I would have to collect data for ALL the amp types, just to work out how many were made of mine.
Then I became aware of the amazing work Greg Gagliano had been doing since the 1990s - the summary of his latest results are here - and that his research stopped just before the Rivera-era. However for this range of amps at least, I reckon it's not just a policy of withholding company-confidential information. It's no criticism of Fender to suggest that they were too busy making great amps to keep records just so some amateur can use them thirty years later.
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.
It would be more accurate to say that approx 650 of each of these models were produced in ’60.
I promise the tables will still be there after you finish reading.Subtract one from the other and I'll have a rough-cut figure for how many were made. PRII owners were kind enough to start sending their serial numbers in.I was puzzled to see how some of them were separated by over 100,000.The following chart, was originally printed in VG magazine, by Gerald Weber.If you see any data that is not listed here or notice any errors, for 1970’s and earlier Fender amps, please send us an email and we will update the chart.
