Hi guys! how are you? i hope you're well. Today i bought a brand new American Standard from a seller who bought it in Guitar Center, im from Argentina. The guitar sounds and plays beautifully, it's a gem and i really like the new features of the 2008 upgrade, but i have a little doubt about the serial number: it'll start with the "10" (the entire serial number is 10031373) prefix and no letter at all (i have seen some 2010 with the "US" prefix). The guitar has the 22 frets, 2 point tremolo, delta tone, etc. it's Olympic White with rosewood fretboard and has the original case with the check paper, etc. but i would like to know what's the deal with this prefix to know if my guitar is authentic. Thank you in advance and best regards!
