They both sound great. Couldn't tell the difference listening to them on a phone. A question came up from a friend. I always assumed you had access to so much equipment because you work or own a store. The only other choice is you are the richest man in Sweden. Thank you for all you've done.

I have two 1959's from '70 and '71. They're les saggy and forgiving. Built on one chassis and only have the power amps left, they're still very heavy. Nice one again Johan, Happy New Year!

I had a a jcm 800 1959 cranked with a powerbreak, push the front end and I got lots of lovely warm gain with punch .

[@1sttvbn]

The JMP has a tad more brightness, and a bit more bite. Great review. Love the Les Paul tone. Would also like to hear a Strat through a Univibe on those two beasts.

[@timmbosliice]

Yay Johan is back to the JCM 800! I hope we get to see videos on the SC20 and how it compares to the real thing and other Marshalls. I would love to hear it played through some vintage greenbacks!

[@stevenlatch5286]

As a 2203 nutter I have a JMP, a 4010 combo, JCM2003 reissue, Kerry King JCM800. They all sound killer. Between components tolerance shifts, components and tube wear it's hard to really pinpoint where the small difference in tone originate from.

[@Heatfarmer]

Very nice to hear the small but significant differences between the mid-70's and ten years later.

[@alanst.4417]

Thanks for uncovering another hidden gem, Johan. Sonically I prefer the JMP a little fot its clarity and bite, but the JCM is very close indeed. Wonder if it's just parts tolerance, different bright cap or something else responsible for the difference.

[@bengtjohansson6364]

Johan and R9 is the right input for any Marshall! JMP for me: My type of sound, and it has a punch that I didn't hear in the JCM. I also think the JMP has better tone separation, or "clarity". The JCM had a more aggressive sound, when pushed. One their own they are both great amps, though. Different dialects, with the same roots. Thanks again Johan, and Happy New Year!

[@aquilarossa5191]

Happy new year Johan. I knew about them , because I had one during the 2010s. JCM 800 model 1987. Mine was made about '86 I think because it had the PCB mounted pots etc. 50 watts. I had it returned to stock by a tech, but it would not do the Plexi thing. Most do though. Mine was just a bit oddball for some reason. Very nice clean, but very high headroom and the breakup was not so Plexi sounding. Some of them have massive amounts of classic sounding crunch though. I know more about amps now due to channels like this and several others. I wonder if its 'stock' form was Superbass or something, so that's why it would not do the snarling kerrang Plexi thing. The tech could have also missed a component that was out of spec or something. It happened at Marshall sometimes, plus they get modded and messed with etc. I bought that amp and some other stuff with my refund from my new Randy Rhoads 1959RR amp that blew up pretty good after just a week. :( In 2014 I sold all my music gear to go chasing after a woman on the other side of the planet. Doh. I flew from NZ to Canada to set up an apartment on the US border just 20 mins drive from my new fiance. We got married but not long after her mother convinced her I was a Russian spy (even Russians think I am Russian for some reason). Seriously. I still have the emails of the mother in law accusing me. Family in NZ convinced me to immediately return to NZ in late 2016. I had zero guitars, amps, or pedals etc. Doh! I have finally rebuilt the hoard and exceeded it. A clone Plexi is my amp now. I run it into a Power Station. I am liking the new gadget though. A Friedman IR-X. Great for home use into DAW at lower volumes. It reminds me of Iron Maiden live and 'the moral of this story is not what to do when a bird...." 🤣 P.S. I think it may have been my instincts driving me. A last ditch second effort at another marriage in my 40s to not make my Dad 'extinct in the male line' like he used to joke before passing in 2022 (his Italian family tree stuff).

[@OgamiItto70]

Very interesting. They were surprisingly (to me) close. I wonder if the difference was slightly different circuit design, component age, different suppliers of components, component tolerance "stacking" or some combination of those factors? Most of the difference seemed to be that the JCM800 was darker than the JMP and the JMP seemed to distort a little more. Nice video.

[@JohanSegeborn]

Thanks! Yeah really close. But the additional sparkle of the JMP confirms my previous experiences of 800 and JMP.

[@OgamiItto70]

@@JohanSegeborn Due to internet forum tone dogma, I was expecting the JCM800 to sound like ass and the JMP to sound super-awesome, but that didn't turn out to be the case. Each has strengths and weaknesses. I might possibly even prefer the JCM800--it sounded smoother and beefier and might be slightly better as a platform for pedals. (Or maybe not, only in-person experimentation would really tell.)

[@simonmastromatteo5692]

Crazy how life is, I just saw one of those Super Lead 800 in my Canadian Marketplace on Facebook.. They sound amazing ! They seem to be more focused, less sag and squishy compared to the 70s one.

[@JohanSegeborn]

Thanks John, really good to hear that!

[@alvagoldbook2]

They sound nearly identical.

[@higherperspectivephotography]

Great comparison Johan. The 800s run slightly less plate voltage, and I think this is what's responsible for the more spongy tone. Ian Moss (Cold Chisel) used one of these 800 superleads for years (still does sometimes). His tone has always been amazing. In particular his solo stuff in the 80s. I think they're a hidden gem amp that no one really knows about.

[@zachariahwade8482]

He used a stock 74 Superlead in the early days. When I used to play Strats I was obsessed with his tone on the Your 13 live EP and bought a stock 74 Superlead but didn’t have an attenuator so had to run it clean(but still very loud) and out of all the Mossy tones the only one I could get close to was that spanky cleanish sound on Tuckers Daughter. I assume that was the 800 Superlead era(though he also used Fender Twins in the studio) I got most of the info on the 74 JMP out of an Australian Guitarist magazine interview about 15 years ago but I’ve seen it online. Such a shame there’s not much info on his gear(or any of the big Aussie bands of the era)

[@higherperspectivephotography]

@@zachariahwade8482 you can see the 800 hidden behind scrim on the Matchbook era tour (Hordern Pavilion show has it). He was still using it recently along side two Hiwatts. I have backstage photos of it from 2015ish

[@Johnsormani]

To me it sounds like a value difference in the bright cap . I don’t think the jcm 4 hole versions lasted long in the 80ies. Probably until the boards ran out and they started surface mount pots or even earlier

[@JohanSegeborn]

Thanks! I thought it was the other way around regarding plate voltage. Many of my JMP MK2 amps are from 1977 though

[@scottdunn2178]

Incorrect. Plate voltage is the same... it's the power supply on post-1985 JCM 100w models; they went from 6 to 3 electrolytic capacitors in an order to cut corners and save costs. This accounts for the "spongier" feel... the power supply isn't recovering as quickly. An 800 converted back to original 6 cap specs is punchier and has more balls and faster transient response.

[@07parachute]

Thank you Johan for the comparison. I'd go with JMP if I had to make a choice. great video as usual. Cheers!

Awesome work Johan! I just picked up a 1990 year 4 input JCM 800 Super Lead. It has been modded with a master volume. It has giant Mallory filter caps and 6550s. It sounds nothing like the one you are playing in this video or my old JCM 800 2203. It is very gainy and dark. It also does not clean up like a normal Marshall, perhaps because of the mods and old General Electric 6550s. I am loving it for the uniqueness but want the chime of a not-modded Marshall with EL34s. Any feedback would be much appreciated...THANKS!

Very cool comparison Johan. You should do a video comparing vintage round core nickel strings with regular modern ones. I thought the difference is negligible, but wanted to know anyway. The difference was significant and the missing ingredient in full vintage tone for me. They sound really fat in the upper mids without too much boomy bass or piercing highs. Cheers!

I have the beast - JCM 800, 1959 version, very loud but sensitive to EQ changes; with G12-65 speakers it sounds fantastic 😀

I just found one, it was modded with a master volume. Has old GE 6550 tubes and sounds great but not classic Marshall. Still, having an old Marshall with giant blue caps and huge transformers makes me very happy...

[@plumbummusic2051]

Actually prefered the mids from the 800 compared to the biting top end of the 76. It also seemed to have just a touch more gain, but not enough to turn into undiscernible mush.

[@JohanSegeborn]

I preferred the 800 for the solos. It had more meat in that range

[@Kashed]

Not that my opinion matters but, to me the 76 has that Frehley sound and sounds better when playing more nuanced chords or when there is a lot going on or you are picking often. It allows the intricacies of the notes be more transparent and would really work well in a live setting cutting through the band. The 87 sounds better with less complex changes and held chords. It sounds fuller and helps not sound thin when there isn’t much going on. Most people like this because they are used to practicing alone without a bass player or drums filling in the lower end. Either way they both sound good and would have their uses in certain mixes. Thanks Johan and have a Happy and Healthy New Year my friend. 🎸🤘🏻
