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.
- by parts: several parts in a guitar amp have dates.
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.
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.
Starting in July 1969, Marshall starting using official serial codes.
