There are a handful of amp types for which I'm still running the searches because I have so little data (mainly in the solid-state range).In addition Greg Gagliano sent me the Rivera-era-relevant numbers from his huge research info, for which, along with his friendly encouragement over several years, I thank him.This in turn means that these 2 amp types can only be treated together for dates or production quantities when, as in this study, the serial number is all we have to go on.(Fender did this chassis-sharing thing in earlier years, with the same implications for guessing quantities, as noted by Greg Gagaliano.) I estimate about 5500 were made in total.One run of Princeton Reverb II serial numbers seems to stretch from 1984 to 1986 with just a few from 1987, yes 1987, when some 220V models were still being sold in Sweden.So if you'd like a bit more detail on an amp in that category please get me the speaker date codes, not just the serial number. Upon arriving at Fullerton, any one of these chassis might turn out to be a Champ II or a Bassman 20, in a process which appears semi-random when tracked only by serial number.Advertisers and politicians make decisions based on smaller percentages!I'm guessing amp-owners like to know when their amp was made, if it's old-ish.
) If your amp's serial number falls into the last 3 batches then your best hope of dating it is if you've still got the original speaker.
Fender never replied, and the magazine showed polite disinterest.
So, with my dreams of being A Published Author in shreds, I might as well make what I've got available to folks.
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.
