Hi Richard,here's a link on your Stienway,it will tell you when it was made. Find the Age of Your Steinway Piano by Serial Number

The serial number of an Epi won't tell us the precise model.

In addition that serial number does not match any Epi data. It might be "J1.........." but even then there are too many digits.

Please check carefully.

No, but you can try:

"Serial numbers can be extremely tricky," says Gibson Customer Service Manager Jason Davidson, whose team fields calls and emails regarding every Gibson division. "Some can tell you a lot about a guitar, and some don't really tell you anything. Gibson has had so many different schemes over the years, and now we're using reissue serial numbers that look like the old serial numbers."

Serial number tells us nothing. Every manufacturer uses their own numbering and typically do not publish info about serial numbers. Brand and model might help, or just ask local guitar dealer.

From the SN alone, it appears to be a 2003. Gibson quite frequently used the first and fifth number of the serial to tell you what year the instrument was built in. But this completely depends on the model/ where the serial number is located/ if it is stamped, embedded, or located inside of a hollow body. If you can post a picture of the guitar and the serial number that would greatly help.

Can you tell me year of manufacturing Gallien Krueger 800 rb head, with serial number 43082. Thanx!
