Okay, I know you’re all just dying to skip ahead to the serial number tables but try to contain your excitement and read through the article first.
A 1957 tweed Vibrolux was reported with a tube chart printed with circuit “5E3” (tweed Deluxe) instead of the correct 5F11 (see photo).
SERIAL NUMBERS and APPROXIMATE PRODUCTION DATES 1950's to 1964 In early 1965, Fender was sold to the CBS.
The old Fender serial number scheme did not change immediately as CBS to use up existing parts and use existing tooling however a large F logo was added to the neck plate shortly after the accquisition.
Non-Schumacher transformers – It’s been universally accepted that Fender only used Schumacher transformers on amps made in the 1960s and 1970s.
Besides, no article in the Dating Fender Amps by Serial Number series would be complete without some interesting information, n’est ce pas?
I promise the tables will still be there after you finish reading.
Clearly Fender wasn’t afraid to use incorrect parts when they were in a bind. The 5G12 Concert is the earliest version from very late 1959 and early 1960 so the existence of a tweed example, while extremely rare, is certainly plausible since Fender was making lots of tweed amps during the same time period.It’s unknown if the tweed covering was a mistake (“Oops, I thought this was a 4x10 Bassman cabinet that I was covering”) or intentional, perhaps as a special order.Perhaps the best way to date the Vintage series is to carefully remove the necek and check the bottom of the neck for a production date. Oddlings – Yet another printing error has surfaced, this time from the FEI (pre-CBS) days.
Our serial number guide shows approximate date of manufacture.
For all dates, you will need to look at the construction technique and components used to get a more precise idea of the date of manufacture.
