I had a JCM900 in the early 2000’s that my dad bought for me. I didn’t like it that much because I really wanted to have a 5150, but nowadays, I regret getting rid of that thing.

[@LonelyRocker]

Ahhh the one that got away...it's a common story :)

[@NoCoverCharge]

Ha I traded my 5150 in early 90’s for a 900 … I loved that 900

[@BassRocket]

That late 90s early 00s 5150 is a beast. I played with a guy in a band that had a 5150 and that thing was a beast.

[@lastgreathand-drawnproduct3843]

I have a similar lament, and it wasn't even my only JCM 900 at the time. I had a 4100 Dual Reverb and a 2500 MkIII, both from 1990, and I was on hard times in 2006. I had to part with one, and I let my ears do the deciding. The MkIII and I are still riding together to this day, but that 4100 was still something else 😕

[@rjo8500]

I’m older so my first Marshalls didn’t have master volumes. I was thrilled when the 800 series was released. I owned a slew of them, preferring the 2204. The 2203”s were not consistent. Some were overly bright and clean. Could be tubes, bias but I know Marshall was making changes. The 2204’s were unchanged and more consistent. Unfortunately I didn’t keep any of them. When I tried to go back prices were insane so I went the 900 route. I had several 4500’s and also the covenant single channel 2100. They’re not bad but completely different than the 800’s. The 800’s just sounded massive, bigger lows with great harmonic content. The 900’s were a bit muddy turned up. Under the fingers they feel very different. I think that bothered me the most. Take an 800 over a 900 every time.

[@LonelyRocker]

You are right, they are very different amps. And it's common if you came up on the 800 to not like the 900 as much. however I encounter just as many fns (almost) of the 900. That's what I love about amps!!

[@rjo8500]

@@LonelyRocker Agree. I do like the JCM 2000 DSL 50 watt heads. Those are a closer to my ears to an 800. I played them side by side once and was able to dial in a crunch tone remarkably close. Controls were set vastly different. Dialed in the 800 first.

[@Gondyr_Nocheinsson]

This pretty much is what I always felt, too. 800s feel different, very immediate attack and response, and a sound you can actually feel moving in the air. Playing 900s always felt like they would be in the room next door. In the end, I discovered the 1987 50 Watt Plexi to be my favourite Marshall. That thing just slays.

[@LonelyRocker]

Ok Plexi. Unfair comparison 😂

[@TwistedRiffster]

Are you Mick Mars?

[@panikpas]

The 4500 gain stage is mostly based on Op-amp and diodes clipping. The Tone stack is completely different also. It think, as a lot of people was inputing a boost pedal in the 800, that Marshall wanted to reproduce that kind of sound. In the 4500, only one triode is use to create the overdrive, the rest is gain staging between Op-amp. The preamp is more close to the first Valve-State series then to a 800.

[@LonelyRocker]

Thank you for your insight!

[@K707OR30]

This is correct. I don’t understand the fixation and whining about the diode clipping in the 4100/4500s when really the preamp gain staging and tone stacks are almost nothing like a 2203/2204 circuit. The diode clipping is probably 10-15% of the overall tonal profile, maybe less. It isn’t the deciding factor in the different sounds between the two circuits, not by a long shot. If more people understood the circuits of these amps they’d realize it’s honestly kind of silly to compare them because they’re so dissimilar. Either way both amps sound awesome, just very different ways of getting there in the preamp section.

[@guitarexpert2245]

Your correct. I bought one 3 weeks ago from Guitar Center a mint 93 el34's to test out of curiousity. Was going to replace my 2000 with the 900 but have concluded the 900 is better than expected but the 2000 just has... more. Much more punch, so much more low end, sounds more organic, clean channel is richer. So i'm sadly returning the 900 tomorrow can't afford to keep both. If i could afford to I would keep it. But it's definitly a different flavor of a Marshall for sure. I do however have an SL-X which I'll keep forever.

I currently have and am a 800 lover, that being said I think the 900 4100/4500 is a great amp in its own right. I had a 4100 for a while and found the bottom to be thin at times. A trick for that is to use the fx loop or a jumper cable and set the mix to around 11:00. I don’t play much cleans but loved the clean channel as well

[@LonelyRocker]

Thanks for the tips! I find it's a great recording amp. Since I go direct and I had it modded it's become a real workhorse in my studio...

[@joeMW284]

The fx loop trick is real. It does thicken it up in a very nice way. Seems to add low mids.

[@batman44vt]

I play Hard Rock/Heavy Metal/Classic Rock. I've had both amps. They are both good amps. I have to side with the 900. I like having two channels and more gain. With the 800 I had to have an overdrive pedal in front of it. If I didn't it didn't have enough gain period. The 900 has more then enough gain and you have two channels to go back and forth on the fly. The reverb on the 900 is good to have as well. I just barely have that on with a little delay for effects. I still have that amp to this day. I bought it back in 1992.

[@LonelyRocker]

Nice to hear some positivity about the 900. Some 800 fans feel the need to bash it. Which is generally related to the type of music they play. Thanks for sharing!

[@christophergrimaldi8757]

[@robthebear2850]

My first "real" tube amp was a JCM 900 (100w dual reverb). I had grown up around friends during the 800 hey-dey, but knew from day 1 that this was a different amp. Sure the master volume plays into it, but I have never plugged into an 800 that sounded remotely similar to the 900. The 900 always struggled to sound like anything more than a Marshall wannabe. I never thought that I would sell my first real Marshall, but ultimately realized that it wasn't the real deal and moved on. I have a Splawn showing up next week, so hopefully that fits the itch.

[@LonelyRocker]

It’s true. If you want an 800 a 900 won’t cut it. Vice versa I guess. Let me know how the new amp works out!

[@reverendg5937]

I have a Python Covered Quick Rod & a Competition. Love the Competition just a little more.😉

[@bryanp8010]

There’s no debate. 900 is cheaper and honestly superior. The 900 has channel selection and that’s huge. I put el34 tubes in my 900 and it rocks just as much as any 800. At half the price and more options the 900 wins. The right tubes in the 900 wins 😛. Slightly less bottom end but it’s barely noticeable.

[@LonelyRocker]

Love when 900 fans step up! This debate rages on! Thanks for you input 😎👍🏼🎸

[@guitarexpert2245]

Dude it sounds nothing like an 800. I have a 900 DR el34's stock,. I can't sound like an 800 the entire pre-amp is op-amps get's it gain from the op-amps which is Solid State then on top of that is the diodes. 800 pre amp pure tube. 900 has no low end unless put EQ in loop. Doesn't have the punch of an 800 and it not as bright of an amp. It's a darker tone. Still sounds great but alike to an 800? NO way.

The tones sound killer in this video! I have a modded JCM900 100 watt Dual Reverb. I had it modded when it was time to change the capacitors in it. I didn't like the change of tone and the fizziness when I switched between the A and the B channel. I had my buddy do a mod to tame the treble and I wanted the B channel to sound like the A channel but with a lot of gain. He succeeded with the mod and I love the fullness of the B channel with all of the gain.

[@LonelyRocker]

Thanks! Love the concept of your mod. I’m sure it sounds awesome!

[@takat1113]

The 900 is my favorite and i don't really have a good reason. The Marshall with the most options in tone imo is the JVM. Great head.

[@LonelyRocker]

You don’t need a reason! JVM is on my “to acquire” list 😎🤘🏽🎸

[@BobCorey]

I had the 900 and sold it, it really felt like the drive was coming from a pedal, and from what you say I wasn't so wrong...Sold it and went back to the JCM 2000 DSL 50 that the drive channel sounds more pure and full to the ear for me...

[@K707OR30]

The consistency problem is probably tone stack value screw ups at the factory. Marshall is pretty notorious for the schematic saying one thing and the value of a component being something else. Not always a big deal. But if you have a LPF or HPF and the value of the capacitor is supposed to be .1uF and someone puts in a .01uf or a 1uf, it completely changes the crossover frequency value of the filter and it’s gonna sound different from all the other ones they did “right.”

[@weedshoes5089]

That's a long way to say poor qc.

[@middle_pickup]

Doesn't the silver jubilee amp have the diode clipping too? People love those, but not the 900? Also, is the 900 a good pedal platform kind of amp?

[@LonelyRocker]

You’re right. Many Marshall models have diode clipping. The 900 just gets a bad wrap. The 900 is an amazing pedal platform. Especially through the clean channel. That’s where I dial most of my tones.

[@middle_pickup]

@@LonelyRocker Good to know. Thanks.

[@guitarexpert2245]

In addition to the diode clippings the 900 pre-amp is all Op-amps. Meaning is a big solid state pre-amp. Unlike other Marshall's are pure tube pre-amps. The Jub is pure tube with Diodes. So it's different hence why they are loved. the 900 DR gets a bad rap for a reason. But i don't think in this day and age it matters like it did in the 90's.

[@middle_pickup]

Good Day. Excellent comparison of the two amps with great details and personal comments. About 6 years ago, I sold a JCM 900 Combo amp 12x2, 50/100 watt that I bought new in 1994. I wish that I hadn't sold it. Hard to find new amps that are actually made in the UK any more. Thanks & Best Regards.

[@LonelyRocker]

Thanks so much! Sorry that one got away. But hunt around. 900s are pretty reasonable on the used market. Maybe you’ll find a gem. Good luck!

[@goobiecaro8135]

I have both types: 4104 and an SLX. Very similar. The 6 knob stock 4104 (2204 in combo form) sounds louder and more open than the 900. The SLX ( 8 knob head thru same speakers in combo) has more overdrive on tap but sounds more compressed and not as bright or loud. Both were spec'd with a meter at same db. Your ears will perceive the open brighter amp as louder. Funny how so many say they prefer the 800's and then throw an overdrive or distortion pedal in the front which mimics the 900. At the end of the day, whatever makes you want to play and can deliver your tone is all that matters.

[@LonelyRocker]

Totally agreed. And thanks for your insight!

[@mikehart8353]

I personally like the gain of the 900 myself, but I think as always it breaks down to what the user is looking for. In my experience with both, an 800 has so much push from the speakers that it will blow your socks off on volume 2. Like Marty in Back To The Future. It is my understanding that this is the debate between the 800 and anything made afterwards. As though the marshalls of the 80's and earlier were made before everyone was getting mic'd on stage. They didn’t need as much of a push once everyone was getting mic'd at their gigs. An 800 100w pushes much more than the 900 100w. I hope I explained myself well enough. Hahaha! I'd buy the 900 over an 800 any day because it fits my style of music better. But, I'm not here to debate. Just my preference and experience. As i said, it depends on what the users preference is. Thank you all and have a great day

[@riffsnoleads]

not sure if anyone mentioned it here but a good work around with the JCM900 instead of modding is to CRANK the gain on the clean channel to max and then use that as your crunch channel. To me it sounds more like a "classic" Marshall that way and if I am not mistaken it bypasses the diodes since they are only in the channel two signal path. I'm a volume knob guitar guy, so single channels are my preference at the end of the day really though.

[@LonelyRocker]

You are 100% right. I think I mentioned I use the clean channel more. And you are right again. The clipping diode circuit is only in channel B. But that clean channel is killer. Especially driving it with a boost. Very underrated amp....

[@burningjoe]

Yet another reason why they can be so different, that JCM 900 4500 most likely has 6L6/5881's right? And the JCM 800 2203 has El34's. I have a JCM 900 4100 built in 1992 so it still has the EL34's and sounds light years different than the same amps built a year later with the 6L6/5881 tubes. I've had it modded but did not bypass the diode "trickery" in the front end., and now it sounds like a JCM 2555 (Jubilee) which also has that same Diode trickery in the front end, but doesn't get the hate the 900's got. But, I love my 900 after the mods (be Jens Kruse)

[@LonelyRocker]

Nice! I'm not sure what mine has. I'll have to crack it open again. Though it was re-tubed a couple of times so who knoes!

Tubes are not EQs, they just amplifies the signal. Some are louder, some have more gain or tend to clip sooner but they are not supposed to change the tone and so they do not! It's the same BS with "tone wood" on solid body electric guitars. Some even believes that paint changes tone. 🤦‍♂

It's about preference for me. I don't think 900 sounds like a 800 with or without clipping diodes. I just like the JCM800 /2204/ better, and I like the 900 but not as much, same goes for other series as DSL, they are not bad it's just not my tone.

You nailed it. It’s a taste thing. They ate different amps that cater to different things.

It gets even murkier in the realm of heavy metal type tonea. Style acounts for some much, especially with all the boost pedals used. People on forums never seem to take this into account.

[@LonelyRocker]

VERY VERY good point....so true!

[@kurtbader9711]

Yes, you set up a tone for your own ears, but everyone hears it differently. I think a great component of style is the harmonic content created as well as pickup choice etc. You have to have a decent guitar and amp, but after that it's all in your hands.

[@temujenbarca1284]

I used to own an 800 (albeit a Studio series...) , and I really fell in love with it. Vastly more versatile than some would claim it is, for one thing. As for the 900, never played one, but I've been tempted many times to just buy one used, when it would come up. Frankly, if I was more of a Strat or Tele player, I would go straight for a 900, I feel that it has just a little more "body" in the spectrum where single coils often need a little help... Great vid, I really like the way you go about things..!

Thank you so much!! Really appreciate your thoughts. You likely can still find good deals on the 900s. I think they are great amps. I've played my Suhr T through it and it sounds awesome...good luck!!

@@LonelyRocker The 900s are used by some of my favorite guitar players, and to be honest, an 800 on its own doesn't achieve that heavy heavy distortion. I always boost mine, even in the high gain input.

I like the sound of both. Combining them in a track sounded amazing. I like the 800 crunch to bring clarity to the overall sound and the 900 to bring thickness to the tracks. If I could manage it, I'd own 1 of each. In a 2 guitar band it would really help the guitarists stand out but stay similar enough to have a cohesive sound.

I think if you want to compare the 900 to the 800 you should do it with a 2205 or 2210. The 2203/4 are a completly different concept of amp that should be treated as such. I mean, you wouldn't compare a 1988 Mustang GT to a 2005 Ford GT , would you?

The Slx will always have the diode present even when turned to 0. The only 900 model that you can take the diode style out (besides modding it out) is the JCM900 2100. Rare and hard to find. 2100 is very close to the 2203.

[@Albee213]

I have a 1982 JCM 800 MKII 2304 50 watt. With a booster it sounds awesome. The problem I have is its useless as a "home" amp. 1 or lower it sounds terrible. 1 or higher and its just too damn loud. I use a JCM 900 MKIII 2500 and its a more user friendly amp. Sounds good at any volume and has an effects loop. I also have a JCM 2000 TSL. While all three amps in my opinion are fantastic when used properly. The 800 sounds awesome with the least amount of tweaking. Guitar, booster and head turned loud. Thunderous roar that just sounds natural with no grainy hiss. The 900 sounds the most unique to me compared to the 800 or 2000. The 2000 can sound a lot like the 800 however no matter what I do the tubes run at nuclear temperatures. I have replaced the mainboard, biased serval times and used a few different tube sets, but seriously its SUPER HOT. The other amps can run four hours on end and just get very warm but nothing concerning. The 2000 makes me nervous.

Beautiful guitar and sweet playing. I never knew about Diode Clipping till I saw people arguing online. I had a JCM800 4211 combo a looong time ago, I mainly used the Clean channel with pedals.I since found out that it had an extra tube gain- stage after the diode clipping too.I loved it anyway.'Split Channel' that I never used fully. All I know is that I loved the amp. I have a Silver Jubilee combo from 1987 which I totally love but also gets berated for the diode clipping. Although I understand people..and discerning taste is good but there are many ways to write a song and record it.Ya know that !

Thanks so much!!! Diode clipping gets a bad rap. Mainly from people that don’t understand it. Amp manufacturers are always tweaking their circuits to refine the tones of their amps.

[@jacksmith4460]

When it comes to Indie Rock and Cali/Skate Punk actually think the 900(4100) is the best Amp for the job, its perfect for such genres with Hi -ish gain but stopping before you get to metal. I think the 900 is a good amp and will cover most bases in Rock very well, for Metal though It never sounded right to me. The 800 does, but usually because you need extra gain from a pedal to get the Gain needed for Metal, so some of its benefits are how well it takes pedals. For metal it almost forces you to add something, meaning its promoting at least some uniqueness in tone combinations. The 900 can do this but the Diodes make it sound odd with drive pedals, which are pretty essential in Metal regardless if your amp has enough gain (OD's are used with Hi gain metal amps to change response , not always to add gain) I have an 800 myself (as well as a Peavey 5150 and a Jet City JCA50) and I was in band with another guitarist who used a 900 (I was using a my 5150 ) , it was a Hardcore/Punk/Metal band and the 5150 and the 900 fitted perfectly tonally (although my 5150 blew up after a few shows and I had to do the rest f the Tour with a VS100 which held up well)

[@LonelyRocker]

[@joeMW284]

The A channel of the 41/4500 rules. Might be my favorite Marshall sound. It's like a more refined 800. Cranking the master is key. The compression is prefect. The B channel suffers from not having its own EQ. I use the 900 mostly like a single channel amp.

[@LonelyRocker]

I likely use that clean channel more. I totally agree. But I dig in to the high gain channel when recording. It serves me very well. For live it would suffer with just the one EQ. That much I agree...

[@joeMW284]

@@LonelyRocker My preferred method is boosting the A channel. Any overdrive pedal will have a tone knob - that right there gives you more control than switching to the B channel for boost. I see this amp as having two selectable preamps in one box as opposed to it being a true channel switching amp. You gotta pick a channel and dial it in. Like you said, in the studio it doesn't really matter that much.

[@LonelyRocker]

Your A method is predominantly what I also do with this amp...for high gain I just got something new. Stay tuned to the channel!! :)

[@Polyphemus.]

My first 'proper' amp at 19 yrs old was a 900 SL-X (2100) and 1960A. I was pretty clueless, I'd started playing in the 90s during the era of small multi-fx floor processors and didn't really understand massive tube amps, channels, gain structure, etc. In order to maintain my regular 'super clean + high gain metal' setup I ended up running my Digitech RP-7 into the front with the pre amp gain turned as low as I could get it and the master turned up to get it as loud as I could. I couldn't understand why I wasn't getting a good sound out of it! 😂After figuring out I really wanted two channels, I eventually ended up selling it a few years later and moving on to other stuff.

[@LonelyRocker]

I'm sure we all have stories like that. When I was gigging back in the 90s with my 900 I bought a solid state preamp and pushed that into the front of the 900..I had NO CLUE what I was doing!!!! But we all have to start somewhere!!! :)

I’ve gone through numerous sets of tubes, replaced the filter caps and changed the speakers out several years ago. I’m a little disappointed that your video doesn’t show how “clean” this amp can get. It’s as good as my fender 68 DRRI, I suppose that’s more about the guitar and player. If you’re just playing hard rock, then the JCM 800 is your amp. But if you’re a serious player, working numerous genres of music (rock, country, blues) I’d say that 900 is a pretty damn good amp to accomplish that. I’ll see you all from the stage.

I never really like it. Im still not sure why... 10 years later, I put some 6l6 tubes it in, and it mellowed out a bit, but still, never really loved it. It's in the shop right now getting looked over, and Im hoping my tech can make it sound good... I mainly play a fender twin reverb now (for the past 20 years). I have effects that can make it as dirty as your mind can imagine. I can say that In all honesty that when I played that fender amp in the store, I had to own it... I have high hopes for the marshal, but the jury is still out...

[@LonelyRocker]

Amps are all so different and our tastes vary. We also all have different expectations of our amps. That sound in our heads. It makes it tricky and why I think these debates are silly. It’s likely just not the amp for you. You’ve always known it. You likely wanted to enjoy the amp but never found the tones you were looking for.

[@JeremiahL]

@@LonelyRocker I agree, that amp probably isn't what I was looking for. It's also possible that I never put anything into dialing in the tone, or understanding that turning everything up to 10 isn't the right way to approach it. I pretty much learned how to play electric guitar in isolation, and there wasn't the internet at that time to learn from. Also, at the time I was living in Iceland, so I mail ordered it and never even played before putting down $1200 (really stupid)... Kind of a slow motion train wreck in progress. Its funny that you mention the pqassionate gear debates. I see this conversation everywhere in life. Ford vs Dodge, marshal vs Fender, Marlboro vs, Newports... democrats vs republicans... It's kind of hilarious how people decide on something, double down, argue until they are red in the face, then just fall short of starting a religion over it. agreed, kind of silly. The Fender guys do the same thing... The black face AB763 circuits amps sell for $4k, and the silver face made the very next year (AB568) are considered to be dreaded, so you couldn't give them away...

if you turn down the gain and crank the master you can get the famous old plexi power amp saturation but hard to do at playable volume close by haha . but rh back end is the same topography as the old plexis, just the front end got adapted to try get more saturation at lower volumes, One thing thats interesting in a scientific way is if you put a plexi style or Vox non master volume amp on an oscilloscope and then a master volume , so say a jtm45 or JMP and then a 800 or 900 etc with the front end gain know the waveform from preamp distortion is a very sharp peak - hence why that sound can sound grating faster to the human ear than the non master volume amp that when in full saturation has beautiful curve at the top of the wave form on the scope, its as brutal as /\ (preamp gain) to O ( non master gain) and the human ear tires less and likes the softer peak, hence why the old plexis driven and pushed have a pleasing sound signature and richer, where our ears tire of the sharp preamp pushed tones, so ij designing any amp the trick is to get that sweet spot with volume and being able to saturate that power section, I think thats the magic in amps like the little freedman's and 1-20 watt heads where you can get the whole amp humming and not just a preamp diode on crack screaming at you .

Interesting! thanks for sharing!!

[@Glensully]

diode clipping is good at low volume. push pull pot solves the issue

[@LonelyRocker]

That is one way to solve it!

I run my 900 on the clean channel and crank it up all the way. The distortion it gets is just clean channel break up. It blows away the distortion channel. It’s not a ton of distortion but if you push it with a overdrive it’s amazing

[@LonelyRocker]

I love that clean channel and often do the same. Pushing a boost into sounds great.

[@NitroModelsAndComics]

Just rewatched and listened on better speakers. I am still not a 900 guy, but there are no real reasons to hate it.

[@LonelyRocker]

Thanks for diving in again. I think you nailed it. There’s no reason to hate it but it’s fine to say you prefer other things. That’s taste. Thanks for sharing!

I always loved the 900. It was excellent for punkish chugging. I loved the clean channel too. I also had an old jcm800 and it was completely different. I don’t remember it having a preamp gain, I remember it being incredibly loud and the harmonics were out of this world. On a whim, I set up a close mic and a room mic in a 3000 sq ft room and just played something to ring it out. That amp sang like Whitney Houston pre-crackpipe.

[@LonelyRocker]

The 900s get a bad rap but it's not fair. They are great amps. Man that must have sounded awesome. I hope you recorded it! :)

[@1thess523]

I am a 90's pop and skate punk guy and the 900 and Dual Rec were the staples back then 👍. My guitarist had a 900 but switched to an 800 after I left because he wanted more of a Jawbreaker sound, today I have a 90's 900 High Gain Dual Reverb 50w (6L6 tubes) and a 90's JCM 2000 DSL 100

When people say 900 they are not referring in general to the SL-X , they are referring to the standard 4100. The SL-X tends to spoken about (at least in the groups and communities I have been in) as a connected but independent entity. I do think the 900 gets an unfair amount of stick, but I am not sure of the way you framed this. The Debate is usually a debate regarding the Base models. When people say "i prefer the 800 to the 900" they are talking about the 4100

[@LonelyRocker]

I honestly think just as many understand it is the model number that matters as those who don't. The argument is too general. Like using Diode Clipping as a reason for not liking the 900. Much like the 800 some models have diode clipping and some don't. That was really my point...

[@Rubble1]

I’d probably buy 2 more 900’s before I ever got an 800 and I’d really o ly ever get a jcm 800 just to add to the collection.

[@LonelyRocker]

Love me those 900 fans!!!!

[@SonicDriveStudio]

Cool video man!

[@LonelyRocker]

Digging into the archives. Thanks man!

[@yrmthr]

Ive owned both and they are fantastic amps. I kept the 800 but the 900 is underrated, because of online lore and people not knowing how to dial in an amp

[@LonelyRocker]

Ding Ding!! Both good amps! Just different...love your 'tude! :)

[@ClearColorCloud]

I think the 2203 sounds better. As you said, it has a more articulate and open sound.

[@LonelyRocker]

That is a nice amp. No doubt.

[@JTHarrisHF]

Wanna know a secret? The power amp sections are basically both the same! So, grab a couple 900s as you can get them for less than the price of a single 800, then grab a Friedman IR-J preamp and plug into the return section of the effects loop...........and BAM!! KILLER Friedman/Marshall tone IN STEREO at like 1/5th the cost of buying 2 JEL100s or BE100s. Plus, you get to shock people with how good your JCM900s sound!! HAHA!
