When was my amp made?
It wasn't until the mid-nineties, when we started putting serial numbers into an electronic database, that we had more than the collective memory of the MESA crew or an amp itself to turn to in determining when an amplifier may have been built. While our focus has been on innovation and building great amplifiers, record-keeping wasn't really high on the list of priorities until more recently.
The following list won't provide an exact date for your amplifier but will indicate when specific amp models were in production. We build in chronological order (smaller numbers first). If looking for a specific date, you may find an inspection date written on your amplifier's chassis by one of our technicians (as in the photos below of both an older and newer chassis).
