Marshall Modified Amps & NEW JCM 900 Studio!! NAMM 2025

[@adammcgarry2270]

The modified 1959 looks sick

[@12breacher82]

Man as soon as I heard these were coming out I was peaked. Been waiting for Marshall to do their own mods and hotrod amps for years. I have several stock and modded versions and they backbone so much of rock and metal. Definitely like all 3, but the JCM 900 and 800 are awesome sounding.

[@RiffLair]

A whole 1 hr of this is what my soul needed! Thank you!! 🙏

[@freezeframeplease]

the jcm 900 was my first tube amp back in the day., a 2x12 jcm 900 combo. sounded amazing with high output pickups and low tunings. i might buy this just for the nostalgia feeling

[@tomshoemaker662]

Woohoo!! 🙌🏻 🔥 C’mon Marshall get these things to the US!!

[@jessejuno5317]

That 1959 is looking good…my next amp..

[@jroobz]

The modified 800 is the one 😮❤

[@adamwatson6916]

Good lord how many times do we need to get the history lesson about 60s and 70s Marshalls . Every video about a Marshall Product has the history lesson .

[@bojangles4704]

Marshall finally doing something this is awesome , JVM studio all but guaranteed at some point, I've been waiting so long

[@TaylorBellemare]

I hope so! The JVM has always been my favorite amp. I want one of those 1 watt heads but they are just too pricey used. A studio version would be awesome.

[@bojangles4704]

@@TaylorBellemare I own the JVM 50th anniversary 1 watt and absolutely adore the amp , that's the reason I want the JVM Studio! Our time is coming brother

[@birdsfabulous]

Would love a JVM studio...matter of fact from here on out all marshalls should get a studio variant mandatory!! Hahahhahaha.. i have the studio vintage since i love the plexi tone but would love to add a silver jubilee next, maybe 800 after. A JVM studio would go top of list instead though..very curious about that amp..seems to do almost everything well

[@bojangles4704]

@ the studio vintage is a sick amp! I think you would love the JVM in your collection, the whole studio series is so collectable hahah

[@michaelgallegos8811]

Damn the 800 is a beast oh my lord😂❤

[@kleinekoosjer]

This new modded jcm 800 sounds really good by the way.. I only wished they had put those gain stages in a foot switch, that would have made it great.

[@axeslinger]

WOAH NEW MARSHALL AND BROUGHT TO US BY NON OTHER THAN ANDERTONS!!! LETS GO! 🎉

[@darellville]

Yes!! Bought time!!

[@AbitLippy]

Sounds great but would like to hear a Les Paul through it as well

[@johnsmith-ug5tp]

I thought the same.

[@Mr.Goldbar]

Eat Em & Smile has such an insane tone! And it was all done with modded Plexis! both a Jose and a Lee Jackson :)

[@wilrasmussen5005]

I freaking called it!!!!!!! Jcm 900 studio!?!

[@satchrules101]

Marshall The best and undisputed champion of the rock and roll 🎸 world. The plexi destroys any amp builder that try’s to copy Marshall ! Never underestimate Marshall the spirit is unstoppable!

[@virzito]

Finally, it was time for a revamp of the line. Good job! Anyway , on the 1959, for me, it was better to keep all 4 input and place the mastervolume elsewere. And also put a send and return

[@georgetwydell6166]

I love the bright cap… but I’m also a Les Paul player. Naturally a darker sounding guitar than the Strat. The Les Pauls darker character complements it

[@didamnesia3575]

Bright caps should always have a switch to turn it on or off. Imo. Its 2025

[@georgetwydell6166]

@ yeah man I agree, nothing I said implied that I didn’t think having the option was a good idea. I think it’s a great idea and if on the occasion I’m using a Strat or Tele, it would be off! I’m just saying my personal preference for when using a Les Paul which is nearly always is I actually do like it. :)

[@Spidouz]

I would love for Marshall to add the 1974X to the Studio Head series…

[@antilaw9911]

Have these both sitting on top of my 1960 Vintage 4x12 I would just sit and stare at them all night. So Glorious looking Sick! 👍

[@chrisquinn9104]

Cool Marshall has just released a Peavey VTM 40th anniversary with fewer features.

[@JimThompson-i3u]

Totally missed opportunity releasing a modded Marshall without swapping out the 10s for 11s.

[@djHypnotik3dc]

They made 10 11

[@didamnesia3575]

Buy a Friedman, they go to 11

[@lmn0potts]

I never noticed that, lol. I know Soldanos go to 11.​@@didamnesia3575

[@beaumas]

Oh hot dam! They sound good.

[@joserdiazalmodovar1898]

Great News by Marshall 🤘 The Mod Plexi and the Mod 800 Very Nice would be cool to get some of the mods on a footswich. The 900 Series blew my mind with Real Spring Reverb. 🤘🎸❤️

[@neuntoter9345]

That 800 is one of the best Marshall tones I’ve ever heard on KZbin.

[@joejitsumusic]

loving that 800

[@PrimalScream91]

Mick Mars' Jose modded 1959 is the tone of my dreams

[@lostinpa-dadenduro7555]

I like the 900

[@tobiasryan8378]

Awesome to see Marshall finally bringing mods to the market. That 800 sounds fantastic. Please keep up with the 100 watt tube amps!

[@warrenvollaro2529]

Love the guys at andertons-

[@shanevain3759]

Why didn't Marshall create some of those famous modded sounds that other brands reproduced?.. Well, a friend of mine actually asked Jim Marshall that point blank once, and his response was, "I think they're quite fine the way they are"...

[@PurposefulPorpoise]

The "size"/"sound" thing is voltage. Smaller amps have less voltage running through them. Bigger amps have more voltage from the transformers. Voltage = TONE

[@YMESYDT]

I appreciate what they’re going for but I still think the Malmsteen was the modded Plexi everyone wants, bring that one back! Attenuator, reverb, mild boost, end of discussion

[@geoffh8077]

And the extras were all on the back so it still looked classic

[@kleinekoosjer]

I used to run my jcm 800 high with a ts.. but got in a lot of fights with the lovely sound guys. 😅 I had to always turn it down to a point where I lost my sound. So I went for the Billy Corgan way and run it in the low; master all the way up and pre to taste (not much, just the volume you need). This way it got the nicest clean tones (awesome low end, which I like) and it functions as a great pedal platform. It takes muffs and distortions very well and I can keep my sound at lower volumes on stage perfectly. Still prefer it loud, but at least one guy in the room is happy 😅

[@rob.carrillo]

As the sound guy, trust me when I say we're just trying to get the best sound possible for EVERYONE involved 😅

[@kleinekoosjer]

@ Ha, I know of course 😇 and wisdom comes with the years. And although a cranked up jcm 800 is what most players want from it, I got familiarized with it running low. It’s still very very good and heavy. It keeps the crowd in the room as well, yes 😂

[@fallenshallrise]

I love the idea overall but would love to see a MKII with more frequency shift mods on the pre-amp and some quality of life mods on the back panel like 50w/100w modes and an effects loop, maybe a resonance control or a gate.

[@runabout76]

Channel switching became a thing for Marshalls in 1981 with the 2205/2210 models and their solid state stablemates. When I was at the factory shortly after the JCM900 reissue was released I asked why the 4100 and not the 2100 Dual Master instead (Mk III or Mk IV), was told this is what the DEALERS asked for. Every guitar player that talked about them all asked the same thing, Why the buzzy/weak one and not the real Beast of the 900 line... Oh well. Nothing for me to buy this year still. I'll stick with my JMP-1 Preamp to get all these tones.

[@ΓιάννηςΓουμαράς]

I object! 😂 I ordered the jcm800 classic a couple days ago, I was between this and the big head but thought the studio classic is enough watts already... But if i knew about the new modded one I would get this instead 😂

[@tonedover]

Get a legendary tones hot mod evo2 and save $800

[@marvelharris9540]

So is that a "post phase master" or "pre phase master" on the 1959?

[@DamageToleranceClothing]

That JCM800!

[@MAG-li5jo]

Looking forward to NAMM tomorrow.

[@greygardens81]

Influencers: big tube amps are dead Marshall: Hold my beer

[@johnsmith-ug5tp]

Influencers = sally boy YT geeks. haha

[@12breacher82]

Note on the 900: using a gain, eq, and/or OD through Channel A is quintessential 90’s death metal. Morbid Angel specifically uses a dimed CH A with a Rat, EQ, and several fx pedals run up front, with specific sludgy amp EQ settings. You can’t achieve those greasy tones on much else, and definitely not from the CH B circuit. It is a hidden gem for anyone unaware of it’s pedal platform capacity. Adding other FX and a gate to the loop and you’ve got quite an awesome rig.

[@PureRedRage]

Friedman is coming out with the Jose amp and I’m much more interested in that than the modded Marshall that’s like 45 years late.

[@vincecoste6365]

Hmm nice amp heads but not going to buy any more expensive Marshall amps already have two , Marshall DSL 100 HR , and older JCM 800 with Mr Scary mod

[@someoneelse9271]

The cab. What’s it loaded with? I missed if they said. Can’t quite read the label either

[@fuzzymuppet1990]

V30s beleive it or not

[@johnsmith-ug5tp]

V 30's

[@someoneelse9271]

@ 1960 vintage cab? Cool thanks 🙏

[@tonedover]

Im so so underwhelmed with the 100w offerings at the leaked price point. Unacceptable.

[@Doombot2point0]

"anything slightly under 100db in here is pleasantly loud" Lee, which brand of hearing aids would you like?

[@johnsmith-ug5tp]

I blew out my left ear drum before i was 20 after i bought a marshall 100 watt stack. Cranked in the basement and played it for hours everyday. Dumb ass! I have constant ringing, buzzing, hissing and lost all my high tone frequencies. My right ear, just a little hissing and no hearing loss. I always wear ear protection around any loud music or noise. I learned the hard way. The first two years of the ringing and hissing I wanted to jam a pen in my ear and make it stop. People have actually offed themselves because of it.

[@ToddTheJoker]

So weird cuz cuz just late last year I was talking to someone about how it would be cool if Marshall themselves would come out with of their classically modded amplifiers instead of just having to chose from makes like Friedman etc..way to go Marshall! long time in coming but glad u are doing it

[@fuzzymuppet1990]

I know it's kind of unpopular opinion. I wish they made the studio series where they make the dsl stuff. I would love a sv20 or sc20 for about $550-600 bucks. (US dollars). Or maybe do like freidman did with their IR line of pedals. I know marshall just released new pedals. But we need the tubes.

[@BaronsDuju]

Wait, they put a switch on for an internal clipping boost pedal instead of switching another preamp tube on and off? I mean.. we all already have our favourite boost pedals in our collections. I’m assuming people would have preferred a valve instead? And no effects loop?

[@wieliewiel2630]

Nice!

[@dethstormpx4]

Should have modded the 30th as well.

[@flyingrhoads]

Will the Jmp and 800 be limited?

[@ianbenson7804]

Finally. Now I can possibly have a true Super Lead I can use in the bedroom. Remove 2 power valves - Master Volume - into Torpedo - IR Box - flat amp - into 4x12. Nice.

[@IamtheFerryMan]

If you're running it into an IR box, why remove the tubes? I get that would be to reduce the wattage, but it makes no sense when the IR box usually handles 100w. Just crank the danged thing up 😊

[@ianbenson7804]

@@IamtheFerryMan Really because at bedroom level, a highly cranked amp of more than say 20-30 watts still sounds like garbage through the Torpedo - it just compresses and frats out too much. 50 watts from the '59 *with* the master volume should definitely be in decent tolerance level for the Torpedo.

[@ianbenson7804]

@@IamtheFerryMan Also, the Torpedo is just the attenuation, I'm then running line out to a separate IR box and then into a flat response amp and then to the cab.

[@IamtheFerryMan]

I had a Torpedo Captor X for a few years. Are you just using a Captor or something else from them? I never had that experience. I used it with a JTM45 my friend built, a Mesa Mark V 35, a Koch Powertone II (120 watts, so didn't dime it), and multiple 40 watt Fender combos. Weird you're getting garbage tones out of it. Either way, if you end up going that route, it'll probably sound badass 🤘

[@chopperdeath]

Nice.

[@pauljackson2938]

3k. Will wait to hear daves Jose modded friedman.

[@tonedover]

$3599 usd was the leaked price on sweetwater. Id EASILY pick a channel switching Friedman or Bogner at that price point

[@litos_mendes]

Soooo americans now you now what we suffer with mesa boogie amps 😂

[@mswishe4]

These amps have been around for decades. I’m pretty sure we all know the history of these by now. Explain the mods and let us hear how they sound! Even when you played, you barely played! Re-do with more riffage please.

[@bradleywood1499]

Les Pauls everywhere and decides to use a Strat to demo these modded Marshalls. Okay then..

I still have my 1992 EL34 loaded JCM 900 2501 single channel 1x12 combo, that thing is a built like a tank (only had to replace the valves 10 years ago) and it sounds huge, also takes pedals great! I will never get rid of that amp!

[@nunyabusiness6691]

Is the dude on the right having trouble breathing?

[@StandupRoss]

The pumpkins around Siamese Dreams used the low inputs of there JCM 800s. They cranked the master and used the pre amp to get the sweet spot and used a big muff for the tone. Also Steve, swallow your spit. Your slurping before chat was so annoying.

[@buckbumble]

Shame those great 20w amps really shot up in price. The JCM800 studio was around £700. Now it’s £1200. I’ll leave it

[@willgoodey1892]

Where are you looking bud? On the andertons website they're still under £800

[@buckbumble]

@ was referring to the new studio demonstrated here

[@willgoodey1892]

Ah I see i hadn't reached that far yet. I will say I have to agree, double the price for an added reverb seems ridiculous

[@johnsmith-ug5tp]

[@brightfalls6788]

I wonder how many years we’ll have to wait for a modified version of the Studio Vintage that doesn’t cost $4,000… Or even better just the basic master volume JMP reissue we’ve all been wanting forever.

[@StavK]

If you’re in the US buy a Friedman, if you’re in the UK get one of these. Is this a safe assumption these days given pricing?

[@stoneysdead689]

Not in the mood for a sales pitch, so I'll grant you I'm probably being a bit harsh - but really? A 900 with no fx loop and no on-board reverb or delay- how would you use a reverb or delay with it? Unless you're getting your drive from a pedal, your reverb and delay are now before your drive- which sounds like crap generally speaking- that's why they added reverb afterwards for this demo. But you can't do that playing live so- what's this for- studio use? Guys who prefer playing dry? Or are we just so convinced now everyone will be running it into something like the Ox Box that has reverb and delay built into it that we're no longer going to bother with fx loops? Ah whatever, I couldn't afford it even if it was built like I wanted so- I guess I'm not the demo they're aiming at anyway. Carry on with your regularly scheduled programming...

[@19581998]

You guys really don’t know your customers. What a catastrophe of a demo. Find a Les Paul and crank it and stop talking.

[@timnotbrianmay]

I had a 1959 double stack in 1977... I was going for the Alvin Lee at Woodstock sound! Plugging straight in to the first input, I quickly found out the thin piercing sound produced, and remembered seeing pictures of them being jumped! That was the fixer! But I still had to turn it up to seven or seven and a half, or beyond, to get a really good sound! Still, it was UNPLEASANTLY LOUD!!! I ended up using a boss overdrive, but that never got me where it needed to be come up but pretty close! I tried lots of ways to pump up the thickness and gain, but never ever did anything work quite correctly! I ended up getting in the Altair power attenuator, because they were the only thing available back then!!! Once the original tubes went " ick! ", it never quite sounded the same! But as far as a 4x12 being the BEST guitar sound EVER, I do MUCH PREFER The 212 AC30!!!!!!!!!!! STILL PAINFULLY LOUD!!! 🙀😾😿😸😸😸 I think that when you turn it down, no matter HOW You do that, you lose attack and articulation, including the THUMP, That leads to the "loss of excitement"That you described!

[@RezaMatix]

this whole thing was a bunch of talking what the hell is going on here? Are you trying to sell the amp or explain everything ? we don't need the explanation! plug-in put it on high gain chug. Let us hear that it can do. Heavy rock metal. The reason why it's modded, etc.. We just need to play through a video without any talking show us how aggressive the Amp gets by itself without any Pedals. There's no point in buying a modded amp if you have to use Pedals.

[@rhabs2895]

Agreed. Did Marshall use a label maker? 😀

[@geoffh8077]

I think they’re trying to go for the look of old Marshalls that were modded. They tended to look that way as the switches and extra knobs are added to an existing chassis. If you wanted them to redo the whole look for the new features they did do that, when they made every new amp after the old originals.
