[quote name='Merton' post='841062' date='May 18 2010, 04:22 PM']No-one said it was introduced in 1999. The GP12X preamp and associated heads (the SMX replacement) came out in 1999.
The SMX, as far as I know, was introduced around 1992?[/quote]
You're probably right about this X series, which i didn't even hear about before
Anyway the original statement
"[i]Mar 1999 Introduction of 12-band series (GP12X preamp)[/i]"
is surely wrong, because the 12-band series was introduced in the very early nineties, with the SMX series
