Dating fender bass serial number
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).
For example 55395 = 1955 920874 = 1959 1977 Forward - finally a standard serial number was used.For instance, he confirmed our assumption that the amp chassis were put into stock after being stamped with serial numbers and that the chassis were pulled from the stock bins randomly (just as with Fender guitar neck plates).He recalled, “We just went to a big bin every morning and loaded our wheeled rack with a batch of whatever chassis we were working on that day.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.Well, this universal “truth” was debunked when we found a bunch of amps with transformers made by the Better Coil and Transformers company.
These are marked with EIA code “831” and are most prevalent during the 1966-68 time period.
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.
Note the removal of the voltage selector switch and hard-wiring. I just discovered that the silverface Bandmaster speaker cabinet (the big, tall one without tilt-back legs) is ported (see photo). I guess this is what the 1969 catalog refers to as “large, individual specially designed baffles.” And all along I thought the big n’ tall silverface cabs were just a macho thing to compete against the awesome looks of a Marshall half stack or full stack.
Also note the vertical black lines on the control panel (found on earliest silverface amps) and the large ceramic power resistors coming off the power tube sockets which indicates the AB568 circuit. But really, these cabs were large because they were of a “special design” that “greatly improves tone and volume without distortion, and permits optimum performance of the speakers.” At least that’s the reason according to the ’69 catalog.
After that the foreman would add the tubes, turn 'em on and set the bias.” Export models – We’ve confirmed that Fender amps were distributed by Hagstrm in Sweden.
