the other amps. Looking forward to this series.

You’re doing God’s work my friend.

Look forward to viewing the upcoming vids Jason.

I'm surprised that the AIrborne guys don't use Axe FX or Line 6. We all know that Digital is superior to tube 7 days a week and twice on Sunday. Digital is also superior to Tubes 4x every week day and 8x every weekend day. Do these guys read? Do they get Guitar Player For The Practicing Musician? Can they understand more than one "command" function? Glad you got to work on these museum pieces. But you should really steer them towards great gear that makes their shows better, they will sound better and then they will sound more consistent. THAT is your responsibility to them. Tubes are for masturbation. Digital is for real sex. Tubes are for posters. Cardboard tubes. Digital is for REAL musicians who care about the fans getting consistent audio from show to show.

i got my soldano modded just in time! you took on a massive project with these marshalls, excited to see the next videos in the series.

Wow those guys are doing it right! Legends!!

was hoping you would get together with these guys... great tones! they used wizards for a awhile

To my ears they are similar BUT I'm not in the room. so can't hear the resonance. Mercury are however bulletproof in quality and longevity and I've no doubt they will outlast the amp. Sad to see the big M like so many unsold brands (you'd think they would have learnt from CBS etc) who cost cut you invariably kill the brand.

Super informative about the bias regarding the matched pairs. I did not know that!

The 1 to 2 nF anti ice pick cap to ground, do you think it matters if it is located right after the gain input, or rather after the second triode's grid resistor? I've seen in the Ceriatone yeti stuff that it's located after the resistor, right before the grid.

Would love to have a Quad-Cortex capture of this awesome sounding amp! 🤘🎩

That’s the tone!

Very cool!

Great video, very helpful, thanks!

Ya knew it was going to happen... once Jim Marshall was done and gone,...2nd and 3rd generation's do not care about quality,... they care about money,.... their ALWAY'S trying to capitalize on something.. that somebody once did.. that was good,... mine ALL say Milton Keyes,... and the transforer's are Drake's,...and my speaker' say Ipswich England,... the only way to go........

These are great amps but this type of gain just gives me a headache now. I really prefer a more natural plexi sound

ALL ABOUT CORPORATE EARNING$

Cold bias sounds scooped with more raspy highs. A lot of Mesa owners prefer cold bias for that reason. To me, hotter bias just sounds better, more "alive."

FYI if you follow everything shown in this video the amp will not work, the cable mods and work that must happen on the controls board is not included in this video. I had to study the later live stream about the Origin 50 but is confusing because all is not spelled out and its made more complicated by the addition of the diode mods in the amp shown in the video. No novice will be able to complete this Origin 50 mod package! All that said, the ideas presented here are very cool and well thought out and when I did complete my Origin 50 the results were fantastic!!! Thank you for sharing your time Jason to make all these free videos, just think you should warn people about the missing puzzle pieces. cheers

Switch mode power supplies aren't all that bad when properly filtered

Thanks for the great explanations. Why are the filter resistors in the power supply output not included in the plate load resistance for the DC load line? It seems everything is interdependent.
