Look under the chassis. It must have the date written with a marker.
Mine is from 1990.

I recently tried to find some history on the .50 Caliber and found very little on the Internet. Mesa was unable to provide much except for the following:

"Those amps were in production from:
December -1988- Thru October -1993- serial numbers FP 11,500 - FP 29,080"

Hope that helps.
