First I would like to thank everyone who responded to our request for data as outlined in the initial article that was printed in March 1997 issue of TCG.Most notably, I'd like to thank Jeff Lacio for his contributions to our research.Our evidence is that we are finding some serial numbers duplicated between models.For example, serial number A00121 has been found on a Champ dated November 1964 and a Vibrolux Reverb dated February 1965.
Fender must have had a million of these labels printed up since they appear on Champs and Vibro Champs well into 1966.If anyone has an amp with a "PA" stamp, please let us know.Still, I wouldn't be too quick to just glance at that tube chart and accept an "OA" as a January 1965 amp.The biggest tip off would be the control panels which brings us to interesting factoid #2.After CBS bought Fender in January 1965, there were still plenty of control panels for various models that were in stock.Dating Fender Tube Amps By Serial Number, Part 2 by Greg Gagliano Copyright 1997, 20th Century Guitar Magazine.It's been about 6 months since Part 1 of this series was printed so I thought it would be a good time to give an update on the Fender amp research that I am doing along with Devin Riebe and Greg Huntington.This makes things a little more interesting and difficult in playing the "dating game." And yet there is another variable to contend with as it appears that models that share chassis may also share the same serialization scheme.For instance, the Bandmaster Reverb and Super Reverb share the same chassis, and the Twin Reverb, Quad Reverb, Dual Showman Reverb, Vibrosonic Reverb, and Super Six all share the same chassis.We just don't have enough data to make any definitive conclusions yet. The author and his partners would like to thank those people who have sent us Fender amp information, especially James Werner, Tim Pershing, Gregg Hopkins at Vintage Amp Restoration, Jim Strahm and Matt Kesler at Midwestern Musical Co., and Tim Nelson at Mass Street Music.We will be writing articles in the future with more fun factoids (yes, there's more! Also thanks to the many dealers at the various guitar shows that we visit for allowing us to make notes about the amps at their booths.
