Most notably, I'd like to thank Jeff Lacio for his contributions to our research.Jeff is an amp tech who specializes in Fender amps, i.e.only Fender amps, and single handedly has submitted well over 250 very complete sets of data.Despite the heroic efforts by Jeff and other readers, we still need more data, so please keep it coming.Other things to look for include chasses placed in cabinets from a different year, “doctored” tube charts, non-original control plates (usually reproductions) on silverface amps, original transformer bell ends (they have correct date codes, of course) on non-original transformers, and non-original knobs (either repro or silverface knobs on blackface amps).unusual things can be found such as the empty “Pulse Adjust” hole on the rear of early ’60 brown amps, the “middle” volume control, use of tweed style grill cloth, strange non-documented transitional circuits, and changes in tolex color including the super-rare cream colored “brown” tolex that is found on some late ’60 amps. Given that people may refer to this information seeking specific production quantities of amps they are curious about, it should be pointed out that the serial numbers apply to chassis types, and not specifically to amplifier models.Looking at serial numbers next to the ’60 5G5 brown Pro Amp for example, we see numbers ranging from 00001 to 02000, suggesting that there are 2000 of these amplifiers made in ’60.Dating Fender Tube Amps by Serial Number, Part I by Greg Gagliano Copyright 1997, 20th Century Guitar Magazine. Well, we'll get to good parts, but first a little background information is in order.After reading Teagle and Sprung's excellent Fender amp book, I took them up on their challenge that maybe someday someone will compile enough serial numbers so that Fender amps can be dated that way. I contacted several Fenders collectors and dealers who were kind enough to supply me with data.
) and by the Fall of 1967 the conversion from blackface to silverface cosmetics was completed.Devin runs Doc’s Music in Springfield, Missouri and his interest lies in the woodie and tweed Fender amps made from 1946 through 1960.Greg and Devin’s experience meshed well with mine since I’m essentially the blackface/silverface amp guy (amps made between 19) in the group.His particular area of expertise is in Fender amps made from about 1960 through 1967.Devin runs Doc's Music in Springfield, Missouri and his interest lies in the woodie and tweed Fender amps made from 1946 through 1960.
