Great sounding Amp, brother. Those SD Antiquity Pickups sound amazing.

What can I say? The best amp ever built. I'm so lucky to own two of them. Just add a booster for leads an d no one needs multi channel amps anymore.

I’ve had that amp (a ‘79 as well) forever and was always wondering why it was less gainy than what I’d hear from others using it. Blew a tube and took it in for service and finally found out it was modded to a plexi type circuit. I basically always used pedals for dirt. I can’t wait to bring it home soon as my tech has restored it to its former stock glory with a Van Halen mod to give it a touch more gain. I can’t wait

quintessential marshall sound .bravo..

Glorious tone. Further proof that all the best Marshall’s have six knobs!

I own a 1978 Marshall JMP that I bought used at MachineHead Music in Hitchin. Bought, probably in 1991, it is modified input, so no jump cable needed. I also bought my 1989 Les Paul Standard from Geoff, as well as some Marshall cabs. I met Terry Marshall at Machine Head as well and incredibly was invited to the Marshall factory. I've toured it several times. I'll never forget how nice all the guys at Marshall were, to a young Airman in the USAF, stationed at RAF Chicksands.

Always good to see you on this stuff. A little old, but its watchable over and over. Hey have not seen much new stuff from Marshall for some time and I think its the pandemic blues etc. Regards.. T.

Bright, bitey and squishy.... Beautiful tone.

This is the best playthrough of these that I’ve heard - you really nail what it does best. Want one of these so bad!

Gotta love some good Antiquities. Had a set in a '95 Explorer I used to own. In my opinion they nail that P.A.F. tone. And before anyone asks me, I've played a Max Les Paul with real P.A.F's into a Bogner Helios. Killer sounding amp man.

These are wonderful amplifiers, and your exposition was well played and surprisingly sympathetic to the amp's endearing attributes.

Thanks for this nice clip. I bought a 4 hole version a few years back. I need to go over a bunch of the wiring/caps/resistors to make sure it is sound condition again.

I own an '80 JMP and by the sound of this video, I really need to take mine in for service! :)

Extremely useful video, I have had my 1979 JMP 50 since new. I just biased mine up with Mullard reissue pre and power tubes and it roars. The low input option is extremely helpful and yes, sounds very much like a plexi. I am getting a lot of idle hum with the amp pinned however. I've gigged and recorded with this amp and it is fantastic. I try to get it up into its power curve like, 4 on the pre and 6 on the master.

Great video, thanks for show me the mods and caps and things that need to be changed. I will share this with my amptech who is repairing mine at the moment.

Wow very nice demo! That's the Marshall sound for sure 👍

Sounds awesome..straight rock n roll

That sounds so, so good.

Awesome amp,i have the same one, ‘79 2204

The best sound!

Great great job !❤

My first good amp I had was the 100 watt version I bought in 1986. Bought from a friend for $800. Long gone now,. Cranked to 10 just once.

Strat into the low gain = awesome sauce

sounds amazing. wow ;O)

I have a bone stock, very low hours 1983 2204 Canadian 1/2 stack. Of my 20 amplifiers this is my favourite. Killer tone and spanky response. 🇨🇦

Couldn't help but notice the Albuquerque shirt - I live in Roswell. Like the amp service/mod channels as I dabble in that a little. Have several Marshalls including a '98 DSL50 which I read about on the forums as potentially having problems. Checked the chassis versus the schematic and sure enough some component values were way different. My amp worked fine except sounded a bit mushy to my ears. Decided to risk the $500 investment and mod the amp - changing component values and doing some mods described as "Joey" mods. I ended up replacing about 33 components, added a choke etc. I held my breath and was ready to cut the power should anything smoke, flame, or explode. I was very careful, had gone to school for electronics (decades ago) but am not a pro level solderer. Switched it on, let it sit a while, biased it - and whaddya know everything worked! It sounds tighter, punchier and is dead quiet at idle. Cannot emphasize how slowly and carefully I proceeded, with many notes and pictures.

Just picked up a 78 combo version today! It’s pretty much the perfect Marshall tone!

Great amp ! If you want THAT sound ... you have to take the JMP ! Guitar > cable > amp ... DONE ! :-)

Good amps. I had one. 78’. The only thing I don’t like so much is the super low plate voltage from the PT. Mine was around 390v. Makes the amp a bit mushy. It can’t take too much gain or it gets more mushy cause of the low headroom. Pretty sweet sounds from it tho. Nice man

That is theeeee sound.

Great amp. Great tones. What does the sound come through to record the video after the Suhr and the reverb?

Nice video and great sounding amp! I just did the same thing to my '78 2204. I didn't do the resistors though. I hope I didn't make a mistake not doing this? I know the feeling of having your kid help out with your channel. My son gives me invaluable advice that make my videos better for the viewer. cheers

this thing sounds awsum!

Wow ! Sounds awesome ! No frills ! This is the exact tone I've been after for years ! This guy can rock and has a part of the tone in his fingers. Could you please tell me what pickups are in this SG ?? Thanks in advance.👍

Hi ! Great tone, Do you know where I can get one of these amps?

I have played most newer Marshalls and was so lucky to get my hands on one of these. These amps sound incredibly well. I have never played through an amp with such good tone before. I don`t know what they put in these amps at that time. I just know they should do it again. Are the components they used in these amps still available/ massproducable?

I have a 1959SLP and I am jonesing for a JMP 2204

the amp of my dreams....

Hey, sounds great. So, when you run through that IR you're hearing the guitar through a pair of speaker monitors hooked up to your DAW?

🔥🔥🔥🔥🔥

Great sound man !! - I just got my recently purchased '79 2203 off of my bench. Added a few simple mods. This thing is a brutal MONSTER !! - Where did you get that t-shirt ?? I love it !! - I'm from New Mexico -

Sounds incredible! Can you share the specific IR you’re using?

Wished mine JMP would sound like yours.is it completely original or did you any mods?bright cap still inside?

Thanks for this video. I own a 1979 Marshall 2203,which has to be rebuild.All original parts are still there,but i'm guessing about some futures on this one: replace the board to a hardwire version with other parts(like mustard caps),post phase inverter and pre phase inverter master volume option and a midification to all the pots,with storage of settings.Do you presume that the board changing,will change its sound dramaticly?

Such a great sounding amp!!! Great playing too!!! And, the Suhr IR does an incredible job. I noticed that the amp is missing a 300m (I think) resistor, it is the second slot from the left side in your video. I've seen others with that slot empty. Do you know if people take those out or if they are just not installed from the factory? Great video.

Really good tones… this is standard or modify bright cap (470pf)?

Very Tight Well Defined Tones/Harmonics . Transformers should be good , unless somebody let the smoke out ?

Are you running el34s or 6550s in the output?

Is it possible to put an fx loop in one of these amps?

Cut out that damn bright cap on the preamp gain! I also add a small switch to bypass the first stage treble bleed R/C network. Great sounding amp.

Ever notice how some channels get copyright strikes and others don’t?

Speakers here? (You may have said and I missed it.)

You could get so much out of that amp and you decided to go with Angus Young's tone?

Is this the same model randy rhoads used?

what the speakers?

They should reissue this amp. I have the 2203X and it's too loud.

Why are you using a "IR"? Why not just plug the head into a cab and let her rip? Aren't you essentially running the head through a digital signal?

Do you have a website or some way of me contacting you, please? 10-4, good buddy.

A "proper Marshall tone!"

They say the 79 jmp 50 watt are the best marshall
