My Conclusions on the Marshall Studio Vintage SV20 Stack! 

Hands up EVERYONE who would definitely buy a shirt with “Silver Yoo-bilee” on it! Win or without Johann’s image. I think we are on to something!

I wish Johan was my neighbour. I'd love to have those juicy Marshall tones floating through my walls every day.

Probably the best comparison you can find for this amp today. Thank you Johan for all the effort and dedication you always put on your videos! Your channel is a true source of inspiration for me and many others. Cheers from the Swedish east coast!

Have played Marshalls since the late 60s, I am 73 now and use a SV20H head and cabinet with a Rivera rockcrusher in between, a GLORIOUS SOUND. your friend in tone, Norman Mozley

my favourite thing about your videos is that you don't look down on new or cheaper stuff just because it's new and/or cheap - you demonstrate how the amps sound, offer some of your opinion but ultimately I feel like most of the time you try to make clear that most of these pieces of gear can work well in a given musical context. There are soooo many snobby dudes that claim only X year vintage plexis are the real deal and only pre-Rola Greenbacks are any good or whatever. Thanks for your super informative videos. I'm getting a SV20H soon probably, and your videos helped me seal the deal.

Johan, you're the man! Thank you for all the effort and dedication you put into these!

This one is a true gem, so much packed with invaluable information I don't know what to point out first! Everything you need to know when considering the SV20. Have a nice holiday, Johan and thanks a lot for your work!

Really good stuff. Most appreciated. I think you have made it really easy for viewers to draw their own conclusions on which amp is best for them. Very well done.

Excellent video. You are very thorough and detailed, you put a lot of time and effort into these videos. Much appreciated!

A fascinating & expert review of SO MANY Marshall ‘Back Breaker Boxes’, Johan! I really liked the split scenes during your performance segments, that was very imaginative. 👍

Johan, you do a really nice job on these videos and this is a great comparison. Especially grateful that you did the clean tone comparison, thank you!

I love this channel. Thanks for taking the time to make these videos. I really appreciate it.

Fantastic video, thank you Johan! All of your deep-dive analyses and comparisons are great, but these summary videos are so tremendously valuable for organizing the results

awesome to see you giving opinions and describing what you hear , didn't previously do this, thanks

Hello Johan, excellent videos as usual. I must thank you because due to your tests I have been able to reach a conclusion when making the decision of the speakers that I ended up carrying in my cabinet. It was unthinkable for me to agree by my own means to carry out a test of this nature. Greetings from Patagonia Argentina!!

Awesome videos on the SV20. Great work and thanks. Really enjoyed them. You have an impressive collection of toys!

John I really like this new format of you making commentary about your perceptions of playing, very helpful

Bravo Johan!!! Incredible work as always!

Thanks for these great comparisons. My cab is a 2x12 open back cab with two Eminence speakers, a GB128 and a Legend 1258. Great combo, and the amp just sings.

Bravo brother. Another great video. Aside from the little differences in the gain stages of these various amps the core Marshall tone is present all through them all. A few different cabs for each setup would definitely even the playing field even more.

Fantastically, diverse video, as usual. You manage to cover so many of the possibilities of what these amps can do, with both vintage and modern cabs and speakers. While I don't have access to any vintage equipment, it's great to actually hear how the newer amps compare to those classic sounds that we all love. Thanks, Johan for all your work. These are a genuine pleasure to watch.

I really like the '73 JMP . Sounds fantastic. Great job on the vid!

Excellent series of videos on this great Marshall head...thanks Johan you still the best on RU-vid 👍

Thanks, Johan! Love your videos and comparisons. I’ve had a desire for a plexi for some time, but balked because they aren’t very practical. (Same with a Hiwatt DR103) I’ve been using my ‘77 2204 for our band, which is a great amp, but that plexi itch won’t go away! You’re videos and opinion catalyzed me to buy the SV20H with 2x12 stack. Looking forward to running it through its paces! I rehoused the 2204 chassis in a 20” cab, so I’ll be able to neatly use either head with the vertical cab or a 1933 cab. Thanks for all your great videos! I also really enjoyed the 12 combos one. Cheers!

Great job as always! Really like the silver jubilee tone

Thanks Johan. I'll be getting a SV20H in due course, it's just so good.

Great review brother! I bought my SV20 when it first came out. Good to see hear your thoughts because I consider you a primo Marshall connoisseur! Marshall did the gig here man!

Great summary, thanks Johan! A lot of useful info here, together with great tone and guitar playing. Nice to revisit the Comet and Tele guitars, I like how they sound. Looks like you're on vacation. Hope it's nice!

Brilliant comparison! Definitely on my wish-list but clearly needs the right cab. Love that Nordin Comet as well.

Great riffs could listen for hours. Great content cheers

As always great playing and great comparison!

Holaa, primero quiero agradecerte por la dedicacion que le pones a los videos. Segundo, voy a contarte mi experiencia en dos grupos que tengo. El audio es excelente, con un power trio esta justo justo de volumen, y en la otra banda que hay otra guitarra a veces se queda atras. Para shows en lugares chiquitos va barbaro! y el peso de 9kg es impagable. Gran Abrazo desde Argentina!

This is a great review of that mighty little Marshall, thanks Johan Segeborn.👍🙂

Great stuff Johan! Starting at 11:38 & 13:01 really showed off the 2 very well. Both sound fantastic. God bless and rock on 🎸👍😎

Thank you Johan! I agree with where I think your going with this comparison. There's a certain magic that comes from the 50 and 100 watt Marshall power amp section in the mix, especially during live performance. I wish the SV had this magic but I don't here it. Keep up the great work!

Awesome, as always. Thank you Johan!

Man... You really are the best gear channel around ❤️💯👌👍👏👏👏👏👏

Thank you Johan, top quality content and top playing as always. I play my SV20 through a Marshall 2061cx 2x12. Try it if you can, with a Strat I get heavenly clean(ish) tones

Great review! I agree with your conclusions Johan. Thanks brother.

That 1x12" cab with the JBL sounds HUGE. Thanks Johan 👍

I have a Dovetailed Pine cabinet with 2 x JBL G125-8 speakers (200W 102 db). Either the SV20H or the Origin 50 Head sounds glorious with a Gibson 335 or a Yamaha RS502T Revstar with p90's. Thanks for a great informative channel Johan.

Wow! Great comp video!

The SV20 roars in the mix through the 4x12 cab ! 🤩

Nice analysis Johan, thank you! Probably not the first to suggest this to you, but it would be nice to see a thorough comparison of the SV20 to the Origin 20.

Oh yes was waiting for this one! :D

Best Marshall education on youtube! (and other amps too!)

Because the SV20H is so mid heavy, it works just fine with a loud drummer in my opinion. I always keep it dimed, so if you were trying to keep it clean it probably wouldn't work, but for what I use it for its perfect! Especially with a 412. Lately I've been using a Orange 112 with a Celestion 75w Creamback. Love it. Great amp 👌

Great tutorial. I think I actually prefer the sound of the Studio Vintage to the big daddy. I own the Studio Classic and have used it with very loud drummers in a band setting and it was plenty loud with the master not even half way up.

I think the SV20 sounds great overall. When you played the Tele with both with low and higher gain, those were standouts for me. Just “YEAH!!!!”

These go for for 800 pounds in the UK... that's 920 USD. A total no-brainer at that price. Meanwhile in the US they sell for $1,750! That's almost double! Absolutely freakin crazy. It's cheaper to fly out to London and pick one up at Andertons and fly home.

I bought the jcm800 sc20 head and its amazing .it can do clean and also do super lead .i love it.

Another great job. The SV did sound like it would work better for recording. Sounded like a studio album should sound. The Super Lead for that live concert sound. Bit warmer and less cut but much better for the big stages. As for the cabs, the SV212 just needs the years of playing your older cabs have under their belt. I think it would have that certain charm in a few years. As for the Jub and DSL, both good but not as open sounding as the non- master volume amps. I favor the superleads. Cheers.

I really like the sound of this amp. It would be intresting to hear it with a Celestion Fullback speaker. Thanks for the great videos!

Very thankful…. Johan this is a really good comparison video… sv20 is the best Marshall for me…

Great video! For me, the SV20 does everything expected from a Plexi and without having an original Plexi available for comparison it will be mistaken for a vintage amp. The speakers are probably more important than the amp if one wants to go for a different sound with either of the shown/played amps. I like the Celestion Heritage speakers a lot with a Plexi.

Thanks for the amazing video series on this amp and this video was a great summary and very well put together! Have you also tried the combo version? I expect the 1x10" V-Type would be kinda boxy, but then it's also quite portable

A superb vídeo. My conclusion: I'd love to own ANY of this stuff, or even just PLAY it for an hour or so!

Ah the Studio Silver Jubilee sounds so amazing!

I really enjoyed this video

Hi, Johan! Old good Studio Vintage is the best. My favorite combination. Very nice! See you! Siegfried

I run mine through a Suhr PT15 2x12 diagonal cab. So the cab is larger physically. One Greenback one v30. With a 100w fryette powerstation adding a little extra resonance for a beefier bottom end. Sounds great! Wish I could get a Johan review 🤩

Many great sounds!!

Let's go !!!!! Thx this is great Johan 🤟🤟🫡🫡🤟

So, I've finally got one of the SV20Hs. Best amp I've ever played. Traded a Supro Dual-Tone for it. Got it running through a 1960A Lead with the standard G12-75-Ts in and I think I actually prefer that to the other cab I have with V30s in.

Cant wait.👍👍👍👍👍👍

I notice how much you like the JBLs, and I totally agree. They sound so dreamy! Thanks for the tip on how best to get them - 70s Twins, I have duly noted that. :) I have a question regarding that riff at 17:00 on the JBLs. You play that often, and I just love it. I'm pretty sure it's Hendrix - am I right? Which song, I'd love to know.

Johan I think if Marshall were to make a cab that would actually lay that 212v cab on it's side with a straight cab profile so that it would look like a half stack horizontal instead of vertical it would get rid of the boxiness and add bottom end. Love the SV20H!! Love the channel brother!! Cheers!

As a side note, I can tell you that Tommy Folkesson and I discussed the SV-20 a while ago. We both think it’s a good amp. But it doesn’t have the oomph of the 100W Super Lead. But it is a good amp in its own right. The 100W poweramp has so much more muscles and attack and makes the sound bigger. It even sounds bigger compared with its little brother, the 50W.

It is amazing how similar they sound micd for the SV20 to the larger amps. I’m sure in the room there’s a big difference given the wattage and transformers. But through the same cabs and micd I can’t tell much of a difference in the video

The Marshall 1987X is my favorite Marshall I own a hand wired clone. I have the trem model.

Johan, will you do be doing a SC20H series along the lines of your SV20H series? Would be great to see. Thanks, Johan. Wolf

Loved the comparisons between all of them. Can we see you demo some victory amps? If you’re an old school Marshall fan you’d like the Sheriff series.

Well done again!👍 I’m wondering how the SV would sound if it would be 50 Watts instead of 20 …for example through a Fryette Power Station…? Hm…Guess I’ll try it 😉 Cheers my Friend!Wish You all the best!

I wonder how it would sound with a set of original Mullard’s. What country was the SV20 made? Just curious…Cheers Johan!

Hey Johan ... Have you had a chance yet to get your hands on the JTM Studio (ST20H) ? ..From the reviews ive seen its the best of the 4 studio amps...It would be great to get your opinion on it ?

I wonder if you could get some of the fullness back using 15” fullback celestions?

Fantastic comparison...I always thought the SV cab was a little too shallow and small to really thump and Plexi style Marshalls need greenbacks...when you stuffed the cab it sounded like it lost some bottom end

Johan what do you think. For classic type tones Zep Floyd Hendrix do you think the sv20 or a Carr mercury v?

its the bayne of mixing, resonsnce reverb rooms and bass drum, really muds up a mix, getting the cabs stuffed and elements tight is where records sound good, thanks j

Great video. I tried a SV20 in a store a week ago, yes it sounds good but even with a humbucker guitar it was super noisy, is this normal? I then tried a SC20 and that was much more manageable noise wise, I thought sounded better than the SV. I haven't had a opportunity to try the 2525 yet, I think from your reviews this is the choice for me but I am hoping to check it's noise level first because if it's like the SV noise wise, I'll pass and stick to my JVM and DSL40 for Marshall sounds. Regards.

I contend that the V-type speakers are specifically made to be played at bedroom/living room volumes/venues. Never heard them sound good playing with a band. I use my SV20h with a Mojotone Bassman 2x12 of Celestion Gold/G12H30 Anniv. So sick!

Would love some videos of the hand wired ac30 amps in the future

Is it like wine? the vintage amps, because of their long time use sound wiser amd fuller? My Fender Twin RI sounds warmer and fuller after 2 years…thank you so much for the wisdom!👏🏻👏🏻👏🏻👋🏼🧿

The mini Marshall’s have smaller transformers so they sound thinner and less ballsy. Not so important for cleans but a different story for distortion. I would always use H magnets with the 20W amps to compensate for smaller iron.

Is the fuller bottom on the big amp, down to the bigger transformer mostly?

The SV20 sounds like someone needs to go through and tweak the various capacitors. It had less high-end and less lows, and sometimes had an obnoxious honk. It would be interesting to go through the schematics vs a plexi to try to find out what changes are leading to the differences in tone.

Do a video of this amp running through four 4x12s and how it compares in tone and volume to the 2x12

99 times out of 100,almost no one could tell (or care) the difference,the SV20 looks and sounds amazing and no technical issues compared to amps that are 50+ years old.

I played a sv20h with a sv112 cab. I would like to your opinion about the sv112 cab. Thanks! Great demo!

The sv20 sounds best when the channels are jumped. Just has more character. The ‘71 Super Lead sounds warmer

Yes. Thank you Johan.

Does the SV20 have more gain than the 1987x?

I think the guitar here shines. What model and pickups is it? Thanks johan

Hi! How does it compare to the vintage modern? Thank you!

What has more distortion the sv20 or bluesbreaker ?

Suddenly now for the first time I like how the Jubilee sounds. So I guess I now need to buy that as well, on top of the 6 Marshalls I already have?

Just got the Marshall Mini Silver Jubilee 20W ...It has channel switching but the Studio Vintage 20W does not. Also got the Marshall JCM-1H 1 Watt 50th Anniversary Amp....tiny and super cute.

Let's go !!!!

GREAT VIDEO! THANK YOU VERY MUCH. FOR MY PROJECT I WOULD RECORD WITH MY ORIGINAL '74MARSHALL LEAD & BASS JMP50 MODEL NO.1964 AND MY '93MARSHALL SLP1959 MIXED TOGETHER IN VARIOUS COMBINATIONS WITH VARIOUS SPEAKERS AND CABS(1X15, 2X12, 4X12, ETC) OR, WITH ONLY THE 74 AND A 1X15 CAB IF IT WAS N'T POSSIBLE TO BRING ANYTHING ELSE. FOR OTHER "BAND" PROJECTS I WOULD NOT USE BOTH, FOR CONVENIENCE REASONS ONLY. EITHER ONE WOULD BE OK. BUT IN MIKED LIVE OR STUDIO SITUATIONS ON OTHER PROJECTS, THEN THE STUDIO VINTAGE WOULD BE PERFECT FOR ANYTHING AS LONG AS THE SPEAKERS WERE TO MY LIKING. TONEWISE THE ORIGINAL HEADS ARE WAY ABOVE ANYTHING. IT WOULD BE A LIE TO SAY I COULD LIVE WITHOUT ONE. BUT FOR WORKING MUSICIANS IT IS OBVIOUS THAT THE SLP AND THE SV20 PLEXIS ARE ALRIGHT. CONCLUSION: THE SPEAKERS ARE THE KEY TO MAKE THE NEWER MARSHALL HEADS FIT TO MY (SPOILED BY OLD HEAD SOUND) EARS.

I have yet to see you utilize the clipping feature on the mini jubilee, clean channel with clipping engaged is another classic Marshall tone not to be ignored! I have both the 2525h and SV20 with a 2061 cab, probably a better 2x12 option than the current 2x12’s
