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.

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.

Starting in August 1997, Marshall moved to their current serial number scheme, which is easier to understand and gives more information than previous schemes.

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. This would indicate a 100W Super Lead (SL/A) built in 1989 (X), production number 10059.Before we begin, a few caveats: 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.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 - 19 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.
