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
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.
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.
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.
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.
@@RDamps Very much so but if I was buying one now it would be a 50. I only ever had it on 10 once. I remember the volume on my guitar was off and I cranked the amp, that hiss. I ran a long lead out of the rehearsal room before turning it up, hitting an open e chord. It was a moment. Back in 88. :)
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.
Even though I now do this professionally, I still take my time. I don’t charge for the actual hours spent on my repairs. I treat every amp as if it was my own and take great care and time. Always accounting for human error to 🤣. Congrats on getting the DSL sorted. Superb amps that can be made better.
Where did they mount the choke? I have a JCM 2000 DSL100 and want to add a choke... but seems to be a tight fit wherever you might try and mount it. Regards 🎸
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
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
Hi. At just on 63 I'm learning to play bass and guitar 😁 I know but better late than to regret it when Peter at the gate says "what, the boss gave humans Marshall and you didn't use it" so may need help and advice 👍 Sounds like your from London so if I have questions about the 78 2203 can I ask or drop it in? Great playing, Aspiring. Ta Ian

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?
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 -
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.👍
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.
Yes! I usually have a quick listen with a pair of headphones too just to check it sounds good on those as well. In some videos you’ll see me wearing headphones. They are usually done in evening where I need to be really quiet 😂
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?
Changing the board shouldn’t change the sound at all as long as the layout is the same. Position of components has an effect on sound. Why does it need rebuilding?
@@RDamps it was token apart,to customize transformers(giving them different colors,which i liked) and through the concept,to make it servo and midi controlled.
This one it came in did have a little mod done but it was removed and put back to original. I did change the filter caps as they were leaking (physical and electrically speaking)
Not really, kind of 🤣 He used the 1959 Superlead modded to cascaded inputs (similar to the 2203/4). This and an MXR distortion + will get you pretty close. You would need Randy’s fingers to do the rest.

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

Thanks dude! They are first edition antiquities too. Signed by Seymour himself.
This is the best playthrough of these that I’ve heard - you really nail what it does best. Want one of these so bad!
These are wonderful amplifiers, and your exposition was well played and surprisingly sympathetic to the amp's endearing attributes.
Very kind of you! Thank you.

It really makes a difference!
Wow very nice demo! That's the Marshall sound for sure 👍
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.
No problem, happy to be some help
Awesome amp,i have the same one, ‘79 2204
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.
Do you regret selling it?
@@RDamps Very much so but if I was buying one now it would be a 50. I only ever had it on 10 once. I remember the volume on my guitar was off and I cranked the amp, that hiss. I ran a long lead out of the rehearsal room before turning it up, hitting an open e chord. It was a moment. Back in 88. :)
That sounds so, so good.
Thank you !
Sounds awesome..straight rock n roll
Strat into the low gain = awesome sauce
The best sound!

Great great job !❤
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. 🇨🇦
Very nice! 👌🏻
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
sounds amazing. wow ;O)
Just picked up a 78 combo version today! It’s pretty much the perfect Marshall tone!
Love the 2x12 combo’s. What speakers did I come with?
@@RDamps The stock Marshall Amplification speakers. I’m still trying to pin down what exactly they are. They sound great though!
@@ryanfulldark2775 Email me picture if you can buddy
@@RDamps Awesome, will do!
@@RDamps I sent the images lol
Great amp ! If you want THAT sound ... you have to take the JMP ! Guitar > cable > amp ... DONE ! :-)

Thanks! Yeah, not a mistake per se. but it is worth changing the screen grid resistors. It's pretty simple.

Great amp. Great tones. What does the sound come through to record the video after the Suhr and the reverb?
That is theeeee sound.
🔥🔥🔥🔥🔥
the amp of my dreams....

Honestly, the reissues are excellent. Check out my video of my 1987 reissue I modded to a 2204.
Hi ! Great tone,
Do you know where I can get one of these amps?
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 -

Could you please tell me what pickups are in this SG ??

Seymour Duncan Antiquities my friend.
OMG !!!! What a surprise ! Thanks ! You've got a killer tone my friend ! 👍👍
this thing sounds awsum!

Yeah that’s for the non master volume 4 input circuit. It’s not used on the 2203/2204 master lead models
@@RDamps Thank you for answering my question. I appreciate it.
It’s why I’m here 👍
I have a 1959SLP and I am jonesing for a JMP 2204
Very Tight Well Defined Tones/Harmonics . Transformers should be good , unless somebody let the smoke out ?
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?
Yes! I usually have a quick listen with a pair of headphones too just to check it sounds good on those as well. In some videos you’ll see me wearing headphones. They are usually done in evening where I need to be really quiet 😂
Sounds incredible! Can you share the specific IR you’re using?
Hi Brett, the IR on this was the stock 4x12 with greenbacks that came with the Suhr Reactive IR.
Thanks for this video.

Wished mine JMP would sound like yours.is it completely original or did you any mods?bright cap still inside?
This one it came in did have a little mod done but it was removed and put back to original. I did change the filter caps as they were leaking (physical and electrically speaking)
Really good tones… this is standard or modify bright cap (470pf)?
Standard.
@@RDamps awesome!!!
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?
Is it possible to put an fx loop in one of these amps?
Yes it is. There are some really good ones available these days too. They don’t destroy the amps tone like the older ones
Are you running el34s or 6550s in the output?
EL34’s sir!
Speakers here? (You may have said and I missed it.)
I’m using an impulse response of a 4x12 with greenbacks mic’ed with a SM57 and a Royer 121
You could get so much out of that amp and you decided to go with Angus Young's tone?
They should reissue this amp. I have the 2203X and it's too loud.
Exchange it, Get the 1987x and get it converted to a 2204. Its work I've done a couple of times. I will be doing a video on my personal one soon
The 2204 is only slightly less loud...like 3dB or so.
@@wakjob961 makes a good point, maybe exchange it and get the new 20w version of the 800? They sound really good to me
Get an attenuator!
Is this the same model randy rhoads used?
Not really, kind of 🤣 He used the 1959 Superlead modded to cascaded inputs (similar to the 2203/4). This and an MXR distortion + will get you pretty close. You would need Randy’s fingers to do the rest.
@@RDamps i knew used rhe distortion plus but i had no clue what amp he used and this one just looked similar
@@Person-cv9dj, it would have been a similar year for sure. Randy had the four input style ones.
@@RDamps oh i didnt realize i always thought it was the two input one so i thought this was his amp
what the speakers?
It is an impulse response of Celestion Greenbacks
Do you have a website or some way of me contacting you, please? 10-4, good buddy.
Check the links on my channel page.
@@RDamps - there aren't any, which is why I asked.
@@steveymoon , sorry for the delay. Hit me up at rubberducktechnical@gmail.com
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?
I use a load box and IR’s mainly for consistency in recording and also I like to keep my neighbours as friends 🤣
A "proper Marshall tone!"
10:20
They say the 79 jmp 50 watt are the best marshall
Definitely one of the best without a doubt
It's among the best for sure. I had the 100 watt 2203 though. It was amazing and earth shattering
