Marshall amplifiers have been around for many years. Serial numbers can help identify the age of a particular amp, but it's not always obvious how to read them. Fortunately, there are common formats used by Marshall which make it easier to determine when an amp was made.

Typical serial number formats include:

  • Four digits followed by two letters: The first four digits represent year and month while the last two indicate the day. For example, 0412AL indicates April 12th of some year.
  • Five digits with no letter: These five digit codes also represent date in either YYMML or MMDDY format depending on if the last digit is higher than 6 or not respectively.
  • Six digits beginning with an "S": This code represents dates from 1987 to 1991 where SXXXXXX stands for X representing 1 through 7 indicating months (1=January etc.), then up to 4 other characters that may be numeric or alphabetic signifying production day within said month.
  • Eight Digits starting with 94 or 95: These 8 character codes designate years 1994 and 1995 respectively as well being broken down into 2 parts -94XXXXXX & 95YYZZQQ-. In this case each part has meaning; 94/95 stands for year again, XXXX/YY stand for week within that year, ZZ are days and QQ signify production line shift during said days.

Then inspect all knobs, switches and jacks to see if there are any dates stamped on them - this could provide clues about when it was made. Additionally, certain model specific logos such as ‘Plexi’ or ‘JCM800' may indicate what era your amp belongs to. Finally, examine the capacitors: electrolytic capacitors have a date code printed on them which shows month & year of manufacture. With these pieces of evidence combined you should be able to tell approximately how old your Marshall amp is!

There are other signs to look for that could give an approximate idea of when it was made. The components used in amp production and their design can indicate its age range.

Check the speaker type, tube types, transformer windings, logo style, and circuit board layouts for clues about the age of your Marshall amp. Also consider how well it's been cared for - older amps with poor maintenance will sound different than those that were taken care of better over time. With all these factors considered, you should be able to get an approximate idea of how old your Marshall amp is.
