i received mine this morning and i'm amazed by the sound. it appears to be about a 75 model from the information earlier in the thread.

the serial # is 3933, it has the paper label, the bridge is NOT adjustable... the M is pearl and the Sigma is gold.

i can't tell if its lam or solid. i pulled the end pin, and its really a pin, not a screw in, but a push in, but i still couldn't really tell.

doesn't matter though, other than for a bit of ego. i have another acoustic that cost 3 to 4 times what i paid for the sigma, and the old sigma puts it down...

does this serial # tell anything? there is another number burnt into a brace near the sound hole, 227. any idea?

thanks.
