re: The MarshallForum Guide to Marshall Amps

I purchased this amp a while ago and was trying to determine what model Plexi it is. It is a 1997 limited edition 50 watt Plexi it has the MK11
on the front panel and on the back of the amp it has a gold plate
that says 1997 limited edition with Jim Marshall's signature.


I think it's a super lead? Anyway I contacted Marshall requesting
information on it. I was wondering If anyone else has this amp?
Thanks for all your help.

re: The MarshallForum Guide to Marshall Amps

Hi.

I'we have a AVT 275 for 3 years and i'm very satisfied with it.

but, in the effect loop i use some components like dig effects..etc, so my problem is how to connect a usual midi foot controller to control the AVT 275 and the effect in once, because with the regular AVT 275 controller it is impossible to control the components by MIDI inputs, and it would be stupid to have two controllers, and otherwise I have to change the effects by hand or use all the time just one combination.

the connector for the Marshall is a flat comp one, so i bought a cable (adapter) with midi in-out on one side and this Marshall connector in the other side, rent a midi foot controller and connected it. The result was total failure, error in the Marshall channels, so i realize that the Marshall connector is probebly in some unicat sheme which doesn't match with the usual midi shemes.

My question is- is it posible ti connect it, it is not a problem for me to make that cable adapter by myself, but does any one know the sheme if it is posible to connect it that way!

I'm from Croatia, so please sorry about any spelling mistakes.

re: The MarshallForum Guide to Marshall Amps

The Lead and Super Lead models 62 - 81:

Model 1987:
JTM-45 MkI prototype
JTM-45 MkII: The JTM-45 for sale 62 - 66
JTM "reverse logo" (50w with EL34) late 66 - mid 67
JMP Plexi mid 67 - mid 69
JMP Metalface mid 69 - 81 (up to '84 some places)
Tremolo model 65 - 75

Model 1959:
JTM-45/100 with KT66 introdused November 65. The last of them changed to EL34 tubes.
JTM "reverse logo" late 66 - mid 67
JMP Plexi mid 67 - mid 69
JMP Metalface 69 - 81
Tremolo model 65 - 73

JTM MkIII was the 50w Super PA model 1963 (the only JTM50)
JTM Mk IV was the Tremolo version
JTM Mk V was the 100w Super PA model 1968 (the only JTM100)

Tube rectifier on the 1987 until early/mid '67, 100w never had it.

Excellent post, thank you very much! Aspen Pittman's tube amp book goes into detail about Marshall. I dig the way you've historically laid it out.

Hi there, I've just registered with your fine site and I'm not even sure I'm posting in the correct place, so please forgive me if I'm not.....but I have a question regarding a Marshall Amp...I am...(gulp)..actually a drummer. Any how I aquired a re-issue Super Lead Mk2 100 watt some years ago, I sent it to Marshall to be serviced a month back and they told me it was in pristine condition, only needed a couple of new pre-amp valves. it is covered in the original white tolex with gold piping and the smaller Marshall logo on the front, and is and looks in brand new condition. The serial number has been pretty much obliterated over the years, but they think it is a 95' or 97' re-issue?..would anyone know what these are worth? I've looked on the net and can't seem to find this model. Cheers for your help

re: The MarshallForum Guide to Marshall Amps

Not a very comprehensive list.
What about the JTM30, JTM60 & the Series 9000 19" rack system amps as well as the Split Channel Reverb, the PAs, the Bass range, the Mosfet early attempts at solid state (historically very important), the Valvestate series as well as the current MG models and the little practice amps? Even the JCM2000 series were omitted.
If you're going to have a list of Marshall's models then let it be comprehensive, don't leave any out, make it interesting, a history lesson on Marshall.
Some were good, some great while others were awful but they were all important in describing the history of the development of Marshall amps while this small list tells us nothing.

On the 201 and 401, the Master Volume for the whole amp is on the far right of the faceplate, next to the on/off and standby, but if you don't have the gain turned up for the clean (green) channel, you'll get nothing because that's what controls the volume for the clean. If you crank the gain on that channel, you can get it to break up a little, like the classic amps of old.

If this isn't the problem, like you have no sound on any channel or something, it may be the bridge rectifier or a tube issue. You may want to repost this question in the Workbench thread, as it can be seen easier and you'll get more help in the future.

You might swing a Mode Four head for that much, but it pushes 350 watts, so you'd need the cab that goes with it (it handles 400w I believe).

re: The MarshallForum Guide to Marshall Amps

well Im quite new to this forum and dont know if this is the right place for my question. But since it's about amps, I'll just shoot and see who gets back to me:

Just bought a TSL 100, dont seem to be able to get a good sound yet. The manual says I cant connect distortion to the loop. Is this correct? I would love to connect my Metal Core.
The crunch channel sounds awful and the lead channel doesnt impress me. (Why did I buy it? Long story, lets not go there).

Also, does the amp supposed to be this way that the clean channel leaks into the cab, even if vol. and gain controlers are on zero? Only after you switch to the OD channels, does the clean sound stop.

re: The MarshallForum Guide to Marshall Amps

To all three previous posters:

Go up to the Marshallforum image in the top left corner of the screen. Click that, and then look at all the categories available to post in. Choose the one that best describes what you need/are looking for. Click it, and on the left side above the existing thread list, there is a "New Thread" button. Go and do that, or you might not get any more responses in this old thread.

amirali: The TSL is complicated but many guys here get awesome sound out of it, so repost in the Marshall Amps section.

broberts: Same for you. That head should sound good thru a cab; someone else here already did it. Just match the ohm settings.

mhbilt: You too. Marshall Amps section.

Hope this helps you guys.

re: The MarshallForum Guide to Marshall Amps

These are some pictures of the new MARSHALL JMD:1 not in the official page from Marshall. Sounds Great......
Are made in china 100 Watts 4 valves for amp and one valve for preamplifier, 2 speakers different each one, Sounds really good as MARSHAL SOUND, I think has been made to compete with LINE 6, has a foot switch, 4 channels, can be connectec to a cabinet.

re: The MarshallForum Guide to Marshall Amps

I dig this link. I've always been appreciating all the info I read about Marshall amps. Although I own 5 amps, (four tube, one solid state) I still am debating which Marshall I should get. I don't have a Marshall yet! I'm considering the new 5 watter the Class5. I've heard it is loud even for a bedroom practice amp!

Exclamation re: The MarshallForum Guide to Marshall Amps

Hi i have a jcm 900 with a 2x12 cab. Ive bought it second hand, its in really good condish. Recently at a gig its started to cut out at high volume levels. It doesnt cut out completely you can still hear the slight mutter of it. I have no other fx pedals going through it just Directly into the amp. Last night at practice i took the back off my head to see whats what...

The valves are still glowing nicely and everything seems normal with the pots etc, no evidence of faulty wiring...

I ruled out that its the head thats the problem, so i went to work on the cab. Usually i have 2 Jack leads going from the cab to head to give it a stereo format. I tried it with one instead to make it mono and it works better but it still cuts out just at longer periods. Whats the problem???????? The speakers seem fine ive tried various leads, My gibson SG is nearly new so its not that. I really dont know its my first marshall and if im honest i dont really know enough about them to make an informed decision but on the other hand i dont want to spend a fortune to get it looked at if its something simple.

HELP!!!!! Many Thanks

Nick

This is just some information about the main BIG Marshall tube amps. It is not a definitive guide or something like that. Just some points to help to understand the different models, what they do, and who uses them.

There are some other important models (18w, JCM600, newer models…) and there were also Bass/Super Bass versions of the 50w/100w amps. Then PAs… but below are the real BIG Marshalls.

Marshall has done different RIs in recent years (as you may know).

JTM45 / Bluesbreaker combo

- Introduction: 1962
- Models 1987, 1961 (BB with 4x10”) & 1962 (BB with 2x12”)
- Tubes: 2x5881 & 3xECC83
- Used 6L6GT whenever supplies of the 5881 dried up
- From Jan/64 to Dec/65 due to a problem of supply with the American tubes Marshall used KT66 being the tone more crunchy. Let’s say more “Marshall”
- The front panel reads JTM50 (Jim and Terry Marshall – Terry is Jim’s son)

PLEXI PANEL

- Introduction: 1966
- Models 1987 (50w) and 1959 (100w)
- Power tubes change from KT66 to EL34
- Character: Tighter, louder and fuller distortion
- The front panel reads JTM
- Hendrix, EVH, ACDC etc…

METAL FACE

- Introduction: 1969
- Change from Plexiglas to gold aluminium (front and back panels)
- Circuits remain PTP (and therefore the same as plexi models) until 1974
- Character: From 1974 (printed circuit board) brighter, more aggresive and less harmornics.
- The front panel reads JMP (Jim Marshall products)
- 70s classic rock

MASTER VOLUME

- Introduction: 1975
- Marshall included a preamp gain control
- Character: Bright and punchy. Real screamers
- Iron Maiden, Judas Priest (old), Black Sabbath…

JCM800

- Introduction: 1981
- 1 channel model: Just cosmetics changes
- 2 channels model: Channel switching, reverb and effect loop
- Character:
+ 1 channel: same as master volume
+ 2 channels: More gain and more aggressive than the single channel version

- Zakk Wylde, Motley Crue, Tom Morello…

Silver Jubilee

- Introduction: 1987 celebrating 50 years in music and 25 years in amp industry
- Pentode / Triode switch
- Gain mode switch
- Character: Dark and more gain than a JCM800
- Slash

JCM900

- Introduction: 1990

- 1 channel model (Hi gain master volume)

+ 1990: 2500 (50w) and 2100 (100w) – More gain (up to 20) and dual master volume
+ 1993: 2500SL-X and 2100 SL-X – Extra ECC83 (more gain)

- 2 channel model (Hi gain dual reverb) – 4500 (25 or 50w) and 4100 (50 or 100w): Channel switching and dual reverb

- Character: grungy & more metal tone
- Dave Navarro, Pete Friesen, Jane’s addiction…

30th ANNIVERSARY

- 6100LE: Brass-plated chassis. Limited to 800 units worldwide
- 6100: EL34 tubes
- 6100LM: 5881 tubes
- 4 x EL34/5881 and 7 x ECC83 = 11 valves!!!!
- 3 channels – Tried to produce the tones of all great Marshall amps

+ 1: Clean (JTM45)
+ 2: Crunch – 3 positions: Superlead / Master volume / JCM900
+ 3: Gain – 2 positions: Super gain / Super Ultra gain

- 4 way output power switching: You can select Pentode or Triode & 2 or 4 output valves meaning 25w, 50w or 100w depending on your selection.
- Serial / Parallel effect loop with trim controls on each channel
- Balanced compensated output
- Speaker emulator
- Output valve protection circuitry
- Character: Every character?
- Joe Satriani, Johhny A.

Hope it helps. Sorry if I left something you consider important.

I guess JCM 2000 series aren't real Marshalls then eh? I feel so depressed and inadequate....
