I don't have the link handy but I know of at least one page that specializes in Fender numbers, although as might expect it focuses on vintage guitars.Originally Posted by Spudman
For anyone looking to date a Peavey, there is a forum at peavey.com and Peavey has one employee there that will get you a date for any Peavey serial number, sfaik. Defintiely for USA Peaveys at least. Usually answers by the next day.
For anyone with any of the USA Peavey T-series (T-60, T-40 bass, T-15, T-30, etc.), iirc there is a dater page at http://www.peaveyT-60.com
