okay. i have a Sunn 412 guitar cabinet that i got as part of a christmas present probably about 5 years ago. i don't have a manual or anything on it, and i was wondering if there was any way i could find out when it was made and whatnot. its got a silver grillcloth and looks like the same one introduced in '98 with the model T, but obviously it was made before this. did they have a 412 before that? thanks for any info.
