Dating a marshall amp. TaylorScott posted this 16 May 2012. My amp tech sent me my amps serial number for my records, and I started trying to double check the date of the amp. I believe it is a 1984, but I can't say that for certain. I was using http://www.blamepro.com/mar/date1.asp. To help shed some light on how marshall serial numbers works. In the long run, I think I just confused myself. My amps s/n is S19321. Useing the abuv link, I'm not sure if the S stands for the year 1984, or the 50 watt model. :( Any marshall guys, or anyone who can make sense of this, your input is welco .
Marshall amplifiers made hard rock possible. While Fender and Vox amps have their place in moving electrified guitar forward, the creations of Jim Marshall fostered an entirely new sound and allowed guitarists to fill stadiums with it. Marshall amps had such precedent-setting wattage and tone that their history can hardly be separated from the history of rock itself.
We recently wrote an article detailing that rich history (which you can read here), but for those simply looking to figure out how old their Marshall amp is, we offer this shortcut. The guide below will help you quickly and clearly date Marshall amps and cabinets, without us waxing poetic about their influence. Before we begin, a few caveats: • Marshall model numbers look like years.
If your amp says Model 1986 on the inside, that does not mean it was made in 1986. This is probably the biggest area of confusion when dating Marshall amps. • True serial numbers weren't really used by Marshall until July 1969, so specimens made prior to that can only be accurately dated to a fuzzy span of several years.
• All Marshall amps originally came with Celestion speakers, so in cases where the speakers are original, can be used to date earlier amps. • Marshall cabinets didn't officially include serial numbers until October 1992. As a result, dating cabs can be more art than science. The best approach is to cross-reference the serial number with known features for the model during different eras and the personal account of previous owners.
Getting the correct year is one thing, but getting the story behind an amp is the fun part. The guide for that is much simpler: be nice, ask questions, offer beer. Marshall Amps By Series If you have absolutely no idea whether your Marshall is old or new, a good place to start is the model name or series.
This will give you an approximate idea of the era during which your amp was manufactured. It's also one more piece of evidence to pair with the serial number to corroborate the actual year. The first Marshall amps were made in England starting in 1962. Production has continued there uninterrupted through today, though some lower-priced models are now made in China, India or Korea, depending on the series.
JTM-45 Models: 1962 - 1966 Bluesbreaker Combos: 1964 - 1972 Four-Digit Models (no series): 1965 - 1981 JCM 600 Series: 1997 - 1999 JCM 800 Series: 1981 - 1991 JCM 900 Series: 1990 - 1998 JCM 2000 Series: 1998 - 2008 Silver Jubilee Series: 1987 - 1989 30th Anniversary Series: 1992 - 1999 JTM Series: 1995 - 1998 35th Anniversary Series: 1997 only Solid State 5000 Series: 1984 - 1991 Valvestate Series: 1991 - 2000 AVT Series: 2000 - 2007 Mode Four Series: 2003 - 2008 MB Series: 2006 - 2012 Hand-Wired Reissue Series: 2004 - present JVM Series: 2007 - present Vintage Modern Series: 2007 - present Haze Series: 2009 - present MA Series: 2009 - present MG Series: 1999 - present JDM:1 Series: 2010 - present Some amps won't fit into these series (like the recent Class 5 Combo or various signature and limited edition models), so using the serial number will be your best bet to hone in on a specific date of manufacture.
Marshall Serial Numbers To find the serial number on your Marshall amp, start by looking at the back panel of your amp. For models made between 1979 - 1981, the serial number will be on the front panel.
Keep in mind that no reliable serial number information exists for pre-1969 Marshall amps, so if your amp doesn't have a number matching one of the formats below, it is likely pre-1969 and identifiable by features rather than serial number.
Click on the links here to jump directly to the serial number style that matches your instrument: • • • • • • Early Models: 1962 - 1964 The earliest Marshall amp models did not have model codes or any official serialization, though some models had a simple sequential four-digit numbering system inside the back panel.
These numbers supposedly started with 1001 and progressed from there, starting with 2001 at the beginning of 1964. Often these specimens produced between October 1962 and December 1964 had an offset chassis. Look for original black levant covering, a gray grille and the old block-style Marshall logo. Model Codes Without Serial Numbers: 1965 - 1969 From January 1965 to June 1969, model codes were used but no known serial numbers accompanied them.
This era saw the advent of Plexiglas panels (giving rise to the "Plexi" name) and four-digit model numbers. Amps from this era still have the block-style Marshall logo and a centered chassis. The model codes below should help you identify which model you have, while the characteristics described for each year should help with dating.
• Cream back panels • JTM-45 block logos changed to gold-plated plastic script (these are rarely original, as they broke easily) • Small round gray cabinet feet • Plastic handles with larger ends compared to earlier models • KT66, 6L6 and 5881 tubes in the power section • RS Spares or Drake transformer used in the JTM-45 (the Drake rated at 8000 ohms) • Some JTM-100 amps appear with the JMT-45 badge in late 1965 (check for two 50W transformers and a solid state rectifier) 1966 Features • Larger black cabinet feet circa July '69 (earlier feet were small and gray) Model Code-Serial-Date Code: 1969 - 1983 Starting in July 1969, Marshall starting using official serial codes.
They were initially broken down into three parts: the model code, the serial production number and the date code. Marshall used letters as a date code to represent year of production. It's important to note that, prior to 1984, this letter came last. The letter B was skipped, as were the letters I, O and Q since they might be confused for numbers. Use the model codes and date codes below to determine the model and age of your amp.
For example, the number S/A 8481 E tells us that this is 50W amp (S/A) made in 1973 (E), production number 8481. Model Codes J 1977 K 1978 L 1979 M 1980 N 1981 P 1982 R 1983 Model Code-Date Code-Serial: 1984 - 1992 From January 1984 to September 1992, the three-part coding was used by Marshall but the date code letter was moved from the end to the middle.
The same model codes from the previous section of this article still apply, although the model code "RI" is also seen for reissues. The additional date codes for this era are below. An example from this era might be SL/A X 10059. This would indicate a 100W Super Lead (SL/A) built in 1989 (X), production number 10059.
Date Codes 1984 - 1992 W 1988 X 1989 Y 1990 Z 1991 - 1992 Nine Digits On A Sticker: 1992 - 1997 Starting in October 1992, Marshall moved away from stamped metal plate serials and began using stickers with a xx-xxxxx-xx format serial and a bar code.
Cabinets had serials at this point as well. The sticker-based nine digit scheme lasted through July 1997.
These serials are much easier to understand, as they don't include any model or date codes. • The first two numbers indicate the last two digits of the year of production. • The middle five numbers indicate the production number. • The last two numbers indicate the week of the year (01 - 52), out of 52 weeks. For example, the serial number 961002334 would tell us that this amp was made in 1996 (96), production number 10023, and it was made during the 34th (34) week of that year.
Letter-Ten Digits-Letter: 1997 - Present Starting in August 1997, Marshall moved to their current serial number scheme, which is easier to understand and gives more information than previous schemes. These current serial numbers are arranged in a letter-ten digits-letter format (A-xxxx-xx-xxxx-A). These are still found on stickers with a bar code on the back of the amp. • The first letter indicates where the amp was manufactured (M for England, C for China, I for India, K for Korea).
• The next four digits indicate the year of production (1998, etc.). • The next two digits indicate the week of the year during which the amp was produced (01 - 52).
• The next four digits indicate the production number. • The final letter indicates the voltage setting (for use in different countries - see table below).
For example, a serial number of M-2002-38-1035-B would indicate an amp made in England (M) in 2002 during the 38th week of the year, production number 1035, set up for use in the United States (B). Voltage Codes A 230 Volts (UK) B 120/60 Volts (US) C 220/50 Volts (Canada) D 105/50/60 Volts (Japan) E 220/60 Volts (Europe) F 130/60 Volts (Mexico) Z Speaker cabs (no voltage) Celestion Speaker Codes: 1963 - Present If the speakers in your Marshall cabinet or combo are original, they can provide another piece of evidence when determining the date of manufacture.
As many cabinets did not have official serial numbers before 1992, this can be especially helpful in dating earlier specimens. Marshall has always used Celestion speakers standard from the factory, and thankfully, Celestion has been very consistent in coding their speakers.
There have been three coding schemes used by Celestion since Marshall's birth as a company, each using some combination of day, month and year. Using the month and year codes below, and knowing what order they are in for different eras, you can easily decode a Celestion speaker's age. Example: In the mid '60s the order was day-month-year, so a code showing 13DL would indicate a speaker made on the 13th of April, 1966.
The month codes below remained consistent from 1963 forward, but there have been several eras of year codes. Check the era below that applies to your speaker. Celestion Month Codes A January B February C March D April E May F June G July H August J September K October L November M December Celestion Year Codes: 1963 - 1967 During this four year stretch, Celestion speaker codes followed a day-month-year format. For example, a 12KM code would indicate a speaker made on the 12th of October (K) in 1967 (M).
See the year codes below through 1967. The year codes changed after this, so using other pieces of evidence to make sure you have pre-1968 speakers is important. If you have a speaker older than this, the year codes move backwards through the alphabet to A, which would be 1956.
N 1980 P 1981 Q 1982 R 1983 S 1984 T 1985 U 1986 V 1987 W 1988 X 1989 Y 1990 Z 1991 Celestion Year Codes: 1992 - Present Currently, Celestion speaker codes follow a day-month-year format. The year codes started over, with 1992 beginning at B, oddly enough. An example code from this era might be 21KC - a speaker made on the 21st of October (K) in 1993 (C).
N 2003 P 2004 Q 2005 R 2006 S 2007 T 2008 U 2009 V 2010 W 2011 X 2012 Caveats, Exceptions, Gratitude The serial number is one part of the puzzle when dating an amp, but cross-checking the originality of the different parts, including tubes, wiring, transformers, knobs, etc. is just as important. If you're about to put down a hefty sum on a vintage Marshall, we strongly encourage you to consult multiple sources to determine the exact age and originality of the amp. It should also be noted that there may be some signature models and limited editions that will vary slightly from the Marshall serial number formats described here, but in general, determining the year will be the same.
We can hardly express enough how grateful we are for the hard work that the good folks at Vintage Marshall Amps website, Michael Doyle and Nick Bowcott, all of whom have done an immense amount of work to increase the accuracy and availability of information on Marshall amps.

If your goal is to find the best practice amp for a budget price and therefore the best Marshall for the same price, the MG15F is the one that you’ve been looking for. Once again a part of the renowned MG series, this amp packs a neat total of 15 watts of power delivered through a single 8-inch speaker. The device features an Mp3 input and a headphones input, something beginner players are bound to appreciate, along with standard two channels for rhythm and solo performance styles.

The product’s total weight is around 16 lbs, making it quite easy to transport. If you happen to be an aspiring rock guitarist yearning to reach the heights of Jimi Hendrix and Eddie Van Halen, this is the best starting point we can think of. Marshall JVM 215C Product prices and availability are accurate as of the date/time indicated and are subject to change. Any price and availability information displayed on Amazon.com at the time of purchase will apply to the purchase of this product.
And in the high end department, we bring you the guitar amplifier that proudly boasts the title of the best Marshall combo amp period in our book – the JVM 215C.
It’s a 50 watt all valve tube amp sporting a set of five 12AX7 tubes and a pair of EL34s. The amp () can deliver a tremendous amount of power. When they say that a tube amp can deliver 10 times more power than a solid state model with the same wattage, one could say there’s truth in that.
Anyhow, it’s not all about the raw power, but the sound quality, and boy does this guy have it. The single Celestion 12-inch speaker and two fully independent channel pack a truly impressive amount of sonic authenticity. We’re talking crunchy middles, bright treble, and a bone-crushing low end.
When you read about the “iconic Marshall sound” online, those reviewers and audiophiles are referring to amplifiers like this one. The amp offers a Clean / Crunch channel, and an Overdrive channel, along with a built-in reverb and on-board Resonance and Presence controls.
When you add a foot-switch to the mix, the device becomes very user friendly and easy to control. “So why Marshall?” One of the top reasons for opting for a Marshall amp is the fact that they didn’t water down their formula for the sake of easy profit over the years.
Sure, they have an iconic status, but they also still deliver that same vibe of their most successful products, and even strive to improve it every now and then. You can always count on them to deliver what they’re known for – the crunchy hard rock vibe that shook the world and helped start a musical revolution. If that’s not your thing, there are other quality manufacturers to suit your needs, but if your heart says you’re a rocker, these amps were made for you.
“Can I use a Marshall combo amp for live gigs?” Depending on the model, yes, absolutely. If we take a look at the items listed above, a JVM 215C can crush a live gig, and a DSL 40C can also do the job just fine. The DSL5CCW can handle a smaller band practice or a jam session, while an MG 15CF stays what it is – a top-notch practice amp and not a live performance amp.
Hopefully we’ve been of some use to you here, kind reader. If buying the best combo amp sounds like your thing, we wholeheartedly advise you to get one of these pups now and start rocking ASAP.

And they kinda of suck. That isnt neccessary. Go with a good ol' tube head and your set for life. Epiphone Goth Les Paul Studio Ibanez SA120 Peavey Raptor EXP Takamine Electric Acoustic Boss CS-3 Boss DD-6 Boss TU-2 Boss MT-2 (For use with my Vox) MXR M-108 10-Band Eq Dunlop Crybaby Wah Peavey JSX Head Vox AD50VT this isnt for me, i play bass and use fender amps.
theres just this guy in my class that plays guitar and everytime i ask him what amp he wants, he just says the BIGGEST marshall amp, and now im asking to see which is the most powerful and biggest so i can find a pic of it and show him..he doesnt even know what a head and cab is..... Yea...that's believable. I know someone who has a Marshall too, and when he said he had jsut got it I asked him what kind, and he didn't know but he said it doesnt matter cause its loud.
Hmmm... Anyway, the Major 200 will probably be the loudest. Sound City made a 200 around the same time too. Used the same KT88/6550 setup, and had pretty much the same features, as well as having Partridge Transformers. Biggest cab. Well, I have heard of a Celestion 27" speaker, and an EV 30" speaker both being made for bass cabinets, I think it was in the 70s.
If that is what you mean by big, then I think you have a winner. - Winner of 2006 GB&C "Best guitar build from scratch", "(Best) Most expensive build" and "Best Idea" awards - FINISHED! Member #2 of the UG Luthier's club. PM AlGeeEater to join.
